This is a 2026 map of the open source backup ecosystem: Restic, BorgBackup, Kopia, Duplicati, rclone, Bacula/Bareos, Amanda, UrBackup, Velero, Kasten, pgBackRest, WAL-G, Time Machine, ZFS/Btrfs snapshots, LTO tape, B2 / Wasabi / Storj cold storage, and Veeam alternatives. The 3-2-1 rule, the modern 3-2-1-1-0 variant, full/incremental/differential/synthetic-full backup types, encryption and verification, and the most common pitfall — the untested restore.
