- | I think Mark heard about the "brutab" problem with DATs and if he sends me
- | his FAX number, I will send him pages 12&13 from the Sep/Oct issue (V3#5).
-
- bru works fine (better!) if /etc/brutab is not used, or if everything
- therein is commented out. In particular, the size field should always
- be absent, or set to 0. I don't remember seeing that article, so I
- won't comment further on it.
-
- In general, I would strongly recommend that people not use bru, since
- it isn't very portable, and uses more tape. The fact that our own system
- backup and recovery mechanism uses bru does not change my recommendation.
