Red Hat

Hi,

I am new to RHEL. and started exploring/learning RHEL from last few months.

I understood LVM and other system admin concepts. But I did not get a chance to explore backup/restore options in RHEL.

Can you please explain the procedure on how backups/restores work in linux environment?
Please explain.

Thank you

There are a number of ways of doing backup and restore of RHEL fileystems. What you use depends on your configuration and how you wish to do backups.

For example, if you have an XFS filesystem, you could use xfsdump and xfsrestore.

For LVM, you could use vgcfgbackup and vgcfgrestore, lvmdump, lvmsnapshot and more.

For ext3/4, you could use dd, tar, cpio, pax and lots more.

Thanks for your reply. I understand that, some commands/utilities are available on RHEL OS. But, are most of the customers using these tools for backing up OS. so that they can use in case of disaster?

please let me know high-level practices/procedure for backing up OS and app/db's.

Thank you.
