How Veeam Backup for Microsoft Azure Estimates SLA Compliance

To estimate SLA compliance for an SLA-based backup policy, Veeam Backup for Microsoft Azure performs the following steps:

1. Calculates the SLA compliance ratio individually for each Azure VM added to the backup scope. The SLA compliance ratio equals a percentage of restore points successfully created for the VM out of the total number of restore points expected to be produced by the SLA-based backup policy for this VM.

When calculating the SLA compliance ratio for daily, weekly and monthly restore points, Veeam Backup for Microsoft Azure takes into account snapshot and backup settings configured while creating the SLA template that is assigned to the SLA-based backup policy.

2. Uses the ratios calculated at step 1 to determine the average SLA compliance ratio for the policy.
3. Compares the target SLA value configured for the policy to the average SLA compliance ratio calculated at step 2. If the target SLA value equals or is less than the average SLA compliance ratio, Veeam Backup for Microsoft Azure marks this policy as meeting SLA standards.
