Replicating NAS nodes

You can replicate a NAS node that uses NDMP for backup operations. Before you configure the replication operation, review the restrictions that apply.

About this task

Restrictions:
  • The backup data must be in a storage pool with the NATIVE data format. You cannot replicate backup data in storage pools that have the following data formats:
    • NETAPPDUMP
    • CELERRADUMP
    • NDMPDUMP
  • A differential backup can be replicated only if its full backup is replicated.

Procedure

  1. Enable the NAS node for replication by issuing the UPDATE NODE command:
    update node node_name replstate=enabled
    where node_name specifies the name of the NAS node.
  2. Replicate the node by issuing the REPLICATE NODE command:
    replicate node node_name
    where node_name specifies the name of the NAS node.
  3. To ensure that the replicated data can be restored, define a data mover on the target server for the node by issuing the DEFINE DATAMOVER command:
    define datamover node_name type=nas hladdress=hl_address lladdress=ll_address
        userid=user_id password=user_password dataformat=netappdump
    where:
    node_name
    Specifies the name of the NAS node.
    hl_address
    Specifies either the numerical IP address or the domain name that is used to access the NAS file server.
    ll_address
    Specifies the TCP port number to access the NAS device for NDMP sessions.
    user_id
    Specifies the ID of a user who is authorized to initiate an NDMP session with the NAS file server.
    user_password
    Specifies the password of the user who is authorized to initiate an NDMP session with the NAS file server.

Results

The format of the backup data does not change during the replication process. If backup data is replicated, its associated table of contents is also replicated.
