In my last post I compared several online backup services and decided that Crashplan was my personal winner when looking at the features and the price. In the following weeks a couple of people started to complain about the slow transfer rates to their backup servers. I also tested the upload speeds from several networks in germany on internet connections with up to 100 MBit in both directions and I could not get any transfer rate above 3 MBit/s.
I also contacted the support which confirmed that Crashplan is not limiting the bandwidth at all. Inside the Crashplan application settings there are a few options which potentially limit the transfer rate but changing those did not improve the situation for me. I’d be interested to know if US customers get better transfer rates.
Anyway, it is quite unusable like this and so I finally gave up on Crashplan for now. Instead I am now evaluating Arq. Since it uses Amazon S3 storage, you can choose the region in which the datacenter is in and that seems to make a huge difference. I was able to upload my backups with up to 4 MByte/s ( 32 Mbit/s ) on a 100 MBit network which is still not wire speed but much better than the transfer rates of Crashplan. The graphical user interface of Arq is also surprisingly simple and pleasant to use. But this is just a small update. More after I have used Arq for some time.
Arq 2 was just released: http://www.haystacksoftware.com/blog/2011/08/arq-2-is-out/
