image backing up a linux machine


hi guys,

i know there are many tools/commands to back up a linux machine

was just reading about dd clonezilla etc

the downside to these is that they do a full image every time which wastes time and works the metal a bit hard.would be nice if there was a program/utility similar to backup on windows server which takes a snap shot and then only adds the changed/added files to the backup everyday after.

has anybody got any suggestions regarding this and linux?

thanks

what i did with a 10 year old server:
1-clone the server with CloneZilla
2-restore the server to a VM
3-backup only the partition or directory which holds the data

Now I can move the VM anywhere, anytime and just restore the backup that holds the current data.

Hope you get an idea. Cheers..

Amanda, Bakula, and probably more.
As mentioned, rsync is also able to make incremental backups.

I would say that, roughly, Clonezilla, dd and other cloning tools are good for disaster recovery, especially if you combine them with an incremental tool.
File-by-file backup tools like rsync, Amanda etc are good for restoring files that you deleted or overwrote by mistake.
And there is a large overlap between the two.

Do you want it automated?
Do you have a need for live state backups like windows? (you can't get that for free as of yet that I know of)
Do you have your data in any logical spot of do you want to have the entire file system searched for files.
Can you use one of the advanced filesystems like btrfs?
Can you use old tools like tar?

Look at this list too. http://www.linuxlinks.com/article/20...03/Backup.html

I use rsnapshot and it's worked very well for me.
It's essentially incremental, automated rsync.
