I had only one strange thing happening in ~3 years of using Crashplan. I'm using it for cloud backups but also for "friend" backups - with all the systems backing up to a NAS with Crashplan installed. A month ago my parents had a problem with some files in one folder (bad sectors on the HDD), and I had to recover them from the NAS (their system backs up on the NAS). Using Crashplan on their system, I could only restore about 30% of the files - the others were not listed at all. Recovering the full folder using their Crashplan resulted in ~1.5GB of files. Doing the same on my NAS, I could see all the files and I could successfully recover >4GB of files (all of them). Somehow their Crashplan could not see all the files it backed up, but the target Crashplan did. No idea if this is expected (their account is a free one, where you cannot change many of the retention and backup settings) or it's a bug, but this made me check the cloud backup also and compare the files on the disk with the recovered ones. No problems so far, but I only managed 1TB (of 2.5TB backed up).
