About the Accelerator feature in NetBackup 7. Article: Last Published: Ratings: 4 0. Product s : NetBackup. Solution Requirements and Options 1. The 'Use accelerator' option must be enabled in the policy attributes. Note: The Accelerator feature is not compatible with the following backup options. Here, I want to get specific and describe the VMware Accelerator feature. Reducing the need for full backups By now you know that we essentially can do a full backup once and incremental forever after that, yet still create periodic full backups.
What's happening under the cover involves several key technologies. This is designed so that the backup application informs VMware that a full backup was run and for VMware to keep track of what blocks change until the next backup. In traditional backup approaches, this makes incremental backups much more efficient.
The backup application does not need to enumerate what's changed. It merely has to request from VMware for a list of the blocks that have changed and then capture those. What's cool in NetBackup 7. All the changes since the previous backup are returned to Netbackup. Netbackup also detects deleted blocks via V-Ray and does not copy those blocks! Netbackup performs Synthetic Full backup. Requirements At least Netbackup 7.

ExaGrid is the only storage for backup solution in the market that automatically resynthesizes NetBackup Accelerator backups, maintaining a full copy ready to restore at 20x faster than any other solution, including Veritas appliances.
With a lower cost up front and a lower cost over time, the ExaGrid cost-effective scale-out growth model makes your NetBackup implementation a high-performance, scalable, efficient end-to-end solution. After an initial full backup, backups are completed by only moving the data that has changed since the last backup. Because NetBackup Accelerator only sends incremental changes in a highly intertwined and deduplicated format, it can be very time-consuming to sort and rehydrate in order to restore, boot a VM, or make an offsite tape copy from accelerated backups.
Restores, instant VM recoveries, audit copies, offsite tape copies and all other requests will take hours to days. Backup data is written directly to the landing zone. ExaGrid further processes the NetBackup Accelerator backups to automatically resynthesize all backups into the ExaGrid landing zone so restores are just as fast as if the accelerated backup was a regular full undeduplicated backup on high-speed disk.
ExaGrid is the only solution in the market with this feature. As a result, restore, recovery, and copy times from an ExaGrid system are an order of magnitude faster than solutions that only store deduplicated data. In most cases, ExaGrid is at least 20 times faster for restores than any other solution including Veritas appliances.
