Uses chroot to pretend for restic that the latest snapshot is actually the whole filesystem.
Restic can then create its backup snapshot in peace while the live file system can change without any conflicts.
All orchestrated by systemd timer and service unit.

Sounds pretty neat! Could perhaps learn something for my own backup solution.

A really nice overview and somewhat in-depth explanation of setting up a nice backup system with restic and systemd. Written exclusively for btrfs I am not sure why, since most of the instructions should work with most any underlying filesystem.

For the error '202803 – Hibernation does not work with BTRFS and swapfile on 5.0 kernel. Cannot find swap device.'

• btrfs physical_location is different from normal filefrag physical address.
• There is a tool to get the physical address of the swapfile in the comments

The full process is described here: https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate#Hibernation_into_swap_file_on_Btrfs

Remember to divide by pagesize!

Another explanation of installing arch with BTRFS and encryption - this time with encrypted boot partition and grub bootloader.
