Backup to Vault Fails Before Switching From Copying Masters to Next Step

Question

My backup to a Vault in Aperture 3 has failed.
I have successfully upgraded to Aperture 3 from Aperture 2. Everything works well, except backing up to a Vault. I have attempted to save the entire library to two different drives - one internal and one external, both empty and tested as OK in the Disk Utility. The backups - multiple times - simply stopped at the same place. The usual sequence is copying masters and then versions, but the full backups never went beyond copying masters. I’ve set up additional libraries of individual projects, and those libraries backed up to vaults with no problem. I had no problems with saving to a Vault with the Aperture 2 library.
I’m using a Mac Pro with Snow Leopard (10.6.2), 2x2.66 Dual-Core Intel Xeons, and 10gb of memory. There are four internal drives, and two external drives connected by a firewire connection. The computer and drives are unchanged through the transition to Aperture 3.
Any suggestions?

Answer 1

I Have exact the same problem.
Originally updated a 150 GB Library from 2.1.4 to Ap 3; Backing up to a NAS based Vault stops after doing the masters.
I ended in reinstalling Ap 3, and Creating a new library from scratch. Reimporting the upgraded library worked fine, but Vault freezes like before.
Creating gain a new library and Importing original masters and versions step by step. After every import Vault backup works until now (60% done).
I m curious wether it will work when I m finished.
All my keywording etc. will be gone then !
