I was looking to make an exact copy of a tumbleweed root btrfs filesystem on removable media. One aspect that makes this more fiddly is the number of subvolumes that are part of the root filesystem, including /opt and many sub-directories of /var. Is there any technical document describing the reasons behind having so many subvolumes? Someone else was asking the same question at stackexchange (with no real answers) : http://unix.stackexchange.com/questions/285011/why-does-my-tumbleweed-opensu... Is there a recommended way to get a faithful offline bootable backup of a btrfs rootfs? Finally, I'm not determined to use btrfs. I'm moving up from 13.1. I'm evaluating Leap and Tumbleweed. It's a simple desktop, no RAID, one user. Would ext4 be a better choice?
