Restoring or retrieving objects on another node

Question & Answer


Can I restore or retrieve files using another node that does not owns the data?


You can take one of the following methods to restore or retrieve files from a different client node.
Assume NodeA is the node which stores the data and NodeB is the node which restores or retrieves the data.
NodeA backs up or archives /home/* data.

[1] Use the fromnode option
1. On NodeA, give NodeB access to all files in the /home directory backed up by NodeA.
dsmc set access backup /home/* NodeB

2. Restore files from NodeB using the fromnode option.
dsmc restore "/home/*" /tmp/work/ -fromnode=NodeA

* You must give NodeB access to files on NodeA in advance of the restore operation.
* The password of NodeA is not required for the restore operation.

[2] Use the asnodename option
1. Grant proxy authority to NodeB on the Tivoli Storage Manager Server administrative command line.
grant proxyynode target=NodeA agent=NodeB

2. Restore objects from NodeB using the asnodename option.
dsmc restore "/home/*" /tmp/work/ -asnodename=NodeA

* You must grant proxy authority using administrative command line in advance of the restore operation.
* No step is required on NodeA.
* The password of NodeA is not required for restore operation.

[3] Use the virtualnodename option
1. Restore objects from NodeB using the virtualnodename option.
dsmc restore "/home/*" /tmp/work/ -virtualnodename=NodeA

* Any pre-configuration is not required.
* The password of NodeA IS required for the restore operation.
