Thank you very much for your advice. It worked! I verified that the superblocks 1 and 2 had similar information with btrfs-show-super -i 1 /dev/sdc1 (and -i 2) and then with crossed fingers: btrfs-select-super -s 2 /dev/sdc1 which restored my btrfs filesystem.
Then I runned scrub. For future reference, scrub was "stuck": " # btrfs scrub status partition/ scrub status for c1eb1aaf-665a-4337-9d04-3c3921aa67e0 scrub started at Thu Jul 10 21:30:41 2014, running for 2743 seconds total bytes scrubbed: 193.47GiB with 0 errors " and could not cancel it: " btrfs scrub cancel partition/ ERROR: scrub cancel failed on Downloads/: not running " After deleting /var/lib/btrfs/scrub.status.c1eb1aaf-665a-4337-9d04-3c3921aa67e0 it was completed successfully.
