Scheduled backup - Not deleting previous versions
I'm finding that the file deletion is inconsistent. For example last night, only 2 of the 8 previous backups were deleted. I checked the log file and it shows that the first and the last databases had their previous file deleted.
Is it possible that this is somehow time related? Would a backup file being 23 hours and 58 minutes old be treated differently than a file 24 hours and 2 minutes old, when the delete backup files older than 1 days is selected?
