I've been using restic for a long time now. It's flexibility is amazing: * Fully open-source, command line implementation. Script as needed. * Supports ton of backends, including directories, SFTP, and many cloud services. * Supports multiple backup operations in parallel. Create one repo for multiple machines. * A repo is really an encrypted object store with a lists of directory/file/metadata references (snapshots). If the same file exists on multiple directories/drives/machines, it is deduplicated. * Supports tagging, which allow you to identify independent snapshots and manage them. * Supports purging old data with conditions, ie. keep last 7 daily, 3 weekly, and 6 monthly. * Can verify and repair repositories. I regularly use it to backup my home server to a backup drive and to Backblaze. I've also used to back up my home directory of my development machine to replicate it on another machine.
