Thank you for your quick response. I appreciate the reply and advice. However, I am under certain restraints in that there is no wish or desire to purchase any new software and the only stated purpose for the tape backups is for disaster recovery purposes. I was hoping to find out what would be the most efficient way to do multiple volume backups so that I could determine the most efficient way in which to label and record the contents of the tapes.
We use veritas netbackup and are very happy with it. Is it a financal restraint stopping you from spending money on a proper backup solution ? If so and you don't want to backup cifs acl's ( well use cifs at all ) then consider using amanda and backing up over nfs. Its got a reasonable chance of working although I would have a tendancy to give it a separate ethernet to work on.
if you want to use dump and the stacker then just repeat the device multiple times and I believe it will load the next tape. I also believe you will cost your company more in the long run by not buying good software to do this job. Amanda is good free software but you would have to use nfs, it may be possible to back cifs shares up using samba and amanada.
The only way I would be able to run with just a stacker would be to do a weekly dump and fill the device first then empty after the run labeling each of the tapes with the week and tape number.
