If you are writing to a disk, why re-cycle the volume?
I also backup to disk, but I do not recycle the volume, I have a separate file
for each backup of the client and I use timestamp in the volume name so every
volume name is unique. I have also set AutoPrune to yes. I modified the script
written by C M Reinehr which deletes the files for the purged volumes and
deleted the entry from the database.
I am also wondering why you use "Max Volume Duration" instead of "Volume
Retention"?
