To PG it just looks like the power went out or some other failure. It'll replay parts of its log and be on its merry way. This is *much* faster than using pg_dump / pg_restore, especially on huge db's. If you are using xfs you may want to wrap the snapshot call with xfs_freeze/unfreeze. It may also be nice every once in a while to do a normal pg_dump.. -- Jeff Trout <[EMAIL PROTECTED]> http://www.jefftrout.com/ http://www.stuarthamm.net/ ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
