Attic walks through your files, splits the data into chunks, compresses them, encrypts them (if you want), and stores only the pieces it hasn’t already seen. When you run it again, it skips over what hasn’t changed. So, every backup looks like a full snapshot — but under the hood, it’s mostly just the deltas.

Let’s say you’re managing a bunch of machines — Linux here, some Windows there, maybe a few Macs in the mix. You don’t want agents on every box. You don’t want to deal with yet another cloud panel or be tied to a proprietary system. You just want backups that work, stay out of the way, and don’t eat up all your storage. That’s where BackupPC fits.

Backups usually fall into two camps — bloated tools with pretty dashboards, or spartan ones that feel like half-finished academic projects. Kopia lands in that rare middle ground: simple, open-source, no fluff… and surprisingly good.

Some tools try to do everything. BorgBackup doesn’t. It focuses on one thing — backing up your data safely and efficiently — and does it extremely well. No cloud ties, no mystery layers, no nagging GUIs. Just a command-line interface, strong encryption, and solid, repeatable behavior.
