you are most welcome. i hope you can get some mileage from scripts.
cpio works very well for tape archive. i started using cpio w/ basic scripts
in mid 70's for backing up 10 and 20 meg hdd's and has yet to fail.
'testscript' is best done to insure you are getting what you want from 'find'.
with find and grep, cpio even does a fine batch/conditional file transfer.
peace out.

I've got one more question. The other evening I was mucking about working some kinks out of my backup script and I think I "over-filled" the tape. When it got full, of course, it started returning a lot of errors to the console, and now I can't get it to run at all.
When I try to run it from the command line I'm getting this returned to the console:
tar: /dev/st0: Cannot open: No such device or address
tar: Error is not recoverable: exiting now
tar: /dev/st0: Cannot open: No such device or address
tar: Error is not recoverable: exiting now
I got to diggin around in the log files and found this:

I've tried reloading the module for the device, but to no avail. It appears from the log entries that it got disabled some how when the kernel received the errors from the hardware, and I haven't a clue as to how to re-enable it. I've tried rebooting the machine, but that didn't help either. I'm sorta stumped here. Any ideas?
thanks,
Mark
