NetVault SmartDisk: at a glance

NetVault SmartDisk’s disk-based backup and data-deduplication option reduces storage costs with its powerful byte-level, variable-block-based software deduplication, which packs up to 12 times more protected data into the same storage area for a 92 percent reduction in storage footprint. Hardware costs are reduced by using existing storage infrastructure instead of requiring specific drives or appliances. Integration with other Quest Data Protection products, such as NetVault® Backup and vRanger®, speeds deployment while simplified ease-of-use reduces the level of storage expertise required to perform deduplicated disk-based backups.

To shrink backup windows with no additional affect on protected-server resources, you can schedule NetVault SmartDisk’s post-process deduplication option outside the backup window.

With NetVault SmartDisk, you have more choices, including the ability to deploy multiple NetVault SmartDisk Instances to improve load balancing and performance; copy or move data between NetVault SmartDisk Instances, to VTL, or to tape-based devices to place redundant backups in offsite locations for failover and disaster-recovery purposes.

Key benefits

•
Reduces storage costs: NetVault SmartDisk reduces storage costs with its byte-level, variable-block-based deduplication option. This option packs up to 12 times more protected data into the same storage area. It accomplishes this optimization by analyzing smaller amounts of data, thus avoiding the problem that occurs when fixed blocks mask changes and store duplicate data as unique.
NetVault SmartDisk is hardware-agnostic and works on most file systems, so hardware costs are reduced by using the existing storage infrastructure instead of requiring you to acquire specific drives or appliances. The ability to add more file-system paths to NetVault SmartDisk Storage Pools reduces costs by deferring storage expenditures into budget periods when costs are lower or budget restraints may be eased and also ensures that storage does not sit unused.
Data stored in NetVault SmartDisk can have individual retention policies, which gives you the flexibility to store the most recent copies on disk and move older data to an offsite location or to less expensive storage. This option provides a foundation for Lifecycle Management, which further reduces costs with tiered-storage deployments.
•
Shrinks backup windows: To shrink backup windows with no additional affect on protected-server resources, you can schedule NetVault SmartDisk’s post-process deduplication option outside the backup window.
Even if you do not use the optional NetVault SmartDisk deduplication feature, you still receive all the advantages of disk-based backup. For example, you can perform more simultaneous backups with disk than you can by writing backups to tape in a serial process. Completing your backups faster ensures that the performance of the application, database, and files servers is not impacted during business hours by overrunning backup windows.
•
Maximizes flexibility: You can deploy multiple NetVault SmartDisk Instances to distribute network, disk, and deduplication resources, which improves load balancing and performance. Shared-storage support lets you share disk-based backup storage across heterogeneous platforms, which provides a single data-protection solution.
•
Speeds restores: NetVault SmartDisk improves restore times because the data is coming from random-access storage without having to find and mount tapes, and then search for the correct tape position. Most restore requests come in the first 14 to 30 days after backup. With disk-based backup, you can minimize downtime with shorter Recovery Time Objectives, and you can focus on other critical tasks.
