Painful restore process. Horrendous support. As a small business we paid Crashplan hundreds and hundreds of pounds over years to keep our data safe, knowing that one day we'd have to restore a backup. After a hard drive failed, that day came, and with it another shock; the restore process. It took days upon days to recover some of the files over ridiculously slow transfer rates. Software crashed, or failed to log in, transfers failed part way through, and direct downloads (limited to 250MB) via the web dashboard failed regularly. Terrible support service via email who basically didn't want to know. Avoid this company at all costs, there's far better solutions out there.

Like others have commented Like others have commented, they keep changing their terms & conditions and now for the first time ever I need to get my files back after replacing a device. Got about 10% of my files back. Software functionality pathetic. Now forced to download the files manually through their rubbish web interface. There is one reason and one reason alone to use a Cloud backup and that is data security. I am afraid you will NOT get that from this solution. DO NOT USE this software.

Probably the best online backup solution Probably the best online backup solution I have ever tried. And I have tried quite a few. CrashPlan is extremely cheap compared to the amount of backup storage (unlimited), meaning storing many versions of files for no extra charge. Furthermore, there is no retrieval waiting time (like Amazon Glacier). Anyone complaining about the data transfer speed just doesn't know that it helps a lot to disable backup compression. My transfer speed is excellent.

Unlimited is not unlimited Unlimited is not unlimited. Software is unable to handle large amounts of data. Customer service advises I delete all my data to resolve issues. I've been paying for years, and now they're kicking me off without letting me download any of my data.

Total monsters Total monsters. They had an excellent product then they burned their customers and destroyed their backups by giving them no way to recover their data. They certainly warned us, but they went the extra step of destroying the installed clients on people's machines and making it impossible to recover later. Their support says there is no way they can help the punished users. One person made an app that does something they say is impossible. look at github OurDataNotYours/PlanC
