Bill Cheeseman brought up what looks like a potential problem that all Aperture users wanting to use the Time Machine feature in Leopard should be aware of. I don’t think any of us want to take any chances with our libraries. I wondered how Time Machine might work with managed Aperture Libraries, using Vaults to back up. I think much more on this will come to light in the next few days and weeks and perhaps a final solution will come with the next update of Aperture. But in the meantime, let’s be careful out there.
“Issue or symptom
Running Time Machine backup or restore operations while Aperture is running may lead to inconsistencies in the Aperture database.
Mac OS X 10.5 Leopard
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.
This document will be updated as more information becomes available.”
