Wrote a hacky bash script using LTOEnc (a windows cli tool for setting up LTO hardware encryption) and tar to backup my PC. (Using Cygwin)

But I'm confused with `tar -b`. With larger blocking factor, each record get bigger but when dealing small files there are more space wasted. I'm backing up both C and D drive, where D drive lives my code and movies/animes/shows.

Don't want to be too extrem on parameters, so I use `-b 1024` and enabled compression to make balance.

Also enabled encryption. While I don't want to encrypt long time archive, backup is a more short term thing, which I'm pretty sure I won't forget the password.

Should be fine I guess? Now I'm testing it.
