Welcome to NetVault™ for GuardianOS™ NetVault for GuardianOS is a scalable backup solution for departments, data centers and enterprises on GuardianOS, Windows, Linux, and UNIX operating systems. NetVault is built as a modular software architecture created for expansion, growth and continued enhancement of an ever-changing variety of applications. Providing enterprise-wide control in distributed and centralized environments, NetVault can operate in multi-vendor networks and support a broad range of servers, clients, database applications, storage media and high performance devices.

Update Link NetVault offers scalable functionality that can be easily upgraded to support additional servers, clients, and tape devices. Optional Application Plugin Modules (APMs) are also available for extending NetVault support to applications and databases such as Oracle and NDMP. For more information on the update options available or to purchase a license to continue using NetVault on other machines after the trial period, visit http://www.snapserver.com/bakbone.

For More Information For detailed procedures on all aspects of using and configuring NetVault, see the NetVault Administrator’s Guide available in PDF format on either the NetVault CD or the BakBone Web site at http://www.snapserver.com/bakbone. Note To access the online help from a non-Windows client machine, you must correctly set the UNIX default Web browser and UNIX browser options in the GUI > Browser tab located in the NetVault Configurator. For instructions on using the NetVault Configurator (installed with the NetVault GUI), see the NetVault Configurator Guide available on the NetVault CD ot the BakBone Web site.

Getting Started Once NetVault for GuardianOS has been installed, and backup devices successfully added through the Device Management screen, it is possible to perform a backup of data. For more information on adding tape libraries, please see Manually Adding A Library on page 7. The Getting Started section offers basic instructions on how to: 1 Perform a Full Backup of a Snap Server 2 Perform a Full Backup of NetVault Clients 3 Preform an Incremental Backup 4 Restore Data The Troubleshooting section offers solutions to common NetVault issues. There are several ways to navigate through the NetVault interface. The function of the buttons displayed on the main screen is mirrored in the drop down menus. The following instructions will assume a relative familiarity with the NetVault interface.

Performing a Full Backup of a Snap Server It is recommended that a full backup be performed on all top level shares of the Snap Server. 1 2 3 4

6 7 4

Launch NetVault and log in to the Snap Server you want to back up. Navigate to Operations > Backup. The Backup window opens. In the Selection tab, double-click the Snap Server you want to back up. The plugins available for use are displayed. Double-click File System. This displays items available for inclusion in a backup. Due to the differences between UNIX-based and Windows-based OS’s, root-level selectable items for the File System plugin will vary. Check the boxes next to drives or settings you want to include in the backup. The Schedule, Target, and Advanced Options tabs offer options for the customization of jobs. For a basic or first time backup, they are left at their default settings. For complete details on all of their functions, please see the NetVault Administrator’s Guide. Enter a name for the job in the Job Title field. Click Submit to start the job and add it to the job queue. NetVault Configuration and Troubleshooting Guide

Launch NetVault and navigate to Operations > Backup. A list of NetVault Clients is displayed in the Selections tab, including the NetVault Snap Server Client. Double-click the Snap Server Client. The plugins available for use on the selected Client are displayed. Double-click File System. A single directory representing the system’s entire file system is displayed. This item can be selected to include the entire file system, or you can navigate through the file tree directory to open individual items. Select items to create a Backup Selection Set. The Backup Selection Set can be saved for future use. To save the Selection Set: a Click Save As at the bottom of the Selections tab. b Enter the name of the new Selection Set in the top of the dialogue window. A list of previously saved Selection Sets are also available. Click OK. The dialogue window closes, returning to the Selections tab. The directory tree will now only display those items that were selected and saved. The name of the Selection Set is displayed in the field at the bottom of the Selections tab. Enter a name for the job in the Job Title field. Since this is intended to be a Full backup of the selected data, the Backup Options should be left at their default settings. The Schedule, Target, and Advanced Options tabs offer options for the customization of jobs. For a basic or first time backup, they are also left at their default settings. Click Submit to start the job and add it to the job queue.

Performing an Incremental Backup An incremental backup allows an administrator to define a backup in which only new or changed data is included in the job. This is done by first performing a Full Backup of a selected set of data, creating a starting point for the data. An Incremental Backup is then performed at a later time when only data that has been added or changed is included. Incremental Backups can aslo be scheduled to accomplish either of the following: •



Continue Capturing Data that is New/Changed Since the Original Full Backup Incremental Backups can be scheduled to continue capturing all new or changed data since the original Full Backup was performed. This type of Incremental Backup requires more time to complete but offers the shortest method to restore, as it is necessary to restore only the original Full Backup and the desired Incremental Backup to bring it up to date. Only Capture Data that is New/Changed Since the Most Recent Backup It is possible to only capture data that is new or changed since the last backup (regardless of type - Full or Incremental). This progressive form of Incremental Backup allows for the fastest overall backup, but during a restore operation, data must be recovered in the order these backups were performed (e.g., Full Backup first, followed by the first Incremental, then on to the second, and so on).

Note It is important to perform a Full Backup before creating and running an Incremental Backup. An Incremental Backup is based on the selection criteria of a Full Backup. If a Full Backup has not been performed, it is impossible for any type of Incremental Backup to be run.

To create an Incremental Backup job: 1

Navigate to the Operations > Backup screen. When the Backup window opens, click the Load button at the bottom of the Selection tab to access the Load Selection Set dialogue box.

2 3 4

Select the Backup Selection Set for the desired Snap Server and click OK. The dialogue box will close and the items selected from the original Full Backup will be displayed in the Selections tab. Click the Backup Options tab and select Incremental from the Backup Type frame. Two types of incremental backup are available: • Changed Since Last Backup — This backup only includes data new or changed since the last backup of any type occurred. Each subsequent Incremental backup would then only include data new or changed since the previous Incremental was performed. • Changed Since Last FULL Backup — This will include all data new or changed since the original Full Backup was run, ignoring any previously performed Incrementals. Select Changed Since Last Backup. All other settings are left at their defaults. Click the Schedule tab. Select Repeating. In the Schedule Options field, enter the time, date, and method desired for the incremental backup. Note Values placed in the Run At field pertain to a 24-hour clock. Make sure that the desired time is represented correctly (e.g., 23:00 = 11:00 pm). Enter a name for the job in the Job Title field. Click Submit to start the job.

Since this job has been scheduled at a specific time, it will be added to the NetVault job queue to run at the scheduled time. When the job actually runs, NetVault will assign a specific Job ID to the job as well as an individual instance number each time the job is re-run (allowing for tracking of a specific job in the other parts of NetVault). It is also possible to consolidate incremental backups into one full backup, allowing the backup data to be restored in one step rather than restoring each incremental backup.

Restoring Data This section details how to recover data once it has been backed-up. Two types of Restore are possible: • •

Performing a Basic Restore — How to Restore a full backup. Performing a Restore of an Incremental Backup — This outlines the recovery of Incremental Backup data.

Performing a Basic Restore The section covers the simplest form of restoring data: the recovery of a single Full Backup. To restore a single Full Backup: 1

Navigate to Operations > Restore.

2

In the Selections tab, Clients that have produced successful backups will be displayed. Double-click the desired Client.

3

Double-click File System to display the Backup Save Sets.

4 5

Double-click NV Server Full Backup (Fixed Drives). The root level item(s) can be selected in order to recover the complete backup. Double-click a file to display its individual contents. With the file open, locate the desired item(s) for backup and select them. You can also double-click through the treestructure to find more files for backup. Enter a name for the job in the Job Title field. Click Submit to start the restore job.

RESTORE DATA TO ITS MOST RECENT STATE This section offers two examples of how to restore Incremental Backup data to its most recently backed-up state, each based on the type of Incremental Backup performed. •



Changed Since Last Backup — This refers to an Incremental Backup of data that has been scheduled to include only new or changed data since the last Backup (regardless of type). This process requires a “stair step”procedure to restore, in which each level of the backup is subsequently restored one on top of the other. 1 Restore the Initial Full Backup. 2 Restore the First Incremental Backup. 3 Restore each subsequent Incremental Backup. This must be done in the order that the backups were made, until reaching the most recent backup, which is restored last. Changed Since Last FULL Backup — This refers to an Incremental Backup of selected data that has been scheduled to include all new or changed data since the original Full Backup was performed. This process requires only a “first and last” procedure to bring the data to its most recent state: 1 Restore the Initial Full Backup. 2 Restore the Most Recently Performed Incremental Backup.

RESTORE DATA TO A SPECIFIC POINT IN TIME This section offers two examples of how to restore Incremental Backup data to a determined point in time, each based on the type of Incremental Backup performed. •



Changed Since Last Backup — This refers to an Incremental Backup series of selected data that has been scheduled to include only new or changed data since the last backup occurred (regardless of type). This process requires the user to decide on a point in time to restore to, followed by the “stair step” procedure to restore, in which each level of the backup is restored one on top of the other. 1 Prior to initiating a restore sequence, the Incremental Backup Saveset representing the point in time must be located in the Selections tab of the Restore window. Determine the point in time to be restored to and locate the appropriate Backup Saveset. This can then serve as the target ending point for the restore. 2 Restore the Initial Full Backup. 3 Restore the First Incremental Backup in the series. 4 Restore each subsequent Incremental Backup in the series until the target Backup Saveset is reached. This must be done in the order that the backups were performed. 5 Restore the Target Backup Saveset. This will bring the data to the desired point in time. Changed Since Last FULL Backup — This refers to an Incremental Backup series of selected data that has been scheduled to include all new or changed data since the original Full Backup was performed. This process requires the user to decide on a point in time to restore to, followed by a “first and last” procedure to bring the data to its most recently backed up state. 1 Prior to initiating a restore sequence, the Incremental Backup Saveset representing the point in time to be restored to must be located in the Selections tab of the Restore window. Determine the point in time to be restored to and locate the appropriate Backup Saveset. This can then serve as a finishing point for the restore. 2 Restore the Initial Full Backup. 3 Restore the Target Incremental Backup.

The Tape Library Libraries contain at least one drive and have multiple slots that act as temporary storage for pieces of media. A library also has an electronic arm that automatically transfers pieces of media from slots to drives for reading/writing during backup and recovery operations.

Manually Adding A Library If a Library is not added using the Automatic Device Configuration, it can be added manually using the Add Library dialogue box. A library can be added to the NetVault Server itself as a Client, or to a NetVault SmartClient (a NetVault Client with direct access to a device). Adding a Library to a NetVault array that has no devices available: 1

Navigate to Device Management > Add > Add Library.

2

In the Library Selection Tab, double-click a Client name. This displays the available Libraries on the Client as well as the SCSI ID and device string for the Library.

Right-click the desired library and click Select to choose the Library. The library picture, Type, and Details are displayed in the Selected Library frame to the right. In the Drive Selection tab, double-click the same NetVault Client chosen in Step 2. A list of available drives will be displayed. Right-click the desired drive and click Select. If the library has more than one drive, select the appropriate number for each drive in the Select for drive bay box. The drive is now added. Click the Save Details button to save the Library configuration.

The NetVault Device Management window will display the new device and initialization will begin. , Only the library and drive(s) are displayed initially. As each slot is initialized, it is shown with a media title of UNKNOWN. Other media types include: • Blank — New or previously blanked media. • NetVault 5/6 NT (or other OS) — Media used under NetVault 5/6. • Other — Media formatted in some other manner. • Foreign — Previously used NetVault media will be displayed with the Media Label originally assigned to it. The prefix “FOREIGN:” will precede this media if it is not recognized by the NetVault database. This media must be scanned.

Adding a Library as Shared Libraries can be added and shared between multiple Clients. The following example illustrates how a library with two drives will be shared between two Clients that are connected by a shared-SCSI connection. Note By default, the machine performing this procedure (the target machine) acts as a Client of itself and will automatically be displayed as such. To share Libraries bertween other Clients, those Clients must have been successfully added to the target machine. This can be done through the Client Management screen. STEP 1: ADDING THE LIBRARY AND DRIVES TO THE INITIAL CLIENT The library in the example below is first added to one Client (ClientOne). This Client maintains control over the library’s electronic arm but will share the drives with an additional Client (ClientTwo). 1 Navigate to Device Management > Add > Add Library. 2 In the Library Selection tab, double-click a Client name. This displays the available Libraries on the Client as well as the SCSI ID and device string for the Library. 3 Right-click the desired library and choose Select to choose the Library. The library picture, Type, and Details are displayed in the Selected Library frame to the right. 4 In the Drive Selection tab, double-click the same NetVault Client chosen in Step 2. A list of available drives will be displayed. 5 Right-click the desired drive and choose Add Shared. 6 For the first drive, set the value in the Select for Drive Bay to one (1). Right-click on the same drive in the Choose Drives frame once more and choose Select. The first drive has now been added. 7 Right-click the second drive and choose Add Shared. 8 For the second drive, set the value in Select for Drive Bay to two (2). Right-click on the same drive in the Choose Drives frame and choose Select. The second drive has now been added. Note Drive order is critcal when adding multiple drives to a library. Ensure that the correct drive bays are used for each added drive. 9 Continue adding drives, setting the value of the Drive Bay to the appropriate number for the drive. When all drives have been added, click the Save Details button to save the Library configuration. STEP 2: MANUALLY ADDING THE LIBRARY’S DRIVES TO THE SECOND CLIENT AS SHARED Now the same library’s drives will be added to the second Client (ClientTwo) to allow for shared access. 1 Proceed from step 9 in “Adding the Library and Drives to the Initial Client” above. With the library still selected in the Library Selection tab, right-click the additional Client displayed in this window (ClientTwo) and select Open. The library drives previously added as shared will be shown with the path to them. 2 For the first drive, set the value in the Select for Drive Bay Field to one (1). 3 Right-click the same drive used as drive one (1) in the previous procedure and select Add Shared. 4 Repeat Step 2 for the second drive but set the value in the Select for Drive Bay field to two (2). 8

Note Drive order is critical when adding multiple drives to a library. The drives added in this procedure must be added in the same order as they were added in section “Step 1: Adding the Library and Drives to the Initial Client”. 5 Return to the Library Selection tab. In the Library Name field enter a name for the new library. It is necessary to assign a different name in order for the library to be added successfully. 6 With the drives added (either manually or automatically), click the Save Details button to save the library configuration.

Setting Configuration Options for an Added Library Caution It is strongly recommended that the Configuration options be left at their default (un-selected) state unless instructed otherwise by a BakBone Technical Support Representative. Once a Library has been successfully added to a NetVault Server, it is possible to set various configuration options. 1 2 3 4

Navigate to Device Management > Devices Tab. Right-click the desired Library and select Modify.The Modify Library Window opens. Select the Configure Tab. Right-click the desired Library and select Configure. The Configure Device window opens, containing two tabs: Configuration and Cleaning. The Configuration Tab contains the following: • Need Command to Open Entry/Exit Port — Alerts NetVault that the proper command must be issued prior to opening an entry/exit port. • Do Not Issue Unload Commands to Drives — Tells NetVault to ignore all Unload commands issued for the selected Library. • Must Unload Drive(s) to Open Door — Tells NetVault that Drives in the Library must be unloaded before it is possible to open the door to the Library. • Do Not Overlap Commands to Arm and Drive — Tells NetVault not to overlap commands between the arm and tape drive. • Return Inactive Media to Slot Delay — Enter a minute value in this field to create a delay between the time an inactive piece of media is returned to a slot in the Library. • Mark Unknown Media Blank — At times certain media will be marked as “Unknown” in the Device Management Window. Media of this type will not be used by NetVault when conducting a backup. Select this command to mark this type of media as Blank so that it can be used by NetVault. Note Media marked as Blank will be seen as usable by NetVault and therefore written to during a Backup. Any data existing on this media will be overwritten and lost.

Library Cleaning Drives/Slots NetVault allows administrators to designate cleaning drives and slots, set up an automatic cleaning cycle, and set the cycle’s length. Administrators can also manually trigger cleaning and view information about these activities in the Logs screen.

Configuring Cleaning Drives/Slots A drive or slot can be designated as a cleaning drive/slot when added, or an existing drive/slot can be modified. A cleaning drive/slot cannot be used for any other purpose. Be sure to note the order of the slots when dedicating cleaning shots. This prevents attempts to use those slots for other operations. Note When using shared drives, cleaning abilities should be set up on only one Client. 1 2

Navigate to Device Management > Devices Tab. Select the Cleaning Tab, and set the options: • Automatic Cleaning Supported — Select this if the target Library supports automatic cleaning. • Barcode Prefix(es) of Cleaning Media — Enter one or more barcode prefixes (separated by commas) that identify tapes to be used for cleaning. • Cleaning Slots — Enter the identification of the slots that will be used in cleaning. Separate multiple values with commas. Note Select only one field. To remove the cleaning ability from a slot, clear any value contained in the Cleaning Slots field. Click OK to save the changes, exit the Configure Device dialog, and return to the Modify Library dialog. Click the Save Details button to commit the changes.

Adding a Virtual Device Virtual devices allocate a portion of a Client’s hard drive space and act as a specific device type, maintaining all of the properties of that device. NetVault allows for the creation of either a Virtual Library, containing as many drives and slots as you are licensed for, as well as Virtual Standalone Drives. Virtual devices can be used for cleaning and disk staging.

Creating a Virtual Library Create a virtual library before adding it to NetVault. Virtual libraries can be created with as many drives and slots as desired. To create a Virtual Library: 1

The Add New Virtual Library window opens, containing the following fields: • Library Location — Input the path to the desired location of the library (/shares/VTL in this example). Now, NetVault will have access to this share as an admin user. When backing up share1 to a Virtual Library, be sure to exclude the directory containing the Virtual Library from the backup. • Library Name — Enter the desired name for the new library. • Barcode Prefix — This field contains the barcode prefix to be assigned. NetVault automatically generates a value to input in this field in order to maintain the uniqueness of the barcodes. • Number of Drives — Input the desired number of drives the library will contain. • Number of Slots — Input the desired number of slots the library will contain. When generating a virtual library, each slot will contain a piece of media. • Media Capacity (MB) — Input the desired size for each piece of media to be used. Note The value selected in the Media Capacity field dictates the size of each piece of virtual media in the slots of the library. Since each slot created contains a piece of media, be sure that there is enough available disk space to accommodate the slots (e.g., 10 slots are set up and the Media Capacity is set to 100 MB. Therefore, one Gigabyte (1 GB) of available space must exist on the target hard drive). Select OK to create the library. Based on the number of Slots and the Media Capacity set, this may take a few minutes. Upon successful creation of the virtual library, a confirmation dialog box will open. Click OK to close this dialog box. Configure the virtual library using the procedure described in Manually Adding a Library.

Managing NetVault Without Consuming a Node License (Server Version) When administering Netvault from a client installation, a node license is consumed. The server version can be installed and the local machine removed from the installation to avoid this license use. Install the NetVault GUI in the same manner as described in the Quick Start Guide, choosing Server rather than Client as described in the following section.

Server Installation and Configuration (Windows Example) In this procedure, you will install the NetVault Server software onto the client machine that will be used to administer the NetVault Server software that is pre-installed on the Snap Server. 1

Load the NetVault CD into your Windows 2000/2003/XP CD media drive. The installer menu should start automatically. If the initial menu screen does not appear in a few moments, choose Run from the Windows Start menu, and enter the following path (where D is your CD drive) and then click OK:

2

The NetVault installation wizard launches. Follow the on-screen instructions to complete the installation. When asked to choose between installing a client and installing a server, choose Server. Select a NetVault database folder. Caution If a non-existent directory is entered into the Select NetVault DataBase Folder field, NetVault will not automatically create it and the installation will fail. Configure a NetVault Machine Name and password. This name is used to uniquely identify the server on the network. Confirm and complete the installation.

Logs Debugging Without SSH For debugging, it is possible to change the directory location of NetVault logs and traces without SSH-ing to the Snap Server. 1 2 3 4 5

Login to the Snap Server as the administrator, and create a share called NetVault where the logs will be stored. In the created NetVault share, create two directories: logs and trace. Launch the NetVault interface and navigate to the Client Management screen. Right-click the Snap Server in which you created the NetVault share and click Configure. The Remote Configurator opens. In the General tab, do the following: a Click the checkbox next to Generate Debugging Files. b Change the Trace Directory file path to:/shares/NetVault/trace c Change the Log Directory file path to: /shares/NetVault/logs d Click OK.

6

Login to the Snap Server as the administrator and navigate to the BakBone NetVault screen by clicking the SnapExtensions icon, then clicking the BakBone NetVault link.

7 8

Temporarily disable NetVault by clearing the Enable check box, then click OK. To re-enable NetVault, click the BakBone NetVault link, select the Enable check box, then click OK.

The NetVault logs are now saved at the designated location on the Snap Server. This procedure does not copy any exisiting logs or traces to the new directories. However, if you re-run any backups that might have failed, the logs and traces are now stored on the Snap Server share and easily accessable. Note When debugging is complete, be sure to return the Log and Traces Directory file paths to their original states and uncheck the Generate Debugging Files box.

Password Configuration When installed, NetVault uses a ‘blind’ install. This circumvents the standard install prompt for a Netvault password. NetVault then falls back to using the ‘root’ admin password. If the Snap Server has been reset it will NOT be able to run NetVault until the default admin password “admin” has been changed. NetVault relies on the Snap ‘root’ password for access. The ‘root’ password is not set until the default admin password is changed. To change the Snap Server password: 1 2 3 3 4 12

Log in to the Snap Server using the default user name and password ‘admin’. Navigate to the Security > Local Users screen. Select the Admin user, then click the Properties button. Enter a new password and confirm the new password. Click OK. NetVault Configuration and Troubleshooting Guide

Adding Snap Servers as Clients to Existing NetVault/Snap Server Domains To add Snap Servers to an already existing NetVault Domain, use the Client Management screen. NetVault should automatically detect Snap Servers and display them in the Available NetVault Machines frame. If you cannot find the desired server on the local subnet, enter the IP address in the Find NetVault Machine box at the bottom of the screen. If you still cannot find the desired server on the local subnet, please contact Bakbone at http://www.bakbone.com to help resolve your issue.

Initial Setup with an Enterprise License/Datacenter License. Enterprise Licenses and Datacenter Licenses require a software key to be enabled on the Snap Server. For information about obtaining an Enterprise or Datacenter License key, please contact your Snap Server sales associate or go to http://www.snapserver.com and select the Where to Buy tab. Enter the Enterprise or Datacenter license key in the license field in the Snap Server UI and enable it. You can upgrade to an Enterprise or Datacenter license at any time.

NetVault Versions Prior to 7.4 Snap Servers running GuardianOS v4.2 and higher have NetVault 7.4 preinstalled. If you have an eariler version of the GuardianOS, you can upgrade to v7.4 at http://www.snapserver.com/bakbone. The NetVault management node must be running the highest version of the NetVault software in your NetVault domain. When the management node is a Snap Server running an earlier version of the GuardianOS, and other Clients in the domain are upgraded to NetVault 7.4, the management node and the other Clients become incompatable. The earlier version of the NetVault management node will not interoperate with 7.4 Clients. If you are running an earlier version of the GuardianOS, you can upgrade the management node on the Snap Server to version 7.4 by following the directions in the next section.

Upgrading to 7.4 Upgrading to NetVault 7.4 allows you to properly interoperate with your existing 7.4 NetVault implementation and incorporate resolutions for bug fixes. To upgrade NetVault to version 7.4, upgrade the NetVault server software on your Snap Server. You must also upgrade the Management GUI on the existing client used to manage the Snap Server NetVault software. You can also upgrade other agents throughout your enterprise.
