It is important to calculate the amount of resources you need to efficiently back up your online service. Many organizations have turned to AWS EBS snapshots as a backup solution, however, without the right knowledge, the cost of snapshots may seem to get out of hand.
EBS snapshots solely copy the blocks of the disk that were written to as of the last snapshot, meaning if part of a disk was left unchanged, it won’t be included in the snapshot. While this approach tends to save on costs, in order to properly estimate the cost of backing up your AWS environment with EBS snapshots, you need to consider three main factors:
- Data size
- Data growth rate
- Backup retention period
Although these factors vary, we’ll help you calculate costs with a broad estimation based on a few use cases. Remember that when costs pile up, losing your data can cost you much more than backup, alone.
