>I would simply use the equivalent of rsync -Pa /ramdisk /disk in a loop That's probably a bad idea. rsync isn't going to copy over writes in the same order they were written by the DB. Most DBs assume that when there's some crash that at least the disk would have been in a logically consistent state with respect to the order of certain writes separated by e.g. fsync and barriers.
