Nfs Automatic Backup Script - Rhel5

MANUAL FOR AUTOMATED BACKUP THROUGH NFS --------------------------------------Things to Do:Here are two script file coding is given you have to copy its content to a new file with server_copy.sh and client_copy.sh respectively.. Scripts :1. server_copy.sh 2. client_copy.sh NOTE ----- During script execution pay special attention to the output. - Jot down all the enteries which you enter during the script running as undoing is not possible after any entered text - Do not rename client_copy.sh - Do not confuse with Client or Slave keywords both reference to the Second machine - This script is made to take backup hourly... NEED ----The basic need for this type of backup is concerned for few machines. Where Server will be your main Machine which has important data and Slave(Client) machine which will required when main machine some how stop working. DISCLMAIR ---------I have run these scripts on RHEL5 machines and never got stuck, but i'm not guranteed with other Linux machines so i will not be responsible for any damage to your machine or leak of data. So you have to run these scripts on your own risk. For any suggestion, queries and bugs you are always welcomed at [email protected] HOW TO START ------------ Copy both .sh files to the main server then execute server_copy.sh # sh server_copy.sh or, # ./server_copy.sh --------------------------------SCRIPTS ------------------------------------
