A systems engineer needs to size a new project that requires offsite backup using Veeam.

To size a new project that requires offsite backup using Veeam with an RPO of 24 hours and the ability to restore from the past 7 days of backups, while considering the data change rate of 1%, the SE should configure the Nutanix Sizer with the following parameters:

Backup Frequency: Since the required RPO is 24 hours, a daily backup schedule should be set.

Retention Policy: The retention policy should be set to retain daily backups for 7 days. This means that each backup is kept for a week before it is overwritten.

Data Change Rate: The data change rate is 1%. This information is crucial for sizing the backup storage. A 1% daily change rate indicates that each daily backup will be approximately 1% of the total data size.

Backup Target: Veeam should be configured to send backups to an offsite location. This can be an external storage repository or a cloud target.

Storage Calculation: Calculate the total backup storage requirement. If the total data size is D, then the daily backup size will be 0.01D. Over 7 days, the storage requirement will be approximately 0.07D.

The SE should enter these details into the Nutanix Sizer to ensure the configuration aligns with the prospect's requirements.
