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 se-fstab-contain-so-many-btrfs-subvol-entries
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?
Having a low-level copy with dd should not be a problem. On the other hand, rsync'ing the content from a btrfs volume including all subvolumes to another volume regardless of the filesystem will copy the content and should work, without subvolumes, of course. IMHO the openSUSE default of btrfs is a very good choice for a desktop system, ext4 is no better in general, that's why btrfs *is* the default choice :-) -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
