I've found that virtual-full backups are a bit nicer than copy jobs for
off-site storage. They take the most recent full, differentials, and
incrementals and combine them to be a single new full backup that has
the latest view of everything. But what you want can also work with
copy jobs.
My pool looks like:
pool {
# No "Label Format" disables automatic volume labeling
name = offsite
pool type = Backup # Sigh, case sensitive
storage = lto6-1
volume retention = 30 days
maximum volume bytes = 2500 GB
volume use duration = 48 hours
purge oldest volume = yes
}
We do off-site backups once a week, so clearly you'll need a longer
VOLUME RETENTION period. The trick for me was the VOLUME USE DURATION.
Which is:

The 48 hours is about how long after the backup starts that we move the
tapes off-site. Label the 4 tapes, put them all in the same pool, and
Bareos will cycle through the tapes for you.
