Attached is the script I wrote to take care of this. What I found is that over
time,
backups are occasionally larger than expected due to events like software
updates or
whatever, and disk space usage slowly increases. I initially took care of this
by adding
extra space using LVM to grow the partition and reiserfs to grow the filesystem
into the
new space. Eventually though, you run out of physical disk to add!
Although in principle it is good that bacula keeps backed up data until it is
re-needed,
in practice, it can lead to infinite disk space growth over time.
The attached script is php, and connects to the bacula database (plug in
appropriate
user name, password and server name in the connect statement at the top). It
first of
all looks for volumes past their expiry date and purges them. It then looks for
purged
volumes and deletes them. Finally, it looks in the backup directory (plug in
your
location here) for files with no matching database entry and deletes them.
Use at your own risk etc. I'm not responsible if it deletes your backups,
crashes your
car or causes your freezer to thaw out!!!
Automated removal as detailed by Marek above is difficult to implement simply,
because
you will probably have multiple retention periods on your files, and you need
to take
this into account in your deletion. Plus, deleting the files while they are
still listed
in the bacula database is possibly not a good idea!
