Exam E20-891: Backup Recovery Solutions Expert Exam for Technology Architects

What needs to be done to ensure backups continue to run with minimal impact to operations?

An EMC customer has a large Microsoft SharePoint 2010 environment. The environment consists
of three separate distributed farms with several web front-end and content database servers. An
Avamar solution was deployed to protect this environment, backing up the SharePoint data to
Data Domain Boost devices on the back-end. Backup data is replicated by Avamar to a disaster
recovery site in another location.
The web front-end server in one of the farms where the front-end plug-in is installed experienced a
disaster and all data on that server was lost. What needs to be done to ensure backups continue
to run with minimal impact to operations?

why does the Data Domain available capacity remain the same?

A customer has EMC NetWorker integrated with Data Domain. They noticed that they have

incorrectly configured their NetWorker Browse and Retention policies for all currently defined
clients. This issue was discovered when a DPA report was e-mailed showing the amount of
available space on their EMC Data Domain system.
The customer has made the necessary corrections to the Browse and Retention policies. They
have manually deleted save sets that should have been expired based upon the new Browse and
Retention times. After comparing the size of the index directory, prior to and after the modification,
the customer noticed that the index directory decreased in size by several hundred GB. However,
the available space on the Data Domain remained unchanged.
Although NetWorker has deleted the necessary indexes, why does the Data Domain available
capacity remain the same?
