Re: [cobalt-users] Need advice to Backup Raq2

["David B. Peterson" <dave@xxxxxxxxxxx>]

I'd suggest using dump.  It can handle backing up to the remote tape 
drive directly.  It requires a transport helper program (like rsh or 
ssh).

Below is a copy of the script that I use to backup my servers to a 
remote drive.

My tapehost is a Solaris box, but it *should* work with a Linux box 
as well.  It expects to connect with ssh to tapehost as backup. 
You'll need to make an ssh key and add the public portion 
(identity.pub) to /home/backup/.ssh/authorized_keys file on tapehost.

Check the config variables before you run it.  TAPEDEV and 
FILESYSTEMS may need to be altered.  Also, mkdir /var/log/backup.

It will only prompt you for the passphrase for the key once.  It 
holds the key in memory for the entire execution of the script.

#### config above ####
# backup FILESYSTEMS to the TAPEDEV on TAPEHOST with DUMP as OPERATOR using RSH

ssh-add
echo "Rewinding tape..."
REWIND="mt -f $TAPEDEV rewind"
ssh $OPERATOR@$TAPEHOST $REWIND
for FS in $FILESYSTEMS
do
  $DUMP $OPERATOR@$TAPEHOST:$TAPEDEV /dev/$FS 2>&1 | tee $LOGDIR/$FS.$DATE
done
echo "Rewinding and ejecting tape..."
OFFLINE="mt -f $TAPEDEV offline"
ssh $OPERATOR@$TAPEHOST $OFFLINE
