Would anyone know if there are any tape management packages available for Unix. Ideally, we would like a package that was integrated with a backup and archiving system as well. Packages something like Rabbit for VMS or UCC1 for MVS would be what we are looking for.

The only reason I am not currently using it is due to a problem with the AT&T UNIX V file system, not with the product. With my version of AT&T UNIX V, the maximum logical block size is 1k in a file system. With this small logical block size, the disk drives could not "feed" data fast enough to the tape drive (the transfer rate was 30k/second and the tape drive I have can handle about 200K/second). A complete monthly backup of 2 gigabytes of data took over 48 hours and (18) 2400 foot tape reels. The Ubackup product does not cosume much CPU power though. If your version of UNIX uses the fast file system, this product may offer the features you need. If there are any more questions, please contact me.

And I thought *we* had it bad at 6 hours for 2 GB! :-) (This on an 8250 dumping from CDC9771s to TU80. Fortunately, this will probably drop to ~3 hours dumping to one 8mm tape [yes, the 8mm tape works on the 8250 BI Unibus, despite recent comp.os.vms/info-vax mail].) (Incidentally, 2GB is more on the order of 25 2400 foot reels at 1600 bpi.) -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7163) Domain: chris@mimsy.umd.edu Path: uunet!mimsy!chris
