[Bacula-users] Using the same tape for a daily full backup, overwriting

Hi,

I'm trying to set a backup system where i'd use a single tape to store a
full backup on a single job. 

The first backup goes fine, and also the restore. The problem comes
while trying to run again the full backup job with the same tape on the
drive. Even if the tape is rewinded, bacula returns me an error saying
that there's no volume:

04-Jan 17:18 adhara-sd JobId 61: Job
testbackupjob.2010-01-04_17.18.47.06 waiting. Cannot find any appendable
volumes.
Please use the "label"  command to create a new Volume for:
    Storage:      "DellPowervault110T" (/dev/nst0)
    Pool:         pooltest
    Media type:   LT02

My pool looks like:

# pool for tests
Pool {
  Name = pooltest
  Pool Type = Backup
  AutoPrune = no
  Recycle = yes
  Use Volume Once = yes
#  Volume Retention = 365 days
  Maximum Volume Jobs = 1

}

Should i set volume retention to lower than a day? Can i set it to 0, so
i can run the same backup over the same tape one right after the other?
(just for testing)

thanks,

ant
