Filesystem backup vs make_tape_recovery

[Jorge Fabregas]

Hello everyone,

I've been using make_tape_recovery to backup my systems. These days I've been working with RMAN (for Oracle) to backup the database via Veritas NetBackup. I'm wondering (now that we have Veritas Netbackup) if we should do filesystem backup for the OS?

Is it enough having the make_tape_recovery backups? Any advantage doing filesystem backup? Will I have error regarding open files? I can't think of any advantage if I already have the make_tape_recovery (which includes all vg00). Perhaps I won't be able to restore a particular file from make_tape_recover right? Is that the only reason? What are your suggestions?

Thanks a million!
Jorge

Ignite make_tape_recovery is really intended to be a disaster recovery solution to rebuild your root disk so that you can then use a regular backup/restore package to rebuild the rest of your data. With a regular backup package you have the advantages of being able to schedule full and incremental backups, track the tapes used, recover individual files and directories with ease, and other advantages, I'm sure. I would always use Ignite as only a part of my overall recovery strategy.

Hi Jorge,

YES, maybe not as frequent as you did before but Ignite is perfect for disaster recovery. I use Legato + Rman and once a week an Ignite backup (vg00 only).

In case of a disaster I can boot a system with the ignite tape and restore the data with Networker.

Hope this helps,
