Because I was 98% sure I did restores into a directory without
amrecover erasing files, I tried a test. And indeed, when
being careful, amanda/tar does not existing files/directories.
I came to the conclusion that it is indeed because the
directory "." was added to the extraction list. Adding "." means
restore this directory as it was, overwriting existing files,
and removing newer files.
However, the dangerous thing it seems is that "add *" also adds
files beginning with a dot, and the directory "." itself too.
If I remove dir "." from the extraction list, no files in that
directory were deleted.
Conclusion: maybe "add *" should not add "." by default.
What about dot-files? What about "add .*"?
Proposal: "." should never be added except when mentioned
explicitly.
Adding warnings to amrecover is fine, as long as you don't
create a habit of ignoring it by asking too many times:
C:> del file.txt
Are you sure? y/n
Below is my test. I added my comments with lines beginning
with '##'.
