I’ve been using Bitcasa as a cloud backup solution as I work for about 16 months now. Initially they were great, I’d synced about 260gb of photos and work data to them before I left the UK and everything was running smoothly. I felt secure that my laptop backups were working and my data was safe in case of user error or laptop theft.
Then Bitcasa deleted all the data I’d backed up in November 2014 as they were re-architecting their backend.
