Step 2. Specify Backup Policy Name and Description
At the Policy Info step of the wizard, use the Name and Description fields to enter a name for the new backup policy and to provide a description for future reference. The maximum length of the name is 127 characters; the following characters are not supported: \ / " ' [ ] : | < > + = ; , ? * @ & _ .
When Veeam Backup for GCP runs a backup policy, it adds the first 20 characters of the policy name to the names of snapshots created by the policy.
