I have my home folder with a few GB.

Is it possible to run tar on it, create a home.tar.gz, and then for changed files, it creates home1.tar.gz only with modified files from previous tar (thus being an incremental backup)?

I would like to check the resulting checksum files and export them as well like home.md5, home1.md5, etc. (I know this could be another process, but interesting as well).
