Hello,

I want to backup my PE2800 on tape but I'm not sure how to do this.

My PE2800 has a RAID5 setup with 2 72GB SCSI disks and a Seagate DAT-2 72GB
internal tape-streamer and I'm running Centos 4.3 with the latest yum
updates.

I'm not sure if this tape-streamer is recognised by the OS properly because
it doesn't show up along with my DVD/floppy

I also recieved with the server a copy of Galaxy Express software from Dell
but from what it looks this seems to be more of a client/server
backupprogram and not really functional on a standalone server.

So how does one backs up + restores a complete HD (incl. MBR) like a ghost
image or something on a tape. Any good software or howto's you can suggest
would be much appreciated.

kind regards,

Geert
    

Geert,

Have a look at the mt command. This will amongst other things show you the 
status of the tapedrive ( mt -f /dev/mt0 status ). /dev/mt0 is most likely 
the devicename for your tapedrive.

I can recommend Lone-tar from www.cactus.com. Have long time experience with 
it, very good and solid. Bare metal restore from two floppies (or CD) and 
your tape in under 2 hours. Lots of options but still easy. You can download 
a trial version.
Costs somewhere between 400 and 500 Euro's. If that's is too much, have a look 
at Bacula. No personal experience with that though.

Good luck,
