Hi Shelly,
Hope you are doing well.
To approximate the cost reduction after deleting a virtual machine (VM) for which you are taking backups, you need to consider the following factors:
- Calculate the amount of storage space occupied by the VM's backups. If you're using a cloud-based backup service, determine the monthly cost of storing this amount of data.
- Determine the backup retention policy for the VM. How long do you retain backups for this VM? This will affect the overall cost of backup storage.
- Consider how often backups are taken for this VM. The frequency of backups affects the total storage consumed and, consequently, the cost.
- Review the pricing structure of the backup service provider. Are there any fixed costs, variable costs based on storage usage, or additional charges for backup operations?
- Some backup services may charge for compute resources used during backup operations, such as CPU cycles and network bandwidth. Consider whether these costs apply to your backup solution.
Once you have gathered this information, you can estimate the cost reduction after deleting the VM by calculating the difference in backup storage costs.
Best Regards
