If you use Google Docs or Drive, make sure you backup your important files. I had a password file (encrypted, of course) in Google Docs; it's not there anymore. Either are 99% of my other files. One got left behind - a recipe file.
I had to piece together a new file from Ark archives on a number of different computers. Took about one hour. So much for cloud storage.
If anybody knows how to get Google Docs back, please let me know.
