Understand the Veeam Scale-Out Backup Repository

The Veeam Scale-out Backup Repository provides horizontal-scaling support for storing data in multiple tiers. This repository contains one or more backup repositories called performance extents, and it can be expanded with cloud-based repositories or local object repositories.

All the storage devices and systems in the scale-out backup repository are joined into a system. This feature:

• Provides a convenient way to manage backup storage.
• Provides an easy way to extend repositories, by adding a performance extent to the existing repository. You can expand the scale-out backup repository at any time.
• Supports any backup target that Veeam supports: Windows or Linux servers with block volumes, File Storage as a network share. All the features of any storage device or system are preserved.
• Lets you set up a granular performance policy.
• Provides nearly unlimited cloud-based storage capacity by using Object Storage to offload data from extents to the cloud for long-term storage.

To deploy a scale-out backup repository, you need to first configure several backup repositories. As explained in the earlier topics, you can use the Block Volume and File Storage services as performance extents (in the performance tier), and you can use Object Storage as a capacity tier.

• The performance tier of a scale-out backup repository is used for fast access to data and can contain one or more performance extents. For more information, see "Performance Tier" in the Veeam Backup & Replication User Guide for VMware vSphere.
• The capacity tier is an extra tier of storage that can be attached to a scale-out backup repository. Data can be transported from the scale-out backup repository performance extents to the capacity tier for long-term storage. For more information, see "Capacity Tier" in the Veeam Backup & Replication User Guide for VMware vSphere.
