Ignite Differential Backup

[sk800i]

Hi,

Does Ignite-UX can run Differential/Incremental Backup? I'm using v11.23

If no, how can I use backup for system backup with Diff/Incr Backup?

No, Ignite is intended as more of a DR solution, thus it backups and restores a whole system. You probably should look at fbackup for your needs.

Hi Pete,

Can fbackup command backup a whole system too?

I want to use full backup on Sunday and Diff backup on week day and weekend. When the system crash, I can restore it using Full backup tape + Diff backup tape.

regards,
Simon

Hi.,

It would be a good idea if you do an ignite backup too once in month..
With Ignite backup it allows you to boot from the ignite server or tape when the system crashes and recover the system as it were when the ignite backup taken.

And once the system is recovered you can restore your other data from fbackup tapes.

[Torsten.]

Please think about the concept.

Ignite takes a full "image" of the operating system (vg00) and is able to restore it - even to an empty disk.

fbackup can take full and incremental backups, but it needs an running OS prior to restore a backup.

Depending on your hardware, an ignite backup could take ~15 to 20min (fast hardware) for a full backup of the OS (vg00).

No incremental backups with ignite are possible.

Hi Simon,
I would like to add following:
To take a full backup of vg00 in a tape use the command:
#make_tape_recovery -a /dev/rmt/XXmn -I -v -x inc_entire=vg00
If the system crashes you can recover the operating system very easily from this Ignite backup.

To take the fbackup use-
#fbackup -v -f /dev/rmt/0m -i /etc â e /etc/lp
The above backup will includes every file under the /etc directory tree except the /etc/lp subdirectory.
Hope this will help.

Regards,
Davis Paul.

Dear Davis,

Thanks your info. If I use fbackup to backup a whole HPUX OS (/, /etc, /var, /usr, /opt, etc), when I use frecover to recover all mount point. Do I need to use lvlnboot to root mount point otherwise it cannot boot up the system?

If yes, how to use the lvlnboot command? Can you give an example too?

Platform: rx2660 (v11.23)

Shalom,

Your last post is a bad plan.

Use Ignite to back up the boot volume, vg00.

Use fbackup to backup user data. Put oracle databases and such in backup mode so with some sql code before attempting to get a backup of them.

fbackup is good for regular files, not really good at database backups. A professional tool, like DP 5 or Veritas Netbackup or Legato is better.

A complete DR solution includes two things:
1) Ignite for the Core OS.
2) Another tool for the user data.

Hi,

Try reading OReilly.Backup.and.Recovery. it provides in depth Bare Metal Restore and Different backup types guide.

It also list many OPen Source and commercial backup solutions for Unix/Linux/Windows/Oracle/MySQL

I recommend reading....a definite good guide and good source of information.

This book got me interested in researching about AMANDA and Backula backups..

According to me backup itself is a big subject and requires alot of planning and practice.
