I accidentally programmed my server to back up all files... even backups
That's still easier using snapshots and something like btrbk. Snapshot the directory at start, prune if there are too many snapshots (or snapshots get too old).

Ur best backup software
I'm on Arch, but you might still find it useful: Btrfs snapshots Arch Wiki - Incremental backup to external drive GitHub - btrbk
- Deduplication how to?

Fast and comprehensive system backup. Can Linux software do it?
the smoothest backup tool i have seen for Linux is btrbk works real nice and is customizable for almost all use-cases BTRFS rocks :)

Trying to understand the real impact of not having ECC
I recommend redundancy and regular verification is you want to insure your data against corruption. If you do that, you can forget about things like ECC. My setup is a NUC server running Ubuntu with a USB3-connected storage drive running BTRFS. I use btrbk to auto-snapshot and auto-replicate via incremental sends to my BTRFS backup drive, and RotKraken to track integrity of the data with a monthly verification run so that I notice corruption in time to correct it.

BTRFS snapshots and btrbk as a backup solution
In pondering my backup strategy, I was wondering if I could use BTRFS snapshots and a backup tool like btrbk, which is a nice integrated snapshot/backup solution I've used happily on desktop Linux. BTRFS needs subvolumes for snapshots, so I couldn't backup the host itself (which wasn't installed with a / subvolume like other distributions I've used), but it could snapshot the VMs and containers, which have their own individual subvolumes. Then btrbk can send that snapshot in an incremental fashion to external storage.
-
btrbk: subvolume has no UUID error
I then installed btrbk and tried to follow the instructions to create snapshots of root and home on the SSD and then send/receive those to the HDD. I mainly used https://github.com/digint/btrbk and https://mutschler.dev/linux/fedora-btrfs-35/, but I don't use luks.

The various scripts I use to back up my home computers using SSH and rsync
For anyone using btrfs on their system, I heartily recommend btrbk, which has served me very well for making incremental backups with a customizable retention period: https://github.com/digint/btrbk

incremental snapshot backup tool: which one should i go for?
btrbk is the best solution I know.
-
how do you Backup your system?
I use BTRBK to make and copy the BTRFS snapshots to my HDD. I schedule it to run every 3 hours using a Sytemd unit file through my own script to avoid running the backup at inconvenient moments:

Arch simply has never failed me (gamer)
Afaik the proper solution is to use https://github.com/Antynea/grub-btrfs/blob/master/initramfs/readme.md and/or rollback the root to a snapshot.

BTRFS restore question ā newb, be gentle
Something I noticed is that the instructions here before step 2 suggest that the files /etc/initcpio/install/grub-btrfs-overlayfs and /etc/initcpio/hooks/grub-btrfs-overlayfs might exist, and they don't for me. Worth noting that I installed through pacman, which may be a reason they don't exist if I'm reading those instructions correctly.

How to replicate SpiralLinux snapshot + rollback in plain debian?
In Debian, I see that there is a custom installer "Spiral Linux" (https://spirallinux.github.io) with non-default settings that achieves the same kind of mechanism using "grub-btrfs" (https://github.com/Antynea/grub-btrfs) in combination with "snapper-rollback" (https://github.com/jrabinow/snapper-rollback) and a BTRFS subvolume layout suggested by the Arch wiki (https://wiki.archlinux.org/index.php/Snapper#Suggested_filesystem_layout).

Kali unkaputtbar/snapper not appearing on grub
When the issue first arrived (around 01/11/2023, IIRC), I did try posting an "Issue" on the GitHub page for grub-btrfs (located here), & more specifically on Issue #254, however, for whatever reason (at that time) I wasn't able to make a post on that Issue/forum.
What are some alternatives?
snapper-gui - GUI for snapper, a tool for Linux filesystem snapshot management, works with btrfs, ext4 and thin-provisioned LVM volumes
timeshift-autosnap-apt - Timeshift auto-snapshot script for Ubuntu and Debian based systems which creates snapshots of your system with timeshift before a package install, remove or upgrade using DPkg::Pre-Invoke hook in apt. Fork of timeshift-autosnap from AUR.
TimeShift - System restore tool for Linux. Creates filesystem snapshots using rsync+hardlinks, or BTRFS snapshots. Supports scheduled snapshots, multiple backup levels, and exclude filters. Snapshots can be restored while system is running or from Live CD/USB.
