I've been testing TDB for a while, and am very impressed with its performance. However, I do see the various emails on the mailing lists warning of touching the files while an application with TDB is open (presumably with an open Jena Model attached to the TDB directory).
What kind of reliability does TDB have to survive a power hit or application crash? Are there some steps to take consistent and regular backups to mitigate any issues? Basically looking to have some level of confidence that I can use TDB in production, take a reasonable amount of steps to insure reliability, and be confident that I'll always either have a valid TDB store, or a way to incrementally backup/rollback in the case of a severe crash/file system error.
