Creative Cloud file sync deleting local files when they shouldn't

Hi all,

I've just had a bit of a scare and I want to confirm if this going to be a potentially future problem for me - and if so what's the best way to deal with it.

I have signed up for the File Sync feature in CC and it seemed to be working well. Thus far it has...

a) saved me the need to manually transfer my current work files from my iMac to Macbook when going out to see clients, and

b) given me an additional form of backup in the event of a major hardware issue

Every month I backup all my files to 2 external hard drives, plus keep a copy of all files locally on my iMac - removing from my current folder all the jobs that have been finalised.

I just was doing my standard backup procedure now and noticed one of my finalised job folders with no files in them but the folder structure still there. I then had a search through all my other job folders and found another client folder with my InDesign files gone but the linked image files still there.

Thank goodness Mac's Time Machine bailed me out and I was able to restore those files and then include them in my monthly backup.

This freaks me out because I'm not that dumb to delete files like these myself - I know my process and it works. The only conclusion I can think of is possibly the cloud chose to delete the files for some inexplicable reason?

Is there anyone out there who's had the same thing happen? Was there some error that I've possibly overlooked? If an Adobe rep could chip in that would be greatly appreciated.

Cheers,

Andrew
