CrashPlan (online backup) and bandwidth throttling??

Hi,

I hope some Sonera representatives keep an eye on these forums.

I'm having some really annoying speed issues with my broadband service, which is a standard 24mbps/1mbps ADSL. Basically I am using CrashPlan for the offsite backups of my laptop, and I have noticed that each time the backup is running both download speed and latency become ridiculously slow, i.e. download speed goes down from ~17mbps to 2-3 or even under 1mbps at times, and the latency e.g. with "ping google.fi" (for example) goes instead up from ~20ms to 500ms or even more at times. Of course surfing the Internet or watching news or videos is a challenge in these conditions.

I have tried countless times to switch the online backup on and off and am 100% certain that as soon as the backup is running, speed goes down and latency goes up. As soon as I pause or switch the backup off, speed goes *instantly* up and latency instantly back to normality. The only way I can avoid this is by limiting CrashPlan's upload speed to 3-400kbps, which means it will take *months* to backup my data!!

I have used CrashPlan for years and have never had problems with the service, and anyway this is a backup service that should only affect my *upload* speed when running the backup and doing something else at the same time. It should *not* affect download speeds or latency.

I have no doubt that something is going on here, and would like to know why Sonera is throttling my bandwidth this way. I am using (trying to use) my usual online backup service, I am NOT doing P2P etc.

Any ideas? I recently moved to Finland and am really upset with the service so far, hands down the worst I have experienced. Especially considering that my work is entirely online based, and I basically have to choose between safely backing up my data and normal Internet usage.

    I've just tested the speed with the Sonera tool I've seen others use in other threads.

    With CrashPlan *PAUSED*:

    With CrashPlan *RUNNING*:

    Look at the horrible speed and latency! If I then pause the backup all looks good again almost instantly. Why, oh why is Sonera doing this??

    Are there any other CrashPlan users in these forums?

    Hello Sisupoika

    That sound littlebit strange. Backuping should use just upload line. Only thing what come's in my mind is "overload" of modem or connection when you use whole upload line. Do you use wireless connection between to modem and computer?

    Do have try another modem?

    Hi Arttu,

    thanks for your reply! Really happy to see Sonera staff actually replying to discussions here.

    Well I had some weird (but nice) surprise - I phoned support and was advised to try the modem that Sonera sent me (a "basic" Zyxel) instead of my own modem (a more featured Netgear).

    So I did, and it's really weird, but while the Zyxel syncs at max ~15mbps (the Netgear syncs at ~17mbps), the problem I described seems to have gone. CrashPlan is now running without limiting the upload (my anyway 'tiny' upload - me cries) and latency seems normal, and download speed doesn't seem to be affected.

    At the moment my priority is to be able to backup off site, so I don't care too much if the Zyxel syncs at a little lower speed.

    It's really, really weird that the issue shows up with the Netgear, I checked QoS and whatever else I could think of, and the issue seems even more weird because besides the CrashPlan thing, everything worked wonderfully.

    Anyway, I want to be fair with Sonera this time and apologise since it doesn't look like a 'bandwidth throttling' issue after all. I will investigate more on the Netgear when I have time just out of curiosity, but for now I am pleased if I can use the broadband normally with the peace of mind CrashPlan is doing its thing in background.

    I want to take this opportunity - since you replied - to ask something else related: is there anything I can do to bump up the upload speed? I don't know, some sort of upgrade or something? (my broadband is currently a 24/1).

    I've tried to set the Zyxel to use Annex M but I didn't see any difference really. I've also read somewhere about Sonera 'extra' but I am not sure of what it was. Any suggestion?

    Thanks!

    Nevermind on the upload speed etc - it just occurred to me that someone had already replied to the same question I asked time ago but I didn't have the notification of replies enabled.

    Are there any plans to bring fibre optic to Espoo/Viherlaakso area? :(

    I have Sonera 10/2 ADSL at home and am using Crashplan.com for backups. The upload speed to CrashPlan was too slow (<500K) so I got also Sonera 4G (connected to my iMac w/ USB modem). Speedtest.net gives something like 40/25 speed but Crashplan still remains under 500K so no change Is this purely because of Finland-USA connection or something else?
