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:
- Ensure that you have installed and configured two IBM Spectrum
Protect servers to cross-replicate the data.
- Define server-to-server communication on both the servers. For more
information, see Establishing communication between two IBM Spectrum Protect servers.
- 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
- 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.
- Add OSSM storage for both the
servers. For instructions, see Adding the Open Snap Store Manager server as a backup storage provider.
- 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.
- 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.
- 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.
- Run the schedule to back up VMs to both the server SLAs.
- 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
>
Start > SLA Policy > select
Replicate from the drop-down list.
- To run the cross-replication, start the SLA Policy for replication
on both the servers at the same time.
