A major tool for that is rsync and rsnapshot.

For general theory about it maybe a google search like:

 linux backup strategy

Well pull up a bunch of likely stuff

If you can give us some more details about what you are looking for
(number of boxes, backup device you want to use, whether you want
simple backup or archiving, etc), you can probably get some better
answers.

My personal favorite for my desktop and laptop is using 'dar' with big
USB hard drives....but that's what works well for me.

I use rdiff-backup, which is ideal for backing up automatically to a
hard drive. I run it from cron, hourly on critical directories, daily on
the rest. I then have a weekly cron script that compresses the backup
directories with squashfs and writes them to ISO images ready for writing
to bootable DVDs. It makes restoring individual files very easy, and a
completely hosed system can be fixed because the DVDs are bootable.

So are my USB hard disks.  Nothing against DVD backups though...I just
find them too slow and small for my needs...

Thanks all for the answers until now;

What i am looking for is to backup 3 servers, and a critical issue workstation.

I have a storage working with samba, so my bakups will go to this
samba server. I would like to make some diff bakups to save storage
space ....

:)

thanks again all of you....

got interested on backups on large USB disks too ...

I think that you should test Bacula. that is very scalable app to backup 
from different sources to different media.

A fair point, although it does make keeping spare, off-site backups
rather expensive :(

rdiff-backup should be excellent with a USB hard disk, I may give it a go.

[OT] how to make Bootable DVD/CDs [Was] Re: [gentoo-user] Backups

how can one create bootable CDs/DVDs? Is there a simple way to transfer
GRUB into the DVD/CDs? Or would "dd" of the /boot partition transfer the
whole thing??

The boot process for a CD is very very different than from a hard
drive.  Basically the BIOS has to pretend that the CD drive is
actually a floppy, or a hard drive, for implementing the BIOS calls
used by the boot loader.  Doing a "dd" of a boot partition and writing
that to a CD would not work.

There are several different software packages that can make bootable
CDs, including GRUB.  Ok, it isn't really GRUB that makes the CD
bootable, but mkisofs.  To use GRUB, you have to make a /boot/grub
directory in your CD tree, and copy the stage2_eltorito file into that
directory along with grub.conf/menu.lst.

Then when you run mkisofs, you add the options:

-b boot/grub/stage2_eltorito -no-emul-boot -boot-load-size 4 -boot-info-table

Someone who uses a GUI for CD burning will have to comment on how to
do this without the command line!

Oh, I forgot one thing.  Instead of (hdX,X) in grub.conf, you use
(cd).  For example:

title 2.6
    kernel (cd)/boot/vmlinuz-2.6 root=/dev/hdc

Of course, your kernel must have support for your CD-ROM drive and the
iso9660 filesystem built in...

The grub info pages contain a whole page about writing bootable CDs and DVDs.

If you get a minute, a detailed wiki howto would be useful for some of
