I'm looking for a solution that can encrypt AND sync targeted drives/folders in one go. What I am trying to accomplish is that I have an encrypted partition (currently using Truecrypt, but any other solution will do) which I store my private files. I also have another computer at a remote site with a copy of this encrypted drive which I need to keep in sync with very few efforts.
Cloud storage is not an option in my country where the internet is extremely slow and expensive. So I have to use external HDDs to directly copy the files.
Backup software with encryption is also not an option because two persons could potentially work on both computers simultaneously and then the file changes needs to be synced.
All sync apps that I have tried exposes my private files on the external HDD with no encryption.
I could install Truecrypt on the external HDD too, but to open each Truecrypt volume (re-entering the password), sync files, remember to close the correct Truecrypt volumes are a very cumbersome task.
Are there any tools out there that would make the task of synchronizing the two computer's files using external HDD's easy and safe?
