Digging into online backups now after getting tired of buying disk drives... hehe.
After investigating Crashplan, really don't like the fact that they only store your data in one location:
Your backup is stored in one of our data centers located throughout the US and around the world.
I guess for $6 per month, you can't expect the whole world...
Also found this lengthy/popular blog article (albeit from 2011) regarding about 20 users losing all their data:
Thank you for your patience as we looked into this issue. Unfortunately, I have some bad news regarding your maintenance job. Your backup archive had corrupted data, and the archive could not be properly repaired by archive maintenance in this situation. This is a very rare situation.
Later part of the post, the CEO admitted that there were human errors that was the root cause and that they have put a plan in place to prevent it from happening again:
Human error was a blind spot for Crashplan’s system, and there was no process in place to prevent it.
As of now, there’s a new process to prevent this type of human error from happening again.
But it made me think... with the way that they compress/encrypt into a "proprietary" file, I'm really curious what they have done since 2011 to ensure that they can still, in some way or another, retrieve the original files even if data became corrupt.
