Hi Björn,

The incremental backups depend on it, so BackupPC ensures that they work
by keeping the full until the incrementals also expire.

For example, if you were to decrease IncrKeepCnt and IncrKeepCntMin to
0, all but the latest backups should be deleted automatically.

Not sure why one would do that except for testing purposes, though :)

Best regards,
Johan Ehnberg
