I agree, for things like Google Drive, OneDrive, etc. Usually if the service is a flat rate and/or unlimited, there are gonna be issues around performance, both upload and download. Rather than impose hard data size limits, these services usually make upload and/or download so painful at higher sizes that they become unusable or infeasible. There are many services these days that have minimum retention times, including the cheaper tiers of S3 and GCS. Backblaze doesn't throttle, has no minimum retention times, no minimum object size, and is 0.5 cents/GB/mo for storage and 1 cent/GB/mo for downloads with a 10GB free monthly storage allowance (without registering a CC) and a free 1 GB/day download allowance. Not associated with BB other than through HashBackup (I'm the author). Many of HB's large customers successfully use BackBlaze for their offsite backups. It's rock solid if you strictly follow their API guidelines, esp related to error handling.
