how does fsarchiver handle btrfs subvolumes

Post by bj0 » Mon Aug 08, 2011 1:04 am

I want to convert my rootfs from btrfs to ext4, and was thinking I could use fsarchiver for it. Unfortunately I cannot find any info about how fsarchiver handles subvolumes. When you install an ubuntu machine with btrfs, it creates a @ subvolume for / and a @home subvolume for /home.

Since you specify devices on the commandline instead of mount points, if you do fsarchiver on this partition, what gets backed up? How do you restore it properly?

Anyone tried this yet?
