No. We consider a file deletion as "the final version of the file you wish to retain". In that case you can get the deleted version for 30 days, then it is gone forever.
I'm sorry but this is a complete no-go. As much as I like Backblaze's attitude and pricing plans, this is unacceptable for a backup service. It's way too easy for files to be accidentally, unknowingly deleted, and for this to not be noticed for months or years. Any backup system that deletes missing files is not a backup but a mirror.
