I just mention the very basic, Btrfs has way to many features and options to make a generic image creating script. I see already 2 issues in the shrink-backup scrip, simple test: root@rock5b:~ # btrfs filesystem du -s --raw / Total Exclusive Set shared Filename ERROR: not a btrfs filesystem: /boot/efi WARNING: cannot access 'efi': Invalid argument WARNING: cannot access 'boot': Invalid argument ERROR: cannot check space of '/': Invalid argument This is on Opensuse Tumbleweed, but distro should not matter as I have a custom simple subvolume scheme. It is after 10+ years that I have a fully automated methods that just backup the structure I use in every Linux system so that it also can be 'played back' to a (sparse) image file or just raw device. I don't do any resizing, that is not essential to backup; I just re-create that same partition table (also backed up) so I have the same machine after a failed SD-card or HDD with too many bad sectors or just a clone template for a extra new SBC. I use a tool called snapper to create snapshots, both automatic and ad-hoc. It is also integrated in apt and zypper. So before the upgrade to pihole v6, a (read-only) snapshot is created. Also I was bothered by buggy v6, so I just take a read-write snapshot of the last know good/running read-only snapshot and set that that to default, then reboot, or even sync and power cycle. Of course that snapshot (UUID) is also as a differential created tree/folder on my NAS (in case the SD-card or so would fail). Long time ago installers created a lot of subvolumes, like for /home /var/log and many more. That indeed gets into big problems. Just use 1 for the root and snapshot that. That works fine for a workstation like machine with no real data stored locally (all is on NAS). Note that since kernel 6.1, btrfs send can send compressed data, so as it is stored on storage device. That saves time (and money) on mobile links for example. You can compress and decompress via rsync or ssh or vpn, but it costs extra battery energy. Also how long does "make atomic snapshots" take on a 4TB HDD of a subvolume of 2TB you think?

Hello @Aknot, better late than never? This is likely because USB OTG support is on out of the box now. You used to have to add an overlay to get it to work. You will need to modify the the overylays to change this.

I found my NanoPi Neo Air's could not list or connect to some wifi networks. Some investigating found this was because channel 12/13 are disabled by default. Nothing in runtime had any effect on the output of iw reg get as it should have. Patching in some firmware fixes worked for me. wget http://ftp.be.debian.org/pub/software/network/wireless-regdb/wireless-regdb-2025.02.20.tar.xz tar xf wireless-regdb-2025.02.20.tar.xz sudo cp wireless-regdb-2025.02.20/regulatory.db /lib/firmware/ sudo cp wireless-regdb-2025.02.20/regulatory.db.p7s /lib/firmware/ sudo iw reg set AU #Australia I can now connect to wifi channel 13. Now for my question: I read in this old thread that armbian-firmware-full is required for wifi. would that mean that the full firmware package is desirable for the Nanopi Neo Air? When running apt-get install armbian-firmware-full it states it will consume an additional 1gb of disk space. Hardly desirable for a little device. VERSION v25.5.1 for NanoPi Air running Armbian Linux 6.12.30-current-sunxi

I disassembled my tv box - there are 4 screws under the 4 rubbery feet. Removed the motherboard and I drilled some holes of 1/4 inch (7 mm) diameter through the bottom plastic piece. Then I placed a USB fan underneath the tv box and wow the temperature really goes down and stays down around 45 C to 60 C depending on work load. The fans are 80mm and 120mm in size. I chose 120mm to be sure.

That's a very good idea, especially if my online accounts that have my photos would ever become problematic for any reason. I have armbian on a tv box with SMB (samba) and with a USB 3.0 hard drive. The tv box is connected by gigabit ethernet to my home network. So I am going to try these apps - PhotoSync, FolderSync, CX File Explorer - on my android phone to backup my personal photos and videos and determine which is easiest and fastest. Which app on your phone/tablet have you chosen to use to backup your photos/videos?
