How to backup and restore VxVM?

[Ryan Gu]

I want to do a backup for rp7410.
The rootvg is lvm. Other disks are used VxVM.
How can I do a backup and restore when I reinstall OS of rp7410?

Hi Jason

1. Take a full backup using fbackup.
2. Install Minimum OS using install media
3. Restore the full backup taken using frecover

Create two good Ignite tapes before you start the upgrade.

Jason,

Backup of root vg is the most important. As suggested earlier, take ignite backups ( using "make_recovery -A " ). It is also a good idea to have additional copy of /etc in a easily accesible location ( a different disk location instead of tape) to compare old and new configuration.

Backup other VxVM volumes using Fbackup - just to be on safer side. But you'll not need to restore them.

Deport the VxVM DGs before the reinstall and After the reinstall just import them back - all you date "should" be back....

Hi,

The default tool for system backups (vg00) in HP-UX is Ignite. For the other volume groups you can use your ordinary backup tool (I belive you do backups).

Thank you for your all reply.

I'm draw up a disaster recover plan. I will test it follow your advice.

Jason,
accordingly to what correctly said by other forumers, this is an useful link for you:

I'm do the test.

I found that I could not deport rootdg. ( My system is in LVM and data is stored on the Veritas volumne.)

When I do a make_recovery tape, whether the rootdg's information is backuped? And whether it could be restored when I restore system by make_recovery tape?
