Backup & Restore

[StephenM]

What's the best method of backing up my /mnt/md0 (BTRFS) to /mnt/md1 (EXT4) so that I can remove BTRFS and reformat to EXT4?

Hey, this is an invisible directory. As far as I know, TOS does not have a backup copy tool that can handle it.
I think you'd be better off logging into an SSH/Telnet terminal to copy them like this
mkdir /mnt/md1/public/backup_volume_btrfs
cp -r /mnt/md0/* /mnt/md1/public/backup_volume_btrfs/

Where my thinking was going as well.
