Spoofing files to Crashplan/Backblaze

Tue Feb 11, 2014 10:18 am

My storage drive is starting to make strange sounds, though SMART says all is good, but in general, I really need to get a backup.

One solution is building a cheap NAS, but that doesn't protect me in case of a burglary, and I'd rather just keep adding harddrives to my always on PC, and use that as a NAS.

The problem is that not all my files are legal, it could be a movie I have downloaded, or some music, it doesn't matter. What matters is that although the data is encrypted via Crashplan, the hash value can, and likely is, compared against copies of known illegal files.

I wish my backups to be made in such a way that the hash value turns out different at the end of Crashplan, even though they might have an identical copy the same file, and thus can deduce what it is.

Truecrypt wouldn't work I think, because Truecrypt would decrypt on the fly, before transmitting to Crashplan.

Any ideas?


I considered building a cheap NAS, backing up to that in encrypted form, and then having that backed up to Crashplan. That would change the Hash values. But, kinda, I am on an extreme budget right now. So though a fun project, maybe later.
