Hello, I tried to backup a partition to an ftp server (Authentication + Passive) under Windows XP SP2 (Windows Firewall Enabled). Arconis shows the progress up to 99% and never reachs 100% (like an infinit loop without cpu usage). With tier client, I looked into the ftp server and the archive seems to be ok. If I disable Windows Firewall, the backup works like a charm. So I tried to add exceptions in Windows Firewall for these applications : TrueImage TrueImageService TrueImageMonitor TrueImageNotify But still doesn't work when Windows Firewall is enabled. The only way is to deactive Windows Firewall but I can't do this for security concerns. Any help would be appreciated, Benoit PS : The backup works if I select a different destination location than ftp server.
