Title
Understanding Front-End Terebytes in NetVault SmartDisk -
Description
What is a front end terabyte in NetVault SmartDisk? -
Cause
NetVault SmartDisk is licensed by front-end terabytes (TBs). A front-end TB is the aggregate amount of data thatyou want NetVault SmartDisk to protect from all source or client machines that are targeting a single NetVaultSmartDisk Instance. A front-end TB is measured by the amount of storage capacity occupied on the sourcestorage by files that are to be backed up; this measurement is based on the capacity consumed before datareduction that might be achieved by using the optional NetVault SmartDisk Deduplication Option. Front-endsource data can include OS-related data, file system data, database data, application data, and so on. -
Resolution
Because a front-end TB is the total amount of data that you intend to back up from all client or source storagedevices, it helps you determine how much data you back up to NetVault SmartDisk. Front-end TBs are onlycounted once; it does not matter how many times you back up the same set of data or how long you retain eachversion of the backup data.NOTE: Only the data from a source machine that is being sent to NetVault SmartDisk must be included inthe licensed capacity. If you are targeting other devices, such as real tape media, for some of the dataresiding on a source machine, that data does not count towards front-end capacity for NetVault SmartDisklicensing.NetVault SmartDisk can accept backup data from multiple servers. You can also deploy multiple NetVaultSmartDisk Instances, which can act as targets for clients connected to multiple servers. When calculating the licensed capacity for a NetVault SmartDisk Instance, you must include the capacity across all clients or sourcestargeting that NetVault SmartDisk Instance.NetVault SmartDisk Licensed Capacity is not based on the following:• The actual size of the Storage Pool, Staging Store, or Chunk Store.• The actual size of the backups after deduplication.• Retention period of data stored in NetVault SmartDisk.• Number of copies residing in NetVault SmartDisk Instances.This information can be found in the NetVault Smartdisk installation guide.https://support.quest.com/technical-documents/netvault-smartdisk/10.0.1/installation-guide
