Backup And Restore In Red Hat

Backup & Restore :

In computers, a backup or the process of backing up is making copies of data which may be used to restore the original after a data loss event.

For the backup “tar” command is used.

#tar option destination path source path

if you take the backup /etc dir? then

#tar -cvf /tmp/etc.tar /etc 
#tar –zcvf /tmp/etc.gz /etc
#tar –jcvf /tmp/etc.bz /etc

#du –h /tmp/etc.*

NOTE : First you go to the dir where you decompress the backup.

#rm  -rf /etc
#exit
#cd /
#tar –xvf /tmp/etc.tar    
#tar –zxvf /tmp/etc.gz
#tar –jxvf /tmp/etc.bz
