Using tar, to make differential Backup on Hard Disk
I am new member of Linux Family. I have been assigned the task to implement system in Red Hat Linux 9.0 as Backup server.
This Server also contains users data on Raid implemented ATA/100 Drives.
I would like to find the way how would I create the backup of data on Raid Implemented HDD on another Drive.
Case I - Differential Backup
I had find the way by using tar command but didn't get success. I used
$ tar czf /home/user1 >user1.tar
I used this but I didn't know How would I get differential backup.
Case II - Automating the back up process on Daily basis
I had used the "crontab" settings but I failed
I had add following statement in /etc/crontab as
30 17 * * * /bin/tar cvzf /user1.tar /home/user1
Please any one could help me out.
