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.

Can you please share your backup strategies for linux? I'm curious to know what tools you use and why?How do you automate/schedule backups? Which files/folders you back up? What is your prefered hardware/cloud storage and how do you manage storage space?

I leverage btrfs or ZFS snapshots. I take rolling system level snapshots on a schedule (daily, weekly, monthly and separately before any package upgrades or installs) and user data snapshots every couple of hours. Then I use btrbk to sync those snapshots to an external drive at least once a week. When I have all of my networking gear and home services setup I also sync all of this to storage on my NAS. Any hosts on the network keep rolling snapshots stored on the NAS as well.

Important data also gets shoveled into a B2 bucket and/or Google drive if I need to be able to access it from a phone.

I keep snapshots small by splitting data up into well defined subvolumes, anything that can be reacquired from the cloud (downloads, package caches, steam libraries, movies, music, etc) isn't included in the backup strategy. If I download something and it's hard to find or important I move it out of downloads and into a location that is covered by my backups.
