QOS with online backup service

    I'm starting a free month trial with carbonite.com, which is an online backup service. I can set the service to backup certain files, and I can decide to backup at a certain time, or, in the alternative, it will backup when it detects that my computer is not otherwise in use.

    Any suggestions on setting QOS with something like this? I read a post elsewhere that says Carbonite uses ports 25 (smtp), 53 (dns), 80 (http), and 443 (ssl). I have Vonage (with the port on my Tomato router currently giving the Vonage device highest priority), and would like to give Vonage and web traffic priority over Carbonite. Since Carbonite uses port 80, I'm not sure if my current QOS settings will work.

    I use Mozy, which is similar. Basically, all transfers are done on TCP port 443 over a secure connection. What I have is a rule for my VOIP device as HIGHEST, a rule for WWW which includes TCP ports 80 and 443 for 0-512kb on HIGH, then another rule for TCP ports 80 and 443 on LOW for 512kb+. If you're curious how to make a rule 512kb+, just full in the first box for KB Transferred in the QOS rule and it will make it that value and above.

    What this will do is drop the priority of your backup to LOW because it will >512 kb. Any phone calls will always take priority.

    Hope this helps

    Thanks, I'll see how this works. I don't know if it was a default setting or something I did a ways back and just don't remember, but I have 512+ set at low (plust VOICP at highest and 0-512kb for WWW at HIGH), so I'll see how things work.

    Or you could work out what IP addresses the Carbonite service is using, and create a rule based on that. This way you can keep your normal rules for Port 80 and 443 traffic.
