Description

Step 1

Install or upgrade NetBackup.

All master servers and media servers must be at NetBackup version 7.1 or later.

See the NetBackup Installation Guide.

Step 2

Configure the storage devices.

To replicate images from one domain to another requires that suitable storage be configured in each domain. The storage in the originating domain and the storage in the target domain must be of the same type.

The storage can be either of the following types:

  • OpenStorage (OST) appliances whose plug-ins conform to version v11.1 of the OpenStorage API.

    See the NetBackup OpenStorage Solutions Guide for Disk.

  • Media Server Deduplication Pools (MSDP). For MSDP, the plug-in is installed with NetBackup; no separate installation is required.

    To use MSDP, a Media Server Deduplication Pool must be configured in both domains.

    When you configure the disk pool in the target domain, consider using the Limit I/O streams setting in the Maximum I/O Streams section. Doing so can reduce the load on the target storage server.

Note:

For successful replication and import, make sure that the storage appliances work properly in each domain.

Step 3

Configure the storage units.

Configure the storage units in both the originating domain and the target domain.

See Creating a storage unit on UNIX/Linux.

Step 4

Define the relationship between the domains.

Define the relationship between the domains so that the originating domain knows where to send the data.

See About the domain relationship on UNIX/Linux.

Step 5

Configure the storage lifecycle policies.

Configure a pair of storage lifecycle policies; one in each master server domain.

The storage lifecycle policy pair includes:

  • An SLP in the originating domain that contains a replication operation to a target master. (The Auto Image Replication SLP.)

  • An SLP in the target domain that contains an import operation. (The Import SLP.)

The following topic describes how the SLPs must be named and the operations and retention type that each SLP must contain.

See About the storage lifecycle policies required for Auto Image Replication on UNIX/Linux.

Step 6

Configure and run the backup policy in the originating domain.

The backup policy must indicate the configured SLP as the Policy storage selection.
