Cleanup job removed files that are more recent than specified

Post by Panos » Mon Dec 31, 2012 7:53 pm

I have set up a cleanup job that removes all backup files older than 3 weeks - except for full backups. It is expected to remove all incremental and differential backups older than 3 weeks. In the few times that I have checked it during the last few months, the state of the backup directory was as expected.

However, when I checked recently, I noticed that recent incremental and differential backups were totally missing from the backup directory. Looking at the log of the corresponding cleanup job I found that it had in fact removed files more recent than 3 weeks.

Here is the log of the cleanup job. Please note that the last two backups (153, 154) are within the 3 week period. In fact, the last incremental backup was only produced a few hours earlier.

Thanks

Hi,

Please note the incremental backups are based on the previous backup execution: incremental, differential or full.
If you select to delete an incremental or differential backup version older than 3 weeks ago, all backups depending on it will be deleted too, otherwise they would be useless.

Were the recently deleted backups based on a recent full backup? or they were based on a differential/incremental backup version older than 3 weeks?

Hi,

Your explanation seems to correctly describe what happened.

However, I wouldn't call partial backups (differential/incremental) which are missing the previous ones they depend on as 'useless'. Even though they do contain only partial information (only some of the recently modified/added files) they may still be valuable, particularly in the case of errors.

Please consider a) the surprise factor - backups are deleted even though the user doesn't expect them to b) although the core backups are deleted from the system, they may already have been e.g. burned to DVD (which I do)

I would suggest that the system not be aggressive in terms of deletions and just follow the user's instructions re: timestamps.

Thanks
Panos

Hi,

Backup4all was designed to keep the backups into an organized structure and not keeping only parts of backup.
