Like any backup solution, you have two things to consider:
- the software/management component
- the storage component
Luckily, EBS snapshots are incremental, so you only pay for the data changes in each snapshot (after the first full snapshot).
You can estimate the cost of storing the snapshots and then add to that the cost of our service. Here’s some info on AWS EBS pricing. And, if you need help with this, contact us!
