- .5 cents/GB/mo
- 1GB/day free egress, 1 cent/GB after
- generous free API call allowances, cheap after that
- $0.0059 cents/GB/mo (18% higher)
- all storage billed for at least 90 days
- minimum of $5.99 per month
- this doesn't include delete penalties
- all objects billed for at least 4K
- free egress as long as "reasonable"
- free API requests
- overwriting a file is a delete, ie, delete penalties
With HashBackup (I'm author), an incremental database backup is uploaded after every user backup, and older database incrementals get deleted. Running simulations with S3 IA (30-day delete penalties), the charges were 19 cents/mo vs 7 cents/mo for regular S3, even though S3 is priced much higher per GB. So for backups to S3, HashBackup stores the db incrementals in the regular S3 storage class even if the backup data is in IA.
For Wasabi, there is no storage class that doesn't have delete penalties, and theirs are for 90 days instead of 30.
Either way, Wasabi is about simplicity and doesn't have any concept of storage classes. It's true that there's a 90-day min storage fee involved but that's only an issue if you're deleting constantly.
