    Thanks for all the tips and answers, I will consider the mentioned
    alternatives.

    Yet I have one more question...

    Can even a full bakcup done safely on a live filesystem by "dump -L"?

    As dump(8) says when explaining the -L flag:

     To obtain a consistent dump image, dump takes a snapshot of the file
     system in the .snap directory in the root of the file system being
     dumped and then does a dump of the snapshot.

    I don't see how the temporary snapshot can improve the
    reliability/consistency/correctness of the dump. Could someone explain
    this?
