Aperture, OS X 10.5.2 and Time Machine

[Scott Lewis]

I've noticed that 10.5.2's new "Aperture" support in Time Machine  
seems limited to backing up the Aperture Vault once per 24 hour  
period... which tells me they haven't sold the problem of detecting  
changes within the library, but just worked around it to avoid the  
potential problem of having the entire vault backed up as often as an  
hour, which can waste (in my case) dozens and dozens of gigabytes PER  
BACKUP.

Has anybody else noticed this? I hadn't seen it covered, only seen  
reference to "Aperture being supported in 10.5.2". While Aperture has  
strong control over image editing, and things can be undone easily,  
this is poor protection for my actual images, since rather than  
waiting no more than 59 minutes for a backup, I have to wait as much  
as 23 hours and 59 minutes!

I guess I'll continue my practice of backing up Aperture to another  
vault every time I finish uploading images. It's just a shame, because  
from what I can tell, the original images are never touched inside the  
vault bundle, only a file that is very small (average 4k) that I guess  
contains a list of edits I've made such as Contrast +4 etc.

Anybody have any idea why this is so infinitely harder for Apple to  
backup via Time Machine than an iPhoto Library?
