Ahhh yes, Crashplan, the company that purposefully locked everyone out of their backups when they shut down their personal backup service.

I had a drive fail and I thought I was OK...and then I discovered that my Crashplan backup archives on my own server were unreadable after they shut down Crashplan personal backup services.

I couldn't even install the client, either - they silently updated the client to have a logic time bomb and refuse to install.
