how do you Backup your system?
I use BTRBK to make and copy BTRFS snapshots to my HDD. I schedule it to run every 3 hours using a Sytemd unit file through my own script to run the backup at more convenient moments:

How can I send audio output to multiple bluetooth devices?
I personally prefer to use the old module-combine-sink module due to its simplicity. It's rock solid. I use it for about two years with this script I made. Don't think too much about it, since it's implemented in a quite different scenario from what you have there. The only similarity is that we are creating a virtual sink to simultaneously output sound from two different sinks. I have a mini-system that I keep disabled and the script not only creates the virtual sink but also enables the mini-system sink. For everyday use, I prefer to keep my audio panel clean with just my HDMI sink.

Do I need to do anything specific after a PC freeze?
Having some concern is one thing, thinking of doing intensive disk procedures is a whole 'nother story. I mean.. It's just a cold shutdown. Anyway, if you're copying some data for the first time and a cold shutdown happens, there's nowhere to run on any filesystem. The data would be obviously gone. I never had a single issue after some cold shutdown and I have a script that periodically checks its health. On COW filesystems, the data is presented on the disk just once, even if you copy it, for example. On further manipulation of that data, that change it's written in one or more unused blocks, and the original data remains unchanged. If some unexpected shutdown strikes, for example, the original data will be safe where it was before.

Wayland users, how is waydroid? Does it actually support all android apps natively?
Just for you to know, you can use Wayland under Xorg as well. What prevents me to use it nowadays is the fact it doesn't support webcam, so I'm using Android through QEMU. I made a script for it that passes my webcam. It just works.
-
Expose QEMU/libvirt port to LAN?
I'm setting up my network every time I start the VM like this using a bridge. My VM is behind the android_bridge0 bridge using NAT. In this case, I don't need to use port forward.
-
Is there a way to control the battery level on Android running through QEMU?
I have this script to set up the environment and load my Android VM. It's working perfectly with camera, sound, 3D accel and all, but the battery it's always at its minimum, which some apps refuse to work with.

How to shorten repetitive parts of a script?
Now (I already cut the number of lines in half)

Weird makedep segmentation fault when './configure'ing Wine source
Just bumping the version is the simplest case possible, but sadly, TKG has around 750 patches, and what's going to be applied highly depends on the version and my config. In fact, that's one of the reasons they didn't make an ebuild yet.

What are your favorite non-GUI/DE customizations?
I made four so far.(starting wit taskbar_)
-
Is there any other widget that prints the output of a command or script besides CommandOutput and Kargos?

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:
