Oops. sorry I accidentally sent the email. So, I have several laptops and a desktop that I would like to back up and keep in sync. * Every client (laptop) is encrypted with cryptsetup and LUKS * There are different configuration and big image files that I would like to back up from each device but not synchronize * I can host my own server * I would prefer to store encrypted backup on a cryptsetup and LUKS partition * I would like to periodically sync encrypted backup partition to s3/google drive with minimal overhead * I only want to mount encrypted backup partition when sync/backup is in progress and I'm fine with mounting that backup partition with the keys stored on the client machines in clear text * I don't have to have web interface or * I need to automatically do file sync backup for the clients, preferably based on network location (i.e. when I'm close to backup server, or connected with a fast link). I'm thinking of clobbering something together with a bunch of scripts, but my guess is this problem has been either completely solve, or I can just use a few big pieces to solve it. Could you recommend any tools for that? Thanks, Alex.
