What I've been using on windows is truecrypt to encrypt the drive and 1) unison + gui frontend to do a quick backup of selected files & 2) a bat file that calls xcopy to copy files with the archive flag set to YYMMDD/ on an encrypted drive (ie. an incremental backup; I do a full backup every few months)
Luckily, you can use almost the exact same tools for achieving the same on Debian. There are a few choices for the encryption tool you use; I suggest using "cryptsetup", especially over a few of the alternatives (encfs, ecryptfs) but the tooling you use to achieve this will depend upon what desktop environment (if any) you are using. I know that GNOME 3 (what I'm using) can detect and mount LUKS-encrypted disks when they are attached to my machine. What I'm not sure about is whether it can be used to create those in the first place. Although I guess that's a one-time operation (per external USB), so not too bad to do it via command-line tools. See man cryptsetup(1) <https://manpages.debian.org/stretch/cryptsetup-bin/cryptsetup.8.en.html> Once you've got the encrypted disk set up, you could use unison similarly to how you are on Windows. You'd need to re-implement the batch file if you wanted exactly the same behaviour for that, and there's no direct analogue of the archive bit that I can think of, so marking/identifying files is one part of the puzzle; I'd recommend taking a look at rsync for performing the copy. Or throw it all out and use something like rdiff-backup and just back up everything… -- ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Jonathan Dowland ⢿⡄⠘⠷⠚⠋⠀ https://jmtd.net ⠈⠳⣄⠀⠀⠀⠀ Please do not CC me, I am subscribed to the list.
