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.
UPDATE
Arq 2 was just released: http://www.haystacksoftware.com/blog/2011/08/arq-2-is-out/
arq rulez, there is a beta out now, should be released soon:

What’s changing with Arq 2.0?
I no longer use Arq because other services are more affordable if you want to backup multiple Macs. Another major problem with Arq were file selection and backup status. It was never clear which files were actually part of the backup and restoring versions was rather messy.
Arq 2.0 might change that, although still being limited by the costs of S3.
Hi Martin,
With Arq 2 you can select/unselect individual files/folder within a folder that Arq is backing up. You can see a list of all the files it’s backing up; sort the list by file size to see what the bulk of the upload is. Also, Arq 2 does “binary diff” — it only backs up the changed parts of large files; it also compresses everything.

I am using crashplan for a while now, and it works perfect for me. The (potential!?) lack of upload speed is not an issue for me, because my internet connection is quiet slow
The initial upload of 105 GBs took about 15 days, my incrementals are not to big, i have scheduled just one backup during night-time in order not to limit my bandwith the day over.
Compared to others, crashplan is attractive because of their pricing…
Thanks for the review.
I decided to stick with crashplan. At first my connection is so slow – it really doesn’t matter how far away the servers are and the second point is that i’m archiving video material which is eating up all my disk space… .so… unlimited sounds good to me
