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.

How do you all go about backing up your data, on Linux? (self.linux)

I'm trying to find a good method of making periodic, incremental backups. I assume that the most minimal approach would be to have a Cronjob run rsync periodically, but I'm curious what other solutions may exist.

I'm interested in both command-line, and GUI solutions.

ZFS send / recieve and snapshots.

Does this method allow to pick what you need to backup or it's the entire filesystem?

It allows me to copy select datasets inside the pool.

So I can choose rpool/USERDATA/so-n-so_123xu4 for user so-n-so. I can also choose copy copy some or all of the rpool/ROOT/ubuntu_abcdef, and it's nested datasets.

I settle for backing up users and rpool/ROOT/ubuntu_abcdef, ignoring the stuff in var datasets. This gets me my users home, roots home, /opt. Tis all I need. I have snapshots and mirrored m2 ssd's for handling most other problems (which I've not yet had).

The only bugger is /boot (on bpool). Kernel updates grown in there and fill it up, even if you remove them via apt... because snapshots. So I have to be careful to clean it's snapshots.
