arcserve-KB : How to Migrate D2D r16.5 Backup Data of 2 Nodes with Same Host Name to RPS Data Store

Last Update: 2015-09-14 07:28:00 UTC

If there are 2 servers have same host name, but DNS names are different. You can follow steps below to migrate them to the same data store. On data store, each server with UDP agent installed will have a unique ID allocated and won’t cause conflict.

You should migrate backups of these 2 servers to same RPS data store in 2 steps – assuming you have 2 servers A1 and A2, and they have same host name but FQDN are not same (for example, A.domain1.com and A.domain1.com).

Assuming you have a Console server C, and a RPS server R; RPS server R is managed by C; there is a data store D configured on RPS server R.

  1. Step 1, migrate recovery points of server A1 to data store D.
    1. Follow the doc How to Migrate Arcserve r16.5 Recovery Points to Arcserve UDP to migrate backup data of server A1 to data store D on RPS server R.
    2. Installing Arcserve UDP agent v5 Update 2 on server A1.
    3. Add A1 to Console server C for management.
    4. Create a plan P1, select backup destination as data store D on RPS server R.
    5. Deploy plan P1 to A1. You will find out the recovery point migrated from r16.5 are available in restore UI when browsing from A1 agent UI.
  2. Step2, migrate recovery point of server A2 to data store D
    1. Follow the doc How to Migrate Arcserve r16.5 Recovery Points to Arcserve UDP to migrate backup data of server A.2 to data store.
    2. Installing Arcserve UDP agent v5 Update 2 on server A2.
    3. Add A2 to Console server C for management.
    4. Create a plan P1, select backup destination as data store D on RPS server R.
    5. Connect to A2 using windows remote desktop, open registry editor and go to “HKEY_LOCAL_MACHINE\SOFTWARE\CA\ARCserve Unified Data Protection\Engine”, find the value of “NodeID”, its values is a GUID id. Note down this ID.
    6. Go to the backup destination path of the data store D, find the folder named “A”, here A is the host name, without any GUID appended.
    7. Append the GUID noted down to this folder, and enclose the ID in a pair of brackets. Please do not add any spaces. It should look like

                       A2[eebeb46e-340c-4c60-8dce-b7ddbedd7e80]

            8.  Add this node to the a backup plan and deploy to server A
