On the whole, dump is safer. Would some knowledgable person care to comment on bru in light of Elizabeth's comments above. We use bru to back up our SGI 4D/240S with 6GB disk (five 1.2 GB drives) We back up one drive a night and do an incremental on the rest. The system is usually fairly quiet when the backup is done (in the small hours) with only a small number of batch jobs active. We have had no trouble, yet, and have had to restore a disk on two occasions in the last year. Cheers, Russell. -- Russell Fulton, Computer Center, University of Auckland, New Zealand.
