Re: [rdiff-backup-users] Backing up from Linux to Windows?

[Austin Roberts]

I've done some rough hacks to the 1.2.5 source to try and test the \\?\C:\etc.

I've found that 

>>> os.mkdir(u"\\\\?\\c:\\backups\\dir"

Works fine, but

>>> os.mkdir(u"\\\\?\\c:\\backups/dir"

does not.

Unfortunately, the latter is what is produced when rdiff-backup adds a directory to the current path. Using os.path.join(existing_path, new_dir) will add the separator specific to the host operating system. I'm familiarizing myself with the rdiff-backup codebase, so I'm hoping it won't be too long before I can figure out where to make the needed changes.

Perhaps someone reading this could point me in the right direction?

so, \\?\C:\Temp\ works, but \\?\C:\Temp fails. WTF?

And a followup, almost as a note, if we change to unicode, then it works...

Gah.
