Well, if your tape device was /dev/st0, you could:

cd /
find . -print | cpio -ocvB > /dev/st0

Go visit

http://www.storix.com

and download their FREE backup suite for a single system. If you are familiar with AIX then this utility will be familiar to you. It will create a complete system backup and, along with a set of bootable diskettes/cdroms, you can cold boot and reinstall a complete system.

We use it for production and it works just great!

You can use # dump command line to backup your system on linux. Man dump to get more detail information.
You should login as single user mode to do the system backup.
Good Luck....

why not `tar' ?

 

[stanhubble]

why not dd....
the short and long of it is that there are many methods and tools to do backups. the important thing is to use them and verify the backups. we have had good luck with the supertar's ( lonetar, backupedge..etc)

You can use tar. if you do the backup for few directories not backup all the system.
Good Luck....

What are you trying to backup your entire system to ? A tape, another disk, a remote UNIX machine ???

I did the following:

-dd for initial image to a 2nd drive... there was a FAQ for this, but it's gone... basically boot to a Linux boot disk then type 'dd if=/dev/hda1 of=/dev/hda2' or whatever the drives are!!!
-now I user rsync to copy changed files from /home etc.

I've tested, and I'm able to swap drives and boot from my 'backup' drive.

Since I'm on the subject, does anybody see a problem with doing it this way?
