Vault not backing up
Hi, I've created a vault for one of my image libraries. The library is large (300Gb) though the vault is less than 300Mb. There are no referenced images in the library and I've done a double check on this by searching for referenced images. ANy thoughts on what's happening? I want to ensure my images are backed up but this isn't giving me much comfort that they are! (I'm on Aperture 3.2.2).
Thanks.
