For my personal stuff I have a seafile server on a vps. I have 'full history' turned on, which essentially gives me snapshots of every uploaded change of every file, browsable by individual file or by date and time for the whole backup space. For work stuff, I've been loving borg-backup. Others here have mentioned why it's superior. I agree. Once they get support for remote object stores like S3, it will be hands down the best backup solution: https://github.com/borgbackup/borg/issues/102 https://github.com/borgbackup/borg/issues/102. Even though, there is a fuse layer for S3 that may work (haven't tried that yet).
