Earlier this week we upgraded from SQB 5.4 to 6.1, and I just noticed that old files are no longer being removed when backups are performed. In the log file there's a time gap between when the backup finishes and when the 'process ended' message is written, which would seem to be a scan of the directory to find files to delete, but... nothing is ever removed.
Strangely, removal of old files is still working correctly on our standby server. That's running 6.2, but I reviewed some logs from when it was running 6.1 and file removal was working then as well.
Any suggestions for what I can check to see why it's no longer working?
