Backup storage calculators and tools

Start with the cost calculator if you are choosing a vendor. Use the restore tools when the question is what getting the data back costs and how long it takes, and the capacity planner when you need to know how much your retention policy will store.

• Backup storage cost calculator Every vendor priced on your workload, for a normal month and for the month you restore everything.
• Cheapest object storage The lowest complete bills for 1, 10 and 50 TB backups, and what a restore deadline changes.
• Amazon S3 cost calculator Every S3 storage class priced on your data, requests and restores, from Standard to Glacier Deep Archive.
• Restore cost calculator A restore adds retrieval, restore requests, a temporary readable copy and download charges to the month; price yours line by line for any vendor.
• Restore time calculator A restore takes the vendor's preparation time plus the download at your bandwidth; at 100 Mbps, 1 TB takes about 22 hours before any archive wait.
• Backup storage capacity calculator Turn your data size, daily change and retention into the capacity you will actually store and pay for, with full, incremental and monthly copies.
• Photographer backup cost calculator Turn shoots, file counts and how long you keep them into storage and restore bills for a photo library.
• Glacier Deep Archive cost calculator, restore included What S3 Glacier Deep Archive, Flexible Retrieval and Instant Retrieval cost to keep and to read back, with the retrieval wait and the minimum days.
• Object storage migration cost What it costs to move backups out of each vendor: reading every object, downloading it, and any early-deletion charge for leaving before the minimum.
• Object size economics Small objects cost more than their bytes: minimum billable object sizes, per-object metadata and per-request restores, and how to price them for a backup.
• S3 or EC2 for an application What files, a server and its disk cost for an app, and which jobs belong in object storage.
• Object storage pricing history Every change we have recorded in object storage prices, with the date it was seen and what it did to the bill.
• Price data, CSV and API Every price we use with its vendor page and check date, as a table, a CSV file and a JSON API.

Every calculator uses the same prices, checked on the vendor's own page, and the same bill: storage, uploads, requests, retrieval, a temporary restored copy and downloads. Nothing you type is stored or sent anywhere.
