A good way how to backup user data in CentOS?

I need to back up my data and I have not found a good way so far. Just say I have 1 TB of a non-system disk with 50-100 GB of user data (binary files, source code, images, etc.). And another big disk, where I could save backups. I could use rsync or just cp, but I think it is not what I want. I want an incremental backup. Restore a file/folder/whole drive from some point in time. Load a backup from some point in time to another disk (copy or just open read-only). See changes between backups and add an optional comment would be nice. Does anybody know a good cli backup tool? Maybe some snapshots tools? Or a git? But git for 50 GB of user data; isn't it nonsense? :D
