I can only suggest that after snapshooting the "/", you snapshot their subvolumes, placing these under the root snapshoot itself: Supposing to have the following four subvolumes /root/ /root/etc /root/usr /root/var When you need to snapshot, you should: # btrfs subvolume snapshot /root /backup-root-20141120 # btrfs subvolume snapshot /root/etc /backup-root-20141120/etc # btrfs subvolume snapshot /root/usr /backup-root-20141120/usr # btrfs subvolume snapshot /root/var /backup-root-20141120/var So in order to remount an "old" filesystem, you need to make only 1 mount. > regards Jakob > > -- To unsubscribe from this list: send the line "unsubscribe > linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- gpg @keyserver.linux.it: Goffredo Baroncelli <kreijackATinwind.it> Key fingerprint BBF5 1610 0B64 DAC6 5F7D 17B2 0EDA 9B37 8B82 E0B5 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
