Hard to vote only once as Clonezilla, rsync, mysqldump, and tar are all used in specific cases. Each has it's task in saving my butt.

I voted for AMANDA. It just keeps on working even when things like pieces of the network or the tape drive temporarily fail. It works things out on its own without the need for intervention (rather than just stopping/failing and waiting for me to do something), and then catches up on the failed pieces on its own after I have gotten them back online.

I also use rsync all the time. There are cases where rsync runs on cron and AMANDA picks up the copy from the local server and puts it on tape (currently LTO6 in a library with a 22 tape rotation).

I'm a firm believer in redundancy in backups.

Maybe these are only opensource. Not voting because I do not see (a product) I would look at first, before any of these - as they are the people who designed/authored the product I use now. So, assuming noone else has mentioned it already - what I miss in the list is "Storix" - and what I use is mksysb/savevg (part of AIX).

However, glad to see the list as it helps me know where the "Linux" world/community looks for it's backup solutions.

AMANDA. I've used it at multiple jobs dating back two decades and currently use it to manage nightly backups for 77 individual file systems spread across our corporate network. It is now offered with an Enterprise version that is fully supported, if the very word "opensource" scares your PHB.

Why not add Grsync to the list?

tar -cf /media/usb/backup.tar /home

(using one of three external hard drives, so I'm not overwriting my only backup.)

Timeshift!

One that really should be on there is Duplicati (different from Duplicity):

http://www.duplicati.com/

FOSS and cross-platform. Multiple backup methods and advanced configuration adjustments, but with decent GUI interface.

I would have chosen GRsync but that was not there so chose rsync instead.

Grsync isn't really a backup application it's just a gui front end to rsync.

FreeFileSync for me - a nifty GUI backup program.
