A chunk-store backup that was projected to take ten days for sixty six gigabytes. The protocol was CIFS over rsync. The fix was rclone over SFTP with parallel transfers. The same data, the same network, the same off-site target, moved 280 times faster. The reason is a protocol property that does not show up in any "which backup software" comparison but that decides whether your backup can actually finish before tomorrow.

ext4 will hand you a corrupted file and swear everything is fine. ZFS checksums every block, repairs what it can, and makes snapshots cost nothing. With ZoL 0.7 out and Stretch a contrib package away from it, here is why my homelab storage now runs on copy-on-write, and the licensing mess you sign up for by using it.
Borg 1.0 has been stable since February. If your backup strategy is still rsync to an external drive, you are leaving real safety on the table. Encryption, deduplication, and compression are not optional anymore.
