This isn't rocket science. You can probably do it yourself, with a little help. Will require you to know the root password, some idea of how much space the data takes up, the ability to use tools to get the covers off and the bad tape drive out, and to replace the tape drive with something else and cover it back up.

Changing the backup device is a small change using edgemenu and edge reports the backup every time it does one to the root mailbox, if it is implemented correctly.
