I have the root (subvolid=0) mounted in /mnt/btrfs and take there the snapshots, so they are not nested: # btrfs sub list /mnt/btrfs ID 284 gen 15086 top level 5 path root ID 1032 gen 12751 top level 5 path root@2014-01-14_23:45:01 ID 1033 gen 12777 top level 5 path root@2014-01-15_07:45:01 ID 1034 gen 12794 top level 5 path root@2014-01-15_08:00:01 ID 1035 gen 12811 top level 5 path root@2014-01-15_08:15:01 ID 1036 gen 12829 top level 5 path root@2014-01-15_08:30:01 ID 1037 gen 12844 top level 5 path root@2014-01-15_08:45:01 ID 1038 gen 12863 top level 5 path root@2014-01-15_09:00:01 ID 1039 gen 12880 top level 5 path root@2014-01-15_09:15:01 Also, to send a subvolume, it must be read-only: # btrfs sub snapshot -r / /mnt/btrfs/my-ro-root # btrfs send /mnt/btrfs/my-ro-root You can later make a read-write snapshot of a read-only one to work with it. -- Juan Orti GPG Key: DEEBD08B - http://jorti.fedorapeople.org/pubkey.asc Blog: https://apuntesderoot.wordpress.com/ -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
