Conflict between Time Machine and Sugarsync

Hi everyone,

I was checking the integrity of my Time Machine backups for my differents macs and realized that some folders synced to SugarSync aren't backep up properly by Time Machine.

I've been able to replicate this problem on 4 different macs running 10.7.2 and the latest build of Sugarsync for Mac.

What happens is:

Initial Time Machine backup works fine. Incremental time machine backups work for some time and after a while changes in synced folders aren't updated in Time Machine backups although they are replicated in Sugarsync and amongst my computers through Sugarsync (but not on the Time Machine backups of the computers).

This is happening on my 4 Macs. I have another Mac where Sugarsync isn't installed which is not affected by this problem.

The only common factor between all these macs is Sugarsync.

As this problem is not easy to replicate, I invite all users using Time Machine to check their backups for missing files.

My main concern is that Time Machine seems to be running well, there are no error messages but it does not back up some files as if it did not "see" the changes that occured in synced folders.

I've already tried to reset the time machine backups and restart from scratch but this problem keeps re-occuring.
