Hi

It depends on the software you use. Can you please give more details.

How are you backing up? Some backup products insist on using the rewind device file.

For example (from man fbackup):
fbackup should not be used with no-rewind devices, for example, /dev/rmt/0mn.

Hello,

Given that the Ultrium 230 stores 100Gb of data natively (without compresion; with compression it will be even more), you can do that of course.

Using Omniback II, this is easy, as this software puts multiple sessions on one cartidge automatically.

Using tar, you have to do this manually by moving the tape forwards using the mt command.

E.g. If you want to move the tape two tar sessions ahead, type:

mt -t /dev/rmt/0mn fsf 2

Remember the mn, this is the no-rewind device file.

HTH,
Vince

To my knowlegde the Ultrium230 are faster in backup and restore Time.
Around 200GB is backed up in 2hrs as per HP standards.

I dont think you can simultaenously run a parallel backup job with this model.

It will be queued.


Thanks

I use system software fbackup, tar
P.S. file more 2 GB

Yuri,

As previously stated, fbackup won't work for you, it insists that you not use the "no rewind" device file so subsequent backups will just overwrite the first. Tar could work but for files over 2 GB, you're probably going to want to use the gnu version. Best solution would be to get HP's Omniback.

Hi

I don't think it is a good idea using a 200GB backup device without a "real" backup program (as HP OmniBack,Legato NetWorker,Veritas NetBackup etc). I think you will get problems administrating your backups.
