urBackup Webinterface error when downloading large files

Hi All,

Have anynone experienced this problem? When trying to download a large file (example 1 GB Pst or greater) the webinterface displays an error Unable to connect, then you have to restart urbackup service to be able to login again.


This is a limitation of the internal web server. You should be able to connect once you finished downloading your file.

If you are on Windows you could fix this by appending


to C:\Program Files\UrBackupServer\args.txt

or by putting a proper webserver like apache in front of UrBackup: http://www.urbackup.org/Administration_Manual.php#x1-80003.2

If you use the backup web access extensively I’d also consider using something that is good at it, like AJAXPlorer. Or make it accessible via WebDAV or samba.
