Ans: The following are the key features of CommVault;
Ans: There are various ways of performing high availability in CommVault;

Ans: We will have the data as one primary copy to which there will be secondary copies. We can create three types of secondary copies,
Ans: CommServe DR is hardware fresh which consists of Copy DR sets this provides CommServe facilities and restores the CS DR procedures.
Ans: This global duplication policy enables the data duplication across the multiple storage sets of disk libraries and database servers (DDB).
Ans: The following factors will give a brief explanation of DDB:
Ans: There are 3 building blocks of the CommCell environment;
Ans: The benefits of a proxy server such as;
Ans: We can perform backup on VMWare from a subclient. The entities that get backed up are,

Ans: The default block size for the data duplication is 128kb.
Synthetic full: Synthetic full backup consolidates all the data incremental backups and appends the last backup data. Here the server (server is nothing but client machine or network utilization) performs very low utilization when compared to Full back up.
Full Backup: this full backup performs full utilization operation which is taken from the server.
Dash Full: this dash full performs operations like copying the unique blocks of the de-duplicate data, updates the DDB data, and also index the backup data.
Ans: A silo is the collection of disk volume data folders that are associated with the DDB (De-Duplicate database). It contains the deduplicated data that is pre-written on the disk storage.
Ans:The following are the different backups available in CommVault;
Ans: The different types of transfer modes are such as;
Ans:Simpana is indeed one of the capabilities of Commvault's enterprise backup software platform specifically built for backup, archiving, and analysis of data. Simpana is a modern variant of the method of deduplication implemented by Commvault.

The steps are as follows;
Ans: Intellisnap backup is used to create a point-in-time snapshot of the data. It is mainly used for taking backup of live data and then continuing the live operations.
Ans: IntelliSnap recovery manager (IRM) is used to execute hardware storage systems snapshots into a recovery process with no effect on the production server. It also provides a centralized configuration wizard through which we can configure storage media, policies, etc.
Ans: The below-mentioned steps will help you perform a VM ware backup:

Ans: There are two possible ways available to restore the data using CommServe;
Ans: The global deduplication policy furnishes a common deduplication database(DDB) that can be shared by various storage policy copies. It allows the deduplication of data from multiple copies which results in removing redundant data.
