CommVault Professional: Module 2: Deduplication

What is the purpose of Commvault deduplication?

• To store duplicate data on disk or tape

• To reduce the amount of space needed to save and protect data

• To increase the storage and network resource requirements

• To copy data to off-site locations efficiently

What are the benefits of Commvault deduplication?

• Efficient use of storage media

• Efficient use of network bandwidth

• Fast Synthetic Full operations

• All of the above

How does client-side deduplication reduce network bandwidth requirements?

• By sending only changed blocks over the network

• By sending full backup data over the network

• By compressing data before sending over the network

• By encrypting data before sending over the network

What is the purpose of Synthetic Full backup?

• To copy previously backed up data into a new full backup job

• To reduce the time to perform full backup operations

• To copy deduplicated data to tape, disk, or a cloud environment

• To efficiently move large amounts of data

What are DASH Copy operations used for?

• To efficiently copy data to off-site locations

• To perform read-optimized Synthetic Full operations

• To send only modified blocks to a second disk target

• To restore deduplicated data during unforeseen events

What is the purpose of resilient indexing and restoration?

• To efficiently use storage media

• To efficiently use network bandwidth

• To ensure deduplicated data is restored during disaster recovery

• To reduce the time to perform Synthetic Full operations

What is the process of Commvault deduplication?

• Data is read from the source location and written into a memory buffer

• A signature is generated on the data block

• The signature is compared in the DDB to determine if the data block already exists

• All of the above

What is the purpose of partitioned deduplication using NAS storage?

• To recover data even if one MediaAgent is not available

• To provide higher scalability

• To ensure resiliency during data protection jobs

• To enable deduplication for primary storage

When can deduplication be enabled for storage?

• During the storage initial configuration

• After the storage has been configured

• During the backup job configuration

• During the restore operation

What should be considered when configuring deduplication for storage?

• The location of the deduplication database (DDB)

• The type of storage connectivity (local or network)

• The size of the storage target

• The number of MediaAgents sharing the storage unit
