Backup a linux system?

We have an intranet system running on linux that we want to preserve for a while. The person who developed it left the company. What is the best way to backup this server? So that a hardware fault may arise the system can be restored. Thank you.

Also 'man dump'. Dump it to a separate filesystem.

man dd

dd of=/dev/target if=/dev/source

That will do a binary copy from one device to another.

dd is a bad idea unless the two partitions are *exactly* the same time.

dump is the most reliable linux backup utility.

Mondoarchive might be what you want.

Take a look at dar.

There is also a very nice GUI:

I second the use of dar.  Very nice.

Don't ever use gzip for backing up.  Always use bzip2 if you use anything.  With gzip, a single-bit error makes the rest of your backup useless.

Doesn't bzip2 have the same drawback? If not, why?

Newer versions of Ghost are able to backup both Ext2 and Ext3. If you backup the whole drive it will also grab the boot loader. Ext3 is relatively new, so it's crucial you do test restores to ensure the backups aren't duds. Doing test restores are best practices anyway--even if you don't do Norton Ghost.

Don't they make tivoli backup for linux?

Ext3 is actually quite considerably older than the version of NTFS that ships with Windows XP.  Additionally, you can just treat it as an ext2 file system for backup purposes if you like.

I've found Mondo Rescue to be a good backup solution.  You can create a set of bootable DVDs or CDs that will restore your system from bare metal.  Bit of a learning curve, though.

rsnapshot!

It makes backup and recovery extremely easy, especially to an external hard-disk (or a remote location).

Check out: http://www.rsnapshot.org

You can also check out BACULA. [ http://www.bacula.org ]

It's a network back-up system, which is very powerfull and can do mixed (windows - linux - mac) environments as well IIRC.
