Do you mean rebuild them with their contents intact? BTRFS RESTORE sounds like it should be able to, but I've not used it.

Step one is to get your NAS into read-only mode pronto so that nothing gets overwritten.

Then, you can start investigating here: https://superuser.com/questions/415132/how-to-undelete-files-on-btrfs-partition

  Of course, once you are ready to start, it'll have to be out of read-only mode to do the actual recovery.

    Cant really find anything that works just yet, have about 4 TB files in those deleted shares, is it not possible to just backup every deleted files to another readynas and then sort them form there?
    
    SSH is not my strong souit, only messed with it to get the "stuck" 2tb snapshots removed from my 316.
    
    Spend the whole day reading how to backup without getting any smarter, btrfs restore, sounds good, but what command to restore entire shares/folders and not just single files?
