Assign Snapshot Stores to Specific Data Centers

On this page

  • Overview
  • Prerequisites
  • Procedures

Additional Snapshot Stores can be added to meet storage requirements. These additional stores can be deployed in the same data center as the first store. There are times where these stores need to be deployed to other data centers due to either network performance issues or regulatory requirements.

You can bind specific Ops Manager projects to specific snapshot stores and particular data centers. This assigns the backups of particular MongoDB deployments to specific data centers.

Note

You can bind only projects to specific snapshot stores or data centers. You cannot bind shards to a specific location.

Diagram showing the flow of data for Ops Manager's backup components when using two Data Centers.

This tutorial sets up two snapshot stores, one in each of two separate data centers, and attaches a separate project to each.

  • Configure the two Ops Manager Application instances to share a single dedicated Ops Manager Application Database.

    • The members of the Ops Manager Application Database replica set can be put in each data center.

  • Configure each Backup to use the URL for its local Ops Manager Application.

    • Each Ops Manager Application can use a different hostname or a split-horizon DNS to point each agent to its local Ops Manager Application.

Note

The Ops Manager Application Database and the backup blockstore databases are MongoDB databases and can run as standalones or replica sets.

For production deployments, use replica sets to provide database high availability.

Each data center must host its own backup blockstore database or File System Store, Ops Manager Application and MongoDB Agent with Backup.

Each server must meet the cumulative hardware and software requirements for the components it runs. See Ops Manager System Requirements.

All servers running Backup and Ops Manager Application Databases use MongoDB. They must meet the configuration requirements in the MongoDB Production Notes.

Install MongoDB on the servers that host the:

  • Ops Manager Application database

  • Blockstore databases

See Install MongoDB in the MongoDB manual to find the correct install procedure for your operating system.

To run replica sets for the Ops Manager Application database and blockstore databases, see Deploy a Replica Set in the MongoDB manual.

Install the Ops Manager Application in each data center.

Note

See Install Ops Manager for instructions for your operating system.

Important

Each set of installation instructions for each operating system covers how to create a multiple instances of an Ops Manager Application. These activities need to be completed before binding projects to the backup resources.
