Hi List, I have a situation where I cannot keep all my backup tapes in autochanger. Instead, that ones that are not going to be used during the week must be kept in a vault storage. I would like to keep in autochanger only the tapes that Bacula will try to use the next week and have this information sent to me by email. How much tapes and pools used can vary. I tried using list nextvol and various other Bacula´s options, but without success.
So, I tried to create a shell script that could retrieve this information.
Basically, the script do not check the following:
- how many volumes will be used for a backup job;,
- if PurgeOldestVolume or RecycleOldestVolume directives are set;
- if automatic or manual prune or purge are configured or intended to be
used
- if volumes are InChanger or not, just for the case of VolStatus=Append
The script outputs a list of a number of expected volumes to be used from a
Pool that could be used for backup in a specific datetime. For example, to
list all the volumes (you can set a value using --vols) from WeeklyPool
pool to be used at "date +'%F %T":
/opt/bacula/scripts/list_available_volumes.sh --pool=WeeklyPool
--date="$(date +'%F %T')"

The WeeklyPool has a 40 days volume retention time and the volumes
000009L5, 000010L5, 000044L5 and 000056L5 will not be used by Bacula at
"2015-03-23 15:25:40" (the output for "date +'%F %T") without operator
intervention. But this list permits the operator to be prepared for a
manual prune/purge if it become necessary.
The usage and parameters for the script are documented in the code.
I´m affraid I was not able to find an easy way to have this information
with the actual code/scripts/queries from Bacula. If there is a better
solution for that, please advise me.
The script was tested with a small catalog. So I appreciate your help in
testing this.
Best regards,
Ana
