Replicating backup storage data by using Open Snap Store Manager

When you enable cross-replication in the IBM Spectrum® Protect Plus environment, backup data is asynchronously replicated between two IBM Spectrum Protect servers by using Open Snap Store Manager (OSSM). For example, you can replicate backup data from the OSSM storage on a primary site to the OSSM storage on a secondary site and in reverse direction. The data replication is done by IBM Spectrum Protect server by using replication storage rules.

Before you begin

Before you replicate backup data from IBM Spectrum Protect Plus to IBM Spectrum Protect, ensure to complete the following actions on the IBM Spectrum Protect environment:
  1. Ensure that you have installed and configured two IBM Spectrum Protect servers to cross-replicate the data.
  2. Define server-to-server communication on both the servers. For more information, see Establishing communication between two IBM Spectrum Protect servers.
  3. Install OSSM and configure the OSSM services on both the servers.
Restriction: By using OSSM, replication feature is supported for only cross-replication between two IBM Spectrum Protect servers and not supported for multi-target replication.

Procedure

  1. Add sites in IBM Spectrum Protect Plus for both the IBM Spectrum Protect servers. You must have a unique site that is not associated with any other OSSM storage server or any vSnap servers. Each site requires use of at least one VADP proxy. For instructions about how to add a site, see Adding a site.
  2. Add OSSM storage for both the servers. For instructions, see Adding the Open Snap Store Manager server as a backup storage provider.
    Important: If the OSSM storage has been upgraded from IBM Spectrum Protect Plus 10.1.11 and does not have a certificate, delete the device and re-add the OSSM storage server. For instructions, see Adding the Open Snap Store Manager server as a backup storage provider.
  3. Configure storage partner for each OSSM storage server. For the source server, add the target server as a storage partner and vice versa. For instructions, see Configuring backup storage partners for Open Snap Store Manager.
  4. Create SLA policy for both the servers. For instructions, see Creating an SLA policy for VMware backup to the OSSM storage server. To select the target site for both the server SLA, complete the following actions in the navigation panel:
    • For source server SLA policy, click Replication Policy > Backup Storage Replication in the navigation menu and select target server for Target Site.
    • For target server SLA policy, click Replication Policy > Backup Storage Replication in the navigation menu and select source server for Target Site.
  5. Select and assign VMs to both the server SLAs. You can also assign the same VM to both the server SLAs.
    Important: If you assign the same VM to both the server SLAs, the servers cannot be scheduled to back up at the same time.
  6. Run the schedule to back up VMs to both the server SLAs.
  7. To run the replication manually after the first scheduled replication, in the navigation panel, go to Jobs & Operations > Schedule > choose the replication schedule, and then click the icon icon > Start > SLA Policy > select Replicate from the drop-down list.
  8. To run the cross-replication, start the SLA Policy for replication on both the servers at the same time.
