From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm using
rustic
, a lock-free rust-written drop-in-replacement ofrestic
, which (I'm referring torestic
and therefore in extension torustic
) supports always-encrypted, deduplicating, compressed and easy backups without you needing to worry about whether to do a full- or incremental-backup.All my machines run hourly backups of all mounted partitions to an append-only repo at borgbase. I have a file with ignore pattern globs to skip unwanted files and dirs (i.e.:
**/.cache
).While I think borgbase is ok, ther're just using hetzner storage boxes in the background, which are cheaper if you use them directly. I'm thinking of migrating my backups to a handfull of homelabs from trusted friends and family instead.
The backups have a randomized delay of 5m and typically take about 8-9s each (unless big new files need to be uploaded). They are triggered by persistent systemd-timers.
The backups have been running across my laptop, pc and server for about 6 months now and I'm at ~380 GiB storage usage total.
I've mounted backup snapshots on multiple occasions already to either get an old version of a file, or restore it entirely.
There is a tool called
redu
which is likencdu
but works onrestic
/rustic
repos. This makes it easy to identify which files blow up your backup size.This is the correct way. I wish hetzner had a storage box size between the 1TB and 5TB version though.
