> (ns)sbackup does not purge incremental backups (in the latest version)
is not totally right: logarithmic purge works in SBackup 0.11+, however the fix is not yet ported to nssbackup 0.3 (and I'm not sure it ever will). See bug https://bugs.launchpad.net/nssbackup/+bug/587911 to track progress made on this. The rest said by Anton is basically right: snapshots get only purged (logarithmic plan or simple cut-off) in the case they are _standalone_ (i.e. other snapshots do not depend on them). Purpose is to keep incremental and full snapshots consistent. Rebasing of incremental snapshots as in nssbackup before 0.2.0 is completely dropped since it is a severe risk to the backuped data. Version SBackup 0.11 introduced a slight modification of the logarithmic purge plan: * keep all from yesterday * keep one per day from last week * keep one per week from last month * keep one per month from last year * keep one per quarter from 2nd last year * keep one per year further into past Read 'keep one' as 'keep at least one'. @dik23: making a full backup every 30 days means purging of snapshots will be possible not before 30 days after the first snapshot because every snapshot in your archive relies on the other (except the latest but this one is also kept because it's the latest ;-) until you create another full snapshot.
