Sorry fo the typo in the subject! Just to add, I would like to see a two way mirror solution, but if it will not work now/is not implemnted yet, I would propably choose between drbd in asynchronous mode or make a some kind if "incremental" snapshot to a remote mapped disk (I do not know yet, if brtfs support it) - it means have one shapshop and let's say have a daily incremental update of this snapshot.
How would you do it? I have never used btrfs, baucause in "brtfs home page" is still written experimental, and lately with three kids I have less and less time to experiment ... but, as I found some short time ago, there is laso a suggestion to use it ... and I know it is used more and more frequently ... so i will give it a try. Btw when is a plan to move it from experimental? ;o) Have to look at the source code a bit (hope there are some notes about future).
