Hello,
Bacula maintains certain simple metrics about particular Volume (tape)
usage in the Media record of the catalog. So as long as you do not
delete Volumes from the catalog, those metrics will persist. Another
method to get metrics about particular tape Volumes is to use the
tapealert code that was implemented in version 9.0.0 -- see my email
post just prior to this one.
We are continuing to improve metrics, and sometime in the first half of
next year, we will release code that allows you to continuously monitor
the SD (also clients and the Director) using Graphite.
Best regards,
Kern

Thanks, I know what Wikipedia says. My question is
about how can Bacula help to monitor these metrics.
Bacula does maintain metrics on each volume should
you want to monitor their usage.
How exactly? If a volume is purged (manually or say
every N months) - how can Bacula maintain metrics
about it?
Another thing: Which is better (and why) in a scenario
when a full backup with multiple incremental ones
cannot fill a single tape:
A)
Full backup
Incremental
Incremental
...
Purge after 3 months (tape about 1/3 full only)
(repeat the above)
OR
B)
Full
Incremental
Incremental
...
Full
Incremental
Incremental
...
(until tape gets filled, then purge and repeat)
