I guessed, but it should be overwritten even with a timestamp. That or make it clear that overwriting doesn’t work with timestamping enabled.

overwrite option these is only to make sure you dont want to update existing archive when they have same filename. It is not there to delete old backups.

what we can do is disable the overwrite checkbox when timestamp is select, so there is no confusion.

When ‘Overwrite previous file’ and ‘Add time-stamp to the filename’ are checked when using the backup utility the old backup isn’t overwitten.

add-time stamp will create unique filename and it will not overwrite previous backup… if you uncheck it, then it will be same filename as before and it will overwrite it.
