Ignite Backup

[Bing Wong]

Hi Everyone,
I have 2 questions:

Does the command below back up all files from all volume group to the recovery tape?

"Make_tape_recovery -A -x inc_cross=/"

Will the ignite tape created by the command below automatically create other volume groups beside vg00? My server has volume groups vg00, vgapp and vgemc.

/opt/ignite/bin/make_tape_recovery -P s -x inc_entire=vg00 -a /dev/rmt/0mn


Thank you very much.

Hi,

No.

# /opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -x inc_entire=vgapp -x inc_entire=vgemc -I -v -a /dev/rmt/Xmn

But this will create a large ignite tape an a slow revovery process. Maybe you could backup the other volume groups with fbackup for a faster trueput.

# /opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/Xmn

wil create the volume groups and logical volumes structure for the other VG's, you can use the frecover to restore the data.

Hope this helps,
Robert-Jan

Hi Robert-Jan,

# /opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/Xmn

Will it create the file systems after the volume groups and logical volumes are created?

Thanks.

Hi,

# /opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/Xmn

The command above, didnt create a file systems after the volume groups and logical volumes are created.

The command above just create the volume groups and logical volumes structure for the other VG's (vgapp and vgemc).

It's a good practice to have a seperate backup for your system :
1. Ignite/UX backup for boot disk (vg00)
2. Data backup for your vgapp & vgemc

Hope this information can help you.

Cheers,

hi,

what robert is trying to say is that for make_tape_recovery will only backup the filesystem stated in the "-x inc_entire" parameter, in this case, vg00. if u need to backup more volume group, add another "-x inc_entire" and state the group, however, as mentioned this will prolong the process.

"man make_tape_recovery" for more info on the other arguments.

regards.

Hi,

The use of ignite backup should be to backup only OS (vg00).

It is not the best tool for backuping up data in other VGs. The reason being that the application files are of no use sometimes when backup up online.

So proper backup for applications should be taken seperately as per the application specific procedure.

This also is true because ignite backup will recover system when OS disk has failed. After replacing disk and restoring ignite you can recover other VG's using vgimport command and the full recovery even if successful will take much more time.

HTH,
Devender
