Error while creating backup set using a content rule that is attached to another backup set on the same server
The following error is encountered when you try to attach the same content rule to multiple backup sets under the same server:
Cannot proceed as this content rule is already part of another backup set on this server.
Phoenix does not allow you to create multiple backup sets with the same content rule for a single server or workload.
To attach the same content rule to the new or existing backup set, duplicate the existing content rule and rename it.
For detailed steps, see Add a content rule.
