Budget for keeping it.
And getting it back.
Model your regular storage cost or a month with a large restore. Use current rates and allowances from the provider you are considering.
What is included
Stored GB = live TB × 1,000 × retention multiplier
Storage cost = stored GB × price per GB-month
Egress cost = max(0, downloaded GB − free allowance) × egress price
Total = storage + egress + other costs1 TB means 1,000 GB here. The multiplier is a simple estimate of retained backup data, not the number of snapshots. Deduplication, compression and change rate affect the real amount. Enter the billable retained amount from your software when possible. This model does not apply tiered rates, storage minimums, early-deletion fees or provider-specific egress rules automatically.
Check product fit before price.
A desktop backup subscription and object storage solve different problems. Backblaze documents that its Computer Backup product excludes NAS and network-mounted drives; B2 is its route for supported NAS workflows.
