Best practice to backup Lv
i try to use tar , but i think it only create one file inside the tape.
my lv are :
/dev/vgsapdev/lvusrsapput
/dev/vgsapdev/lvsapd01
/dev/vgsapdev/lvsaptrans
/dev/vgsapdev/lvinfd01
/dev/vgsapdev/lvsapmnt
they all on different mountpoint.
How can i backup them ? and the restore it, since it's not root vg so i can't use make_recovery.
Responses really appreciate, thank you all :)

Re: Best practice to backup Lv
if you would use tar for more file you can use the no rewind tape (example /dev/rmt/0mn ) in the tar command.

Re: Best practice to backup Lv
I think you should use SAM:
Type sam as root and go to Backup and Recovery -> Interactive Backup and Recovery -> [select the backup device OR go to Actions -> Use Remote Backup Device if the tape drive is in another server ->] -> Back Up Files Interactively... and select the files/directories you want to backup.

Re: Best practice to backup Lv
I would run a vgexport with -p and -m to create a mapfile.
This is quite helpful when restoring a system.
You can use make_tape_recovery/make_net_recovery to back up the boot partition and all logical volume information.
You can use fbackup.
You can create one tar file and then re-tar it to tape.

Re: Best practice to backup Lv
If you are looking for saving the VG configuration, you can use the 'vgcfgbackup' command.
Doing an Ignite on vg00 is always a good idea and this will get the /etc/lvmtab file.

Re: Best practice to backup Lv
- i am not sure, but you can take a try using make_tape_recovery to backup non rootvg
make_tape_recovery -p -v -x inc_entire=vg01
- why you need a nonroot vg image backup? we actually dont require image backup for nonroot vg. It is better to go for a normal backup with tar, fbackup or other 3rd party backup softwares.

Re: Best practice to backup Lv
tar cv -C mountpoint1 . -C mountpoint2 .
You get the idea...
To recover this data:
tar -xvf /dev/rmt/0m
This will extract the data into the respective directories.
