  • BorgBackup

    Deduplicating archiver with compression and authenticated encryption.

    If these files are archived files that you don't use or access frequently you could use borg backup. It is like git but it works with binary data/all types of data, so you can keep a versioned history of your files and the archive will only grow by the size of the new data added. Also provides compression. I use this for versioned backups of stuff like Minecraft saves, virtual machines, etc.
