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! -- Mike Holden http://www.by-ang.com - the place to shop for all manner of hand crafted items, including Jewellery, Greetings Cards and Gifts
