Hi,

Ok, this is a tough one, and it might not even be possible, but no harm in asking I guess.

I have a Buffalo Terastation file server that I use for network attached storage. After a couple of phone calls to customer services I realised that there is no way to backup to disk encrypted. In effect, I would be carrying unencrypted company data off-site daily, which is obviously unacceptable.

I had a go at TrueCrypt, EncFS, and a few others, and as far as I could see all of them required that you install some software on the machine that is to use the file system, which makes sense. Unfortunately the firmware on the Terastation is closed and I cannot install any software (and I can't build from source either, since Buffalo didn't include a compiler).

Are there any ways to copy files to disk, where as soon as they are written to the disk they are transparently encrypted, without having to install additional software?

I'm not sure it matters too much, but the Terastation firmware is Linux based, although as I mentioned, closed.

Many thanks,

Andreas
