Hi there! I'm new on btrfs, and I like it :) But i have a question. I have a existing backup on an external HDD. This was ext4 before i converted it to btrfs. And i installed my debian new on btrfs with some subvolumes. (f.e. home, var, multimedia/Video multimedia/Audio...) On my backup there are no subvolumes. Now i wrote a script to take local snapshots on my laptops HDD an mirror this snapshots with btrfs send/receive to the external HDD. An i don't know, how to do, to make the inital snapshot on the external HDD. I want to use the existing data there, so I don't have to transmit the whole bunch of data to the external drive, which exists there already... What happens, if i make the same structure on the external drive with creating subvolumes and »cp --reflink«, give this subvolumes the correct names, and fire a »btrfs send«? Or is the best (ONLY???) way, to make an initial snapshot on the external drive and delete the old backup there? greetings jakob -- http://xundeenergie.at http://verkehrsloesungen.wordpress.com/ http://cogitationum.wordpress.com/ -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
