Backup Exec Continuous Protection Server Key Benefits
Eliminates Backup Windows
Symantec Backup Exec offers the Continuous Protection Server to help ensure that your data is always protected
and available. As a continuous disk‐based data protection solution, CPS notes when a file changes and helps ensure
the change is captured and protected. It only captures granular or block‐level changes, not the whole file, reducing
the impact on network performance. Not only is the most recent data protected, but multiple versions of files are
also captured and available for recovery or retrieval through the use of snapshots. Snapshots represent a specific
point in time of the CPS backup destination. Snapshots can be created manually or scheduled to occur on a periodic
basis within the CPS admin console. Snapshots are retained for a default period of 24 hours unless specified. CPS
integrates with Microsoft Volume Shadow Copy Services (VSS). VSS requires a minimum of 300 MB of space before
any snapshots have been taken. Additional space requirements depend on the size of the data being protected and
the frequency in which the snapshots are occurring. The more frequent the snapshots, the greater the space
requirements will be for storing the snapshots.
Backup Exec continuous data protection helps eliminate the ever‐shrinking backup window faced by organizations
by protecting data whenever a file changes—continuously. This means no more backup window, because IT is not
performing the traditional full, incremental, or differential backups of business‐critical data on file servers. This
simplifies management and reduces costs:
• Protects data immediately and continuously
• No impact on the production business server
• Protects only changed data
• Continuously protects multiple servers simultaneously
