I started using Crashplan for my backup needs back when Mozy switched away from doing an unlimited backup. Initially I was very happy with their service.
However, since at least June of 2012 when I first noticed it, Crashplan has had horribly slow upload speeds. Many people are getting much less then 1mb uploads even though their internet connection supports speeds many times faster then that.
For anyone who frequently adds files to their backup set, this would make crashplan almost useless since you would never have a complete backup. You would always have files pending to be uploaded.
I myself could probably live with these speeds since I don't often add files to my backup. What I can not live with though is a company that lies. And crashplan lies. Their support has NOT ONCE responded to the thread I started here: https://crashplan.zendesk.com/entries/21660011 (they require you to register to view threads, probably to hide complaints from showing up in search engines - i'll post a complete copy at the end of this post).
That thread is almost 6 months old and has NEVER received a response from someone in support. It did however receive a response within a day when I finally got fed up and accused them of being incompetent or liars. Then a Mike Evangelist (listed as Chief Marketing officer according to his linkedin profile) suddenly stepped in and deleted my post accusing me of 'name calling'. I'm not sure what other conclusion you can come to when you have a problem that's ongoing for months and the only response you get from CP support, if they respond at all, is to tell you the internet is shared resource. Basically their excuse is that the internet is slow, not them. Apparently the internet has been slow, ONLY for crashplan customers, night or day, for months.
His idea of customer support was to offer me a refund. That's a pretty shoddy business model - no actual response to the problem itself, just someone who gets upset when you use harsh words about the lack of support and communication and then tells you to leave.
The only conclusion I can draw is that crashplan is either incompetent and doesn't know how to fix the problem or is otherwise incapable of doing so, or they are lying to me. I think it's both. I suspect they signed up too many users too fast and don't have the resources to support them all and are just hoping people wont notice.
As I said earlier, I could probably live with the slower upload speeds. But I will not do business with a company that treats their customers like this. They lie to their customers pretending there is no problem or pretending the problem is with you and not with them. They don't respond to complaints in their forum for MONTHS and then the only official response they finally give is to delete a post that calls them out for what they are - liars.
I don't know about you, but I would not do business with a company that is dishonest with you and treats their customers like idiots. Would you trust all your personal data with them? What's going to happen if their servers ever get hacked, do you think they'll actually let you know? Can you be sure you're data is really encrypted and safe on their server? And what happens if some day you need to download your data, how can you be sure you'll be able to get it? Or that it wont take months or years to download because of their poor service?
I apologize if this sounds like a rant, but I am angry. I think anyone would be angry if they are lied to for months on end. Because of this I've canceled my subscription to crashplan. Oh, and they are actually planning on raising their rates at the start of 2013. I'm going to use amazon glacier with cloudberry. Shockingly, the shared resource that is the internet seems to have no problem maxing out my upload speed when uploading to amazon. And it'll cost me less then what crashplan charges.
Edit: I've been using cloudberry in conjunction with amazon glacier for several weeks now without a single slow down. And it's only costing me $2/mo. To be fair, it looks as though the issue with crashplan has been resolved, at least the technical issue has. The customer service/honesty issue though has not. Crashplan only once admitted to there being any problem and it was a rather vague message along the lines of 'some' customers report problems and 'they are looking into it'. No explanation as to what the problem was. No explanation as to what they did to fix it. No sort of apology. I still don't trust them.
Edit 2: It loosk like CP might still be lying to their customers. Someone who just signed up with CP starts off getting 6mbps uploads but then quickly drops down to 250-300kbps. When they contacted CP support, this is what they were told:
I looked over your backup logs from the past few days and it looks like everything is going exceptionally well. 200-300 KBps sustained transfer rates are normal for most people and are common when the CrashPlan Client is backing up media files or other large chunks of data (applications come to mind). Those types of data don't compress well and therefore have to be sent in their entirety versus smaller chunks that have already been efficiently indexed by the CrashPlan Client.
That's the first time I've heard that not being able to compress file means it'll download MUCH slower then your maximum internet connection. The support rep went on to say turning off data de-duplication might speed up the upload. Which I assume is also either a lie or an indication their system is poorly made if data de-duplication means a 20x reduction in upload speeds.
Edit 3: For anyone still using crashplan and having problems, you might want to take a look at this blog post. He greatly sped up his upload speeds by disabling the deduplication function in crashplan's client.
