I haven't seen one, but what I have heard is that the Apple 40MB tape drive is slow, slow, slow. For "super reliability" it writes everything three times on the tape, cutting the speed by a factor of three. There is a slim chance that when the SCSI tape support is released, it might work with third party tape drives that provide higher speed and better price/performance than Apple's. But only if you, the customers, demand it. Our Mac-II is ethernetted to a Sun with both cartridge and 6520 BPI magtape anyway. The more serious problem is that they left *dump* and *restore* off the Unix distribution! We have to do backups with tar, which doesn't support incremental backups. -- {pyramid,ptsfa,amdahl,sun,ihnp4}!hoptoad!gnu gnu@toad.com "Watch me change my world..." -- Liquid Theatre

Actually, we did have dump, restore, rdump and rrestore in there, but found a really nasty set of bugs just before freezing the production master. So, we yanked them. Almost, but not quite ... Sorry about that! :-) For incrementals, we like find & cpio. ------------------------------------------------------------------------------- Philip K.
