Problem with sync

I am trying to set up an auto synchronize from a FreeBSD server on the Net to my windows box at home. The direction is "local" such that the local dir becomes a mirror of whats online. I see the problem whether I'm doing this via automated scripts or manually attempting it.

It works great for everything excep maildir folders. At 1st I thought the the windows box was showing timestamps with second precesion whereas the BSD box was just showing minute precision, but that does not now appear to be the case. I tried the sync using file size instead of modification time.

My latest theory is that the mail messages in maildir have a ":" in them on the BSD side, but have "%3A" on the Windows side. So these files always show up as different, and are deleted from the windows box and then downloaded again from the BSD box.

Does this sound plausible, and is there a fix?

thanks,
Sean

p.s. I tried deselecting "replace invalid characters with \" but that just made the windows file name not match from the ":" on...

p.p.s. I'm using 3.7.6... I searched through the forums and found one reference to this, stating that after version 3.2, invalid characters could be substituted. But I'm not so sure it's working. I see no other differences in the file names other than the time stamp showing seconds on windows and minutes on unix (but that seems to be ok on all other files!) and the colon issue... I definitely see the %3A on the files once they are downloaded to the windows server, but then those same files are always deleted and re-downloaded when I synch.

There's no fix. WinSCP currently cannot handle such files correctly for synchronisation.

I do not understand this one.

Is there a planned fix for this? :-)

If not, that's fine. I have it synching everything except maildir now, and I can just gzip those dirs and sync those files, perhaps...

If you tell winscp to not do the replacement of invalid characeters, it just stops the file name at the 1st invalid character.

Can you tell exact name (including path) for which this occur?

For a maildir name such as:

1127243058.60634_1.east.2sparrows.org:2,ST

It is copied from unix to windows via winscp as:

1127243058.60634_1.east.2sparrows.org

If you have "do not replace invalid characters" checked in the synchronize settings. If you have it set to replace, the file is xfered as:

1127243058.60634_1.east.2sparrows.org%3A2,ST

It does not do this for me. Instead error massage is shown stating that such file cannot be created. Can you post the script file that you use. Also do you use SFTP or SCP?

I'm using SCP, though this appears to happen with both SFTP and SCP.

Here's the file:

option batch on
open xxx@yyy.com
option exclude "maildir; *mrtg*; *spamass*"
option synchdelete on
synchronize local d:\2sparrows-backup /home
close
exit

It's in the saved profile for xxx@yyy.com where I have it set to not replace special chars (or to replace them).

BTW, I have this working by zipping up maildir, where the ":" shows up in the file names, so it's not a huge deal. It does mean that the zipped file get's synch'd every night.

It seems that at least WinXP (Win2K seems not) does not refuse creation of file with single comma in the middle. Instead it ignores filename part before (and including) the comma. If you have filename with 2 commas or other dissalowed character, error occurs.

any update on fixing the ":" problem on windows?

Any updates on this matter? I still do have the problem that ":" is renamed to "%3A" on windows and thus the synchronize option is not working.

This is not solved yet.
