bad file names

The windows filesystems, NTFS in particular, do not support filenames with the following characters:
\/:*?"|

Unfortuantely some unix programs DO use these characters. In my case, it is vpopmail which means the rsync fails with a rename error because of files like ".1109341722.21837.computername,S=2944:2,S.006340". If you try and create this file on windows it won't work because of the colon (:).

It seems like this problem could be solved by escaping the problem characters. of course, is the a cygwin problem or a cwrsync problem?

Re: bad file names

Hi,
Rsync v2.5.1pre1 is recently released. One of the improvements is about handling filenames with unprintable characters :
---------------
Non-printable chars in filenames are now output using backslash-escaped characters rather than '?'s. Any non-printable character is output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
is now output as "\\". Rsync also uses your locale setting, which can make it treat fewer high-bit characters as non-printable.
---------------

I am not sure about it will help to solve your problem, since it is about non-printable characters. I will build up a new cwrsync release when the new version is officially released.

Since cygwin is a linux emulation layer on windows, it should handle this naming problem.

Re: bad file names

Any information about this problem?I'm trying to rsync Maildir files to windows, but because the files contain the following sequence ":2," they are not valid under windows!

Re: bad file names

I have the same issue as Carl. I'm trying to back up my Qmail environment to a Windows server using the current version of cwRsync, and it's unable to handle any files with the unsupported characters. Unfortunately, there are quite a few files that meet that criteria.
Any time estimate on an updated version of cwRsync that will resolve this issue?

In the meantime, are there *any* other workarounds possible at this time?

Thank you!

Re: bad file names

AFAIK, no solution exists yet. If possible, you can make archives containing files with unacceptable chars in their names.

Re: bad file names

Is there a solution for this yet? I'm having exactly the same problem (rsync from linux Maildir to cwRsync service on Windows, colons in file names cause problems). I'm not keen on the idea of making archives, because it complicates my backup process significantly, and since most of the email messages files won't be changing I'd really like to allow rsync to handle the smarts of what to copy and what not to.
Thanks!

Re: bad file names

Ok, I've just noticed that cwRsync 2.1.1 might contain a fix!

Re: bad file names

It certainly appears that 2.1.1 contains the transliteration patch which will allow conversion of : to ! (or whatever), however...  How do I pass a command line option to the server, or is it also implemented as an rsyncd.conf option?  I've looked at the patch itself, and it appears that it's only available on the command line, and I haven't yet found a way to pass command line arguments to the cwRsync windows service.

Thanks,

Randy

Re: bad file names

AFAIK, there is no need for additional instructions as the patch is made to work at the receiver side automatically.

Re: bad file names

Sorry if I wasn't clear. The sending end is a linux box running unpatched rsync, the receiving end is a windows box running patched cwRsync as a service.  The linux box is sending Maildir filenames containing colons to the windows box.  I'd like to tell the windows service to do the transliteration as it receives the files.

Re: bad file names

I took a test and it seems that transliteration is not available as a daemon option. It can only be used as a client option at the sender side.
