How to Backup Datavg(volume Group) on Tape in AIX

oraclescsa asked
Last Modified: 2013-11-17
Dear All ,
I am very novice in the field of AIX so i require the command to backup the datavg on Tape.
I am currently using this command( Savevg -f /dev/rmt0 -V datavg)  but at somepoint it is hanging or the tape is full and it is not asking for another tape. My backup requires more than 2 tapes. I am using 32gb tape. The problem is it is not asking for another tape when the first tape is completed.Anyone help in this regard

Hi again,
savevg should ask you for a new one if a tape volume gets full!
Do you see an error message or the like?
Anyway, did you ever consider using "backup" to save your data filesystem-wise, or better a third-party tool like TSM?
"backup" can process mutiple tape volumes (just like "savevg" should), and you can even premount the tapes (if you have more than one drive) by specifying a device range instead of a single device.
See "man backup" to learn about this tool.


I have not used the backup. I am going by volume groups. First i took backup of rootvg using mksysb and then savevg for datavg. I want to backup all the data in the system . Can i use Backup command for this purpose.
