Problem uploading large files with .tif extensions

[Bernard Robinson]

I backup client's data remotely to my server behind a NAT router. I service about 20 clients. The data contains .doc, .bak, and .tif file extensions. I upload from multiple clients at a time. The size of uploads range from 4 GB to 45 GB. Client's data that is 6 GB or smaller seem to transfer ok. Now the clients with data larger than 6 GB seems to always fail or never completely transfer over. So i end up with a way smaller file size after transfer. Whenever i try to open any of the image files that were transferred, i receive this error message stating "The Compressed (zipped) folder is invalid or corrupted". What can i do to prevent this problem from happenening?

I also notice that the uploads take 24-48 hrs to fully complete. Is this normal? Or would that have to do with the speed of my ISP?

On another note, when i check the status of the uploads, i notice that some of the clients that have already finished the file transfer, are still shown in the status pane. No progress shown but the ip address and user's name of the file that was transferred are visible. I would usually just have to "Kick User" to clear it from there. Is this a common problem, and will it have any effect on any existing downloads/uploads?

Which software is used to upload the files?

Please attach logs of such a failing transfer.

I use Cobian 10 to remotely backup the data to my Filezilla Server.

Can't attach log files for they contain client's personal information.

Triage suggestion

No log files could be provided by the user. In addition, Windows Server 2003 is no longer supported by Microsoft (its extended support expired in 2015). Finally, this ticket is seven years old.

I suggest closing this bug report.
