SCO Unix's backup and restore programs (and the sysadmsh interface) is really just a front-end to cpio. Write your own in shell scripts; it's not that hard. You can do everything you mention above with find, cron, and cpio, except for the NFS part. The basic problem with backing up a NFS-mounted filesystem is that your root access on the local machine means nothing; you can't read any files that "nobody" can't read. Unfortunately, SCO doesn't supply an rtaped program. Your best bet might be to spawn an rsh on the system you're NFS-mounting from, run cpio *there*, and pipe the output to the tape drive on the local machine. Of course, this raises a lot of nasty issues of security, but hopefully the machine with the tape drive is not a machine that a lot of bad-security-risk-type people have root access to. -- Marc Unangst | mju@mudos.ann-arbor.mi.us | "Bus error: passengers dumped" ...!umich!leebai!mudos!mju |
