I want a backup software package I can use to store incremental backups I can return to at a certain time in the past. I’ve used back blaze before but it’s free and was wondering if I could backup home dirs incrementally overtime for less or free.

Any alternatives?

Here are a couple of approaches that are a little more technical but flexible:

  • Use rsnapshot, which is based on the standard Linux command rsync but adds incremental backups.
  • Back up onto a a filesystem that supports snapshots, such as ZFS, and create daily snapshots or whatever frequency you want.
  • Use rclone which works with most cloud providers and can be configured for incremental backups (though I haven’t tried it personally for incrementals)

For the rsnapshot and ZFS solutions, you’ll need a local backup drive (say, a USB drive) or a remote Linux server (say, a Linode, which can be as cheap as $5/month) that you configure yourself. For rclone, you can use an account on Dropbox, Google Drive, etc.
