The problem this fixes is most evident when trying to back up an
entire drive e.g. C:\, but the same problem occurs whenever there is a
trailing slash in the path. The issue is that rdiff-backup has support
for using \ as a way of escaping characters in the path specifier.
This is all fine and common on unix, but on Windows, the \ is
obviously used as a path separator. (There really is no way of
escaping characters like this on the Windows command line. It is
expected that you simple quote everything.) This patch simply disables
escaping if the path separator is a \.
This does remove some functionality: if you are backing up from
Windows to linux, you could have escaped the remote side of the
connection, and with this patch you can't. However, you can still
quote the remote path, and I believe that it's more important to allow
trailing slashes, especially with drive specifications, than
supporting escaping for the remote path.
(This problem was first reported here:
http://lists.gnu.org/archive/html/rdiff-backup-users/2008-08/msg00051.html.)
The patch is helpful I am sure, but a fairly simple workaround for the \
issue on Windows XP or higher is, if running rdiff-backup from a command
script (.cmd or .bat), set a variable to the the path(s) and then use
the variable character replacement capability (do SET /? for info) e.g:
C:\>echo %USERPROFILE%
C:\Documents and Settings\Dominic
C:\>echo %USERPROFILE:\=/%
C:/Documents and Settings/Dominic
By processing all paths in this way in a command script as or before
they are passed to the rdiff-backup command line the problem should
disappear I think. But each full path must be allocated to a variable
for this to work (I cheated above by using a built-in system variable).
(As it so happens in this example there is no trailing forward slash but
you get the idea.)
