I have a shell script that i'll be running with a crontab. Basically I want to modify this so I can do daily backups for the last 3 days. I've seen examples where the last 7 days are backup. I just need the last 3 rolling days. I know I would have to do a separate script for the weekly schedule.

code:

rsync -avzh --delete XXXX@XXXXX:/home/XXXXX/source/ /$HOME/destination

Any help is greatly appreciated.

Someone has already written a script that does this, and it has a lot of great features, plus it has been tested by many people for years. It is called "rsnapshot".

I highly recommend "rsnapshot". It is easy to configure and will do a 3-day retention, or even more complex retention policies.

  • I will investigate on this. So that means that you can't do this with rsync? will rsnapshot work with crontab? – Rene Merino Jun 18 '14 at 20:19
  • To be clear, rsnapshot is just a script that calls rsync. It just does all the complexities of expiring old snapshots for you. – TomOnTime Jun 18 '14 at 20:21
  • I see, does this work on ubuntu? is not listed in their website – Rene Merino Jun 18 '14 at 20:22
  • @ReneMerino It works perfectly fine on Debian, which is still pretty close to Ubuntu. Why don't you try it yourself? Just use a smaller dataset if you want to speed things up while you're testing. – user Jun 18 '14 at 20:24
  • I installed it in my server, I hope this works - Thanks @TomOnTime – Rene Merino Jun 18 '14 at 20:24

Maybe you also want to take a look at http://backuppc.sourceforge.net/

It's more than just a script, it's a server side solution for backing up multiple servers. Maybe a bit too much for you, but also very popular.
