Thinking about it, there is soom room to make this harder to do by
accident. I just committed this change:
diff --git a/src/s3ql/fsck.py b/src/s3ql/fsck.py

In the later case, waiting for a while should fix the problem,
in the former case you
should try to run fsck on the computer where the file system has
been mounted most
recently.

+ You may also continue and use whatever metadata is available in
the backend.
+ However, in that case YOU MAY LOOSE ALL DATA THAT HAS BEEN
UPLOADED OR MODIFIED
+ SINCE THE LAST SUCCESSFULL METADATA UPLOAD. Moreover, files and
directories that

CONTENT LOST.

Hopefully this will prevent some such accidents in future.
Best,
