Rsync or Rdiff

[RoryJMcKenna]

Hello all,

I am putting together a plan for a secondary backup. (Onsite) What I am concidering is either rsync or rdiff. I read the docs on both and they both sound good. What I am looking for is an opinion from someone who has actually used this for incrimental backups... As well as a mirror for redundancy in cause a file server goes down. Any input would be very greatly appreciated.

Also one question, after the initial full backup, is it always just incrimentals? Or do you need to run a full again at any point?

Rsync all the way..

Very easy to set-up as an over the network or machine to machine solution.

Depending on how you run rsync. Rsync updates the files that have been recently edited/updated.

Yes ok.. So at any point you will only keep say a 60 restore window, does this mean when you purge every 60 days you will need a full at that point? Or does it keep the initial seed from the first backup? As I understand it, well with rdiff anyway it is like having a mirror of the drive and within that directory there is an incrimental directory which updates the changes.. This to me would indicate that you would only ever have to do a full once..

You will have to do a main backup once. Let's say your /www.
From there you can set-up rsync on a cron job that runs every 30 minutes and updates the files that have been modified.

Very fast and efficient..
