Apple has identified an “issue” with Time Machine corrupting the Aperture database. Ouch. Since both programs are made by Apple, you’d think they would have figured that one out already.
Apple Explains:
Issue or symptom
Running Time Machine backup or restore operations while Aperture is running may lead to inconsistencies in the Aperture database.
Products affected
Aperture
Mac OS X 10.5 Leopard
Solution
If you use Time Machine with Leopard, be sure to set your computer up so that Time Machine only does manual backups. Avoid performing either backups or restores while Aperture is running.
