Package: rdiff-backup
Version: 1.1.5-4
Severity: important

It seems to me that rdiff-backup is innovative and
useful.

I used it to back up a remote computer onto a
local one, and eventually the remote computer's
hard drive failed. 

When I checked the backup copy, I was surprised to
learn that rdiff-backup had silently changed uids
and gids. Furthermore, unless it's smart enough to
check that the new uids or gids aren't already in
use, it seems to me that the data corruption is
irreversible.

One might say that using

    --preserve-numerical-ids

avoids the problem, but that's little consolation
to someone who reasonably assumed their data
wouldn't be altered, and who's faced with the
somber reality of having no backup.

I suggest that rdiff-backup *not* alter data by
default. That way, nothing would be irreversibly
lost.

Thanks,
Kingsley
