You can either use NFS to mount the other systems drive on the backup
machine or you can use the remote tape access capability of tar to
effectively do the same.  To use tar:

cd /
tar cvf backupmachine.your.com:/dev/rst0 .

Permissions have to be granted on the tape machine to give the other
machine access.  Look at the rmt(8) command for more information.

Better yet, use Amanda.

The current release is 2.4.0 and there isn't a port for that yet.
We use it on Solaris to backup 4 servers on one tape drive.

Bzzt, thanks for playing!

"amanda24" is the port you're looking for.

I think it was done because there've been a few incompatibilities that
have been introduced recently.

It's hell to install on some older systems, but it's a great package,
and compiles nicely under FreeBSD.

1. Backup utilities other than tar and system backup?

We have about twenty tapes in our office which were supposedly backed up
with tar on aix 3.2.5 on an ibm branded EXB-8505. Attempts to restore them
on our aix 4.2 machine, with the same tape drive or the ibm 7208 341 result
in the same following error messages, when trying to list the contents of
the archives:

AIX tar:
0511-193 An error occurred while reading from the media.
There is an input or output error

gnu tar:
Read error on /dev/rmt0: I/O error
At beggining of tape, quitting now

pax:
[offset 0]: there is an input or output error.
0511-658 Unable to determine the archive format

restore: failed
0511-157 Cannot skip tape records

Any suggestions on what program might work for these tape or any
recommendations on fixing this problem with the current setup?

Thanks,
Michael Thilmont
