Hi!

I use puppet for dynamic configuration management where clients basically register with the BackupPC server for backup. I now face the problem, that due to a config error/update/etc. a client might be dropping out for a few days. This leads to BackupPC's host file to be updated and BackupPC_nightly will clean the now unused files.

They only related option I found right now is changin $Conf{BackupPCNightlyPeriod}:

How many days (runs) it takes BackupPC_nightly to traverse the entire pool. Normally this is 1, which means every night it runs, it does traverse the entire pool removing unused pool files.

Other valid values are 2, 4, 8, 16. This causes BackupPC_nightly to traverse 1/2, 1/4, 1/8 or 1/16th of the pool each night, meaning it takes 2, 4, 8 or 16 days to completely traverse the pool. The advantage is that each night the running time of BackupPC_nightly is reduced roughly in proportion, since the total job is split over multiple days. The disadvantage is that unused pool files take longer to get deleted, which will slightly increase disk usage.

Is there any other option to delay the cleanup that is caused due to such misconfiguration?

Thanks,
Raoul
