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?

Synology NAS. I really love that thing. I use their synology drive software to backup the Linux home folder, as well as windows PCs, iPads, iPhones etc. I use their photos mobile software to automatically backup phone photos and videos. I also synchronize a few select folders between PCs so certain in-use files are always up to date. I set the NAS to keep 30 old versions of every file. This works great for my college kids - dad has a copy of everything in case they nuke a paper or something (which has happened).

I stopped cloning drives long ago. Now I just reinstall the os and packages. With Linux, this is honestly faster than deploying a backup - a single pacman command installs everything I want. Then I just log into things as I open them. Ya I might have to futz around with some settings or redownload some big games on steam - but the eye candy and games can wait - I can be productive pretty quickly after an install.

I DO use btrfs with automatic snapshots (snapper and btrfs assistant). This saves me from myself when I bork an update (which I’ve done more than once). If I make a mistake, I just rollback a snapshot, and try again without my stupid mistakes. This has saved my install 3 or 4 times now.

Lastly, I sneaker net an external hard drive to my office. On it is a manual backup of the NAS. I do this once per month. This protects from catastrophic failures like my house burning down. I might lose a month or so of pictures in the worst case scenario, but I still have my 25+ years of pictures of my kids, wedding videos, etc.

In the end, the only thing that really matters is not losing my lifetime of family pictures and the good memories they provoke.

Synology NAS here also, divided into private (family stuff, docker volumes etc) and public (Linux ISOs and anything that can be redownloaded). Both get backed up weekly to an older NAS with Hyper Backup. Private additionally goes onto a LUKS encrypted drive monthly which is spot-checked, taken offsite, and the previous offsite drive brought back. I don't back up any PC (don't care, just reinstall) or phones (they are backed up on iCloud).
