Subject Re: FileDataStore vs DatabaseDataStore
Date Mon, 21 Sep 2009 09:10:33 GMT

I have extended the wiki a bit: http://wiki.apache.org/jackrabbit/DataStore

"Because the data store is append-only, the FileDataStore is
guaranteed to be consistent after a crash (unlike the
BundleFsPersistenceManager). It is usually faster than the database
data store, and the preferred choice unless you have strict
operational reasons to put everything into a database."

No, but "currently this can be done manually moving directories to
different disks and by creating softlinks"

> point in time recovery

The data store is append-only and does not "need" point-in-time
recovery. Just restore all files you find :-) To free up disk space
run the data store garbage collection.
