+A simple tool for backups is [rsync](https://rsync.samba.org/) that copies files from a host to another, and which files can be archived or not, and checks if a file has been modified, or is removed or created, and updates the backup target repository accordingly. But it doesn't create snapshots and thus we cannot access the state of a system's files of a specific date in the past. Dedicated backup tools create snapshots and retain a history of the changes, so we can choose what version to restore. However we need to keep track of the backup's disk storage and remove older snapshots on a regular basis.
