The thing to watch out for with backup is how it affects the normal
working set of the nodes in the cluster. Often you'll get much better
performance with backup if you write a custom set of scripts which
respects the working set on each node and which also allows the backup
to proceed in parallel across the filesystem.

What makes a good backup solution depends on the application and the I/O
pattern, so it is tricky to make any generic suggestions,

Steve.
