How can I use the remote tape drive to take backup of a filesystem in RHEL server.

Hi,

We have a RHEL AS 3 server, whose file system need to be
backed up.  We
donot have a tape drive on it.  We have a tape drive on
another remote
server (AIX, /dev/rmt0).

How can I use the remote tape drive to take backup of a
filesystem in RHEL
server.

Please suggest,
Thanks & Regards,

There's plenty of ways of doing this. You could try using a
free backup
system such as Amanda (http://www.amanda.org/) or
Bacula
(http://www.bacula.org/);
or one of many commercial alternatives
(Legato, Veritas, Arkeia, etc)

A simple, but more difficult to manage, solution would be to
write a
bunch of shell scripts using rdump, or to be slightly more
secure, using
tar with ssh & dd.

Eg, tar cf - / | ssh remotehost dd of=/dev/rmt0

Make sure you've set up your ssh keys first...

Cheers,

Paul.

You can you tar or cpio

for cpio something like:
find /src -print | cpio -o -C 32768 -H crc -O useraix:/dev/rmt0 
--rsh-command=/usr/bin/ssh
where user at aix has to have write access to /dev/rmt0


tar --rsh-command=/usr/bin/ssh -cvf useraix:/dev/rmt0 /src
