David, your advice to back up data regularly is good, but rsync'ing from one array to another is not the same as backing up. I don't know how often you rsync, but right after you do, you can't restore a file you accidentally deleted or clobbered yesterday. At most you have one previous version of the dataset available.
Rsync with --backup-dir=/incremental/2013-08-04:16:00 or similar gives you incremental data though. I.e. one live version of the latest data and then incremental diffs date-by-date.
Or you can use snapshots if the backup system supports them and you prefer your data that way.
Which option you prefer depends on intended usage -- snapshots are probably better when files get renamed (rsync will make a copy of the data, snapshots will not) but rsync lets you delete individual files from the backup while keeping others, which you can't so easily do with non-editable snapshots.
