there's an easy (and safe) way of doing this. if you're running unixy servers, here is what i would do (and do in fact do): install a package called amanda (free network backup software) on a server on the PRO network. it needs the tape drive, and a LARGE scratch filesystem (20GB or more, to be safe [at least as much scratch space as your largest filesystems times some multiplier]). install the amanda network backup client on each server on the PSN. the way this works is: a dump program (amdump) is run periodically on the PRO tape server, and it makes a network connection to the various clients on the PSN network. depending on how each filesystem is set up, it would command the PSN host to run tar/dump/cpio/whatever to generate a dumpfile, which is shipped across the network to the PRO server. multiple dumps can be run in parallel to different PSN hosts, and the files are deposited in the scratch filesystem on the PRO box (optionally compressed). independently, a taper process grabs the dumpfiles off of the scratch filesystem and throws them to the tape. check out www.amanda.org. the isp i work with uses this to backup a good half-dozen PSN servers every day... --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] To subscribe to the digest version first unsubscribe, then e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
