It depends. Dump makes an image of a file system. While this is a
belt-and-braces approach (i.e. you can be certain that file metadata,
extended attributes, deleted files etc are backed up), it's often viewed
as inefficient. What if, for example, you want to use the back up to
migrate to a different file system. What if you want a more
space-efficient backup (do you REALLY need to dump those hundreds of
gigabytes of empty space?).

A file-based backup is generally preferred. I can't speak for
luckybackup, but a good file-based backup system should back up all your
files. It should also handle xattrs, acls etc if those are important to
you.

In theory, the files are all you really need for a backup. To restore
for bare metal, you would partition the disks as appropriate, restore
the latest backup, re-install the bootloader (as the MBR is typically
not included in a file-based backup) and reboot.

I use mondorescue to backup a Debian partition to DVD and that DVD can be booted to be restored anywhere.

Some users usually do combine both: daily backups to save the most
important data and full image cloning/snapshots for the whole system
mostly for recovery or (mass)installation purposes.

Obviously, cloning the whole system takes more time and resources, you
have to choose what combo approach fits better for you.

I use partimage cl command to make images of your partitions and should be
available in debian. Work very well, also compresses the file.

What *exactly* do you want to backup? /home? / ? You need to be
specific, and you also need to decide on what you want to back up to.

I backup my /home to an external USB h/d every 3 hours, and the
scripts I use can be seen in the most recent post of my blog.

Take care
Sharon.

I use rsync on all Linux/Unix platforms. I have little shell scripts set
up so I don't have to remember every little command switch every time.


I generally rsync to a USB-connected hard drive.

Rsync is well worth learning and using.

My vote is for rdiff-backup http://www.nongnu.org/rdiff-backup/ It is
the same as rsync but it keeps the diffs of old backups.

It stores the incremental differences (like SVN or GIT). Therefore you
can restore a document as it was in a previous backup. I find that the
best is to do incremental backups. How about you delete a file, do
your backup... and then realized that the file that you deleted is
important! but you can not find it anymore in your backup because you
did a rsync...

You can find rsync and rdiff-backup in any distribution. But rsync is
way more common
