Savevg

[redwings]

Is there a command for the savevg that will only keep the filesystem information without backing up all the files. I do a regular backup but I would just like to run a savevg to save the filesystem information and then restore that and then restore the data.

Thanks.

When restoring this, would you just do a restvg and point to vg.data file or is there something else that needs to be done?

Hi

I think that you are wanted for a map to restore unknows files if a day you lost your server... BUT, i think that you must to have a recent mksysb. (Regenerated after all filesystems modifications ! expand FS => mksysb ... always !). the last mksysb provides normally informations which you need.

This is what we do for disaster recovery

To save the information about your vg use this command:
savevg -f /tmp/xxxx -v -i -e xxxx

The xxxx is the name off your vg. This saves only the information about the vg and not the data

Then make an mksysb

In case of an recovery you need to restore the mksysb and then do the restvg command to restore the vg. Then restore the data.

Marcel,

When running the command that you stated, it tries to copy all the files into that file that is created.

Thanks,

Bill,

When i run the command this is the result:

# savevg -f /tmp/oravg1 -v -i -e oravg1

Creating information file for volume group oravg1.

Creating list of files to back up.?*+ not preceded by valid expression.


Backing up 6 filesBacking up to /tmp/oravg1.
Cluster 51200 bytes (100 blocks).
Volume 1 on /tmp/oravg1

a 98 ./tmp/vgdata/vgdata.files
a 3647 ./tmp/vgdata/oravg1/filesystems
a 0 .
a 2260 ./tmp/vgdata/oravg1/oravg1.data
a 331 ./tmp/vgdata/oravg1/backup.data
The total size is 6434 bytes.
Backup finished on Fri Aug 4 07:16:37 2006; there are 100 blocks on 1 volumes.

It writes an file /tmp/oravg1 and if you look in /tmp/vgdata/oravg1 you will see there the information what you need to recreate your vg.

In case of an total disaster you need to restore the rootvg, then recreate the vg whith this command
restvg -q -f'/tmp/oravg1'
and restore your data.
In other cases you only need the restvg command
