A.
mount LABEL=Btrfs -o subvol=DocumentsSV_Tuesday_Backup /restored_backup
B.
mount LABEL=Btrfs -o subvol=DocumentsSV /restored_backup
C.
mount LABEL=Btrfs -o subvolid=140 /restored_backup
D.
mount /btrfs/DocumentsSV_Tuesday_Backup/restored_backup
E.
mount LABEL=Btrfs -o subvolid=270 /restored_backup
F.
btrfs subvolume set-default 270 /btrfs; mount LABEL=Btrfs /restored_backup
maybe A,D,E
A E F
Mounting subvolumes requires the specification of the subvolid (name or number). An unspecified subvolid assumes the default (usually 0).
