An EMC Avamar customer has a backup environment consisting of three multi-node Avamar
servers. You have been asked to help them configure a new Oracle database client for backup. To
achieve acceptable performance for this new client, the customer wants to use multiple RMAN
channels. What is a consideration of this configuration?

An EMC customer is protecting 3000 virtual machines (VMs) with guest level backup. All VMs
reside on the same ESX server. The administrators are concerned with the CPU spike during
backups since Avamar is trying to initiate as many backups as possible.
What is the best practice for preventing this spike in CPU on the ESX server host?

An EMC Avamar customer notices that a client’s Progress Bytes and percentage NewBytes are
not being reported on the Activity Monitor while a backup is in progress. The backup reports
“Completed with Exception(s)” when finished. What is a possible cause for this issue?

A customer has a 1 TB Oracle 10g database on a HP-UX 11.31 client. They have created two
groups that run once every 24 hours. One group is for backing up the database; the other group is
for backing up the file system. During the course of a week, the customer notices that the client is
taking up twice the space as expected. What is a probable cause?

A customer wants to maximize their tapeout throughput with Avamar Tapeout (ATO) by using
concurrent staging servers. The servers consist of one Microsoft Windows-based and one UNIXbased.
The customer configured environment file #1 with the appropriate staging server variables for each
server type involved. Two ATO batch profiles were configured for environment #1 with the
appropriate staging server types. The batch jobs were started concurrently.
What is the expected outcome?

A customer has a EMC Avamar desktop/laptop environment consisting of 100 clients distributed
across three Avamar domains. Compliance requirements mandate that 15 clients with 2 TBs of
data on each must have their backups written to tape. Avamar Data Transport (ADT) with three 2
TB transport nodes will be used to accomplish the tapeout process.
Which changes are required to accommodate this environment?

A customer has four EMC Avamar servers located in a centralized disaster recovery site, each
receiving replicated data from several remote sites. Several client backups are in the range of 1 – 4
TBs per dataset with file counts of 2 – 4 million files. Due to capacity limitations, Avamar retention
value is limited to two months and tapeout is being used to provide extended retention of up to five
years.
The nature of the customer’s business requires frequent lookups of historical data, often beyond
the Avamar 2-month retention period. Therefore, quick recovery of files from tape is required.
Compliance requirements mandate tapeout be performed on a weekly basis. The customer is
considering Avamar Data Transport (ADT) or Avamar Tape Out (ATO).
Which tapeout solution is best suited for this environment?

An EMC Avamar customer has an IBM DB2 server with multiple instances; i.e., A, B, and C.
• Instance A = 150 GB
• Instance B = 300 GB
• Instance C = 75 GB
The customer has installed the Avamar DB2 client plug-in on this host and has configured an
online backup schedule for each instance. Which additional step is required prior to starting the
schedules for each instance?

A customer with an existing EMC NetWorker environment has recently added an Avamar system
to their environment. Avamar enhanced NDMP backup capabilities will be used to backup Celerra.
In addition, the customer has a requirement to write the NDMP backup data from Avamar to tape
on a weekly basis. Avamar Tapeout (ATO), installed on the Avamar utility node, will be used for
this purpose.
Which methods can be used to automatically schedule ATO batch jobs?

An existing EMC Avamar customer has a 7.8 TB single node server. They have started a restore
of a large amount of data to a Microsoft Windows 2008 server. The restore rate is less than what
they were expecting. What should be checked to ensure the restore is running as fast as possible?
