Disaster recovery for cloud LSU in Flex Scale
When the NetBackup Flex Scale recovers from a site-based disaster, the backup data in cloud LSU can be recovered by disaster recovery of the cloud LSU.
Considerations before disaster recovery of the cloud LSU:
The secondary NetBackup Flex Scale is ready.
For more information, See the Site-based disaster recovery section of the NetBackup Flex Scale Administrator's Guide.
MSDP storage server is ready and configured with the same configuration.
KMS server is ready and key group in KMS server is ready if MSDP KMS encryption is enabled in this cloud LSU.
To perform the disaster recovery for cloud LSU
- If the cloud instance alias does not exist, run the following command to add the alias.
csconfig cldinstance -as -in amazon.com -sts <storageserver> -lsu_name <lsuname>
- On the NetBackup primary server, run the following command to reuse the cloud LSU. Use the same credentials, bucket name, and sub bucket that were used before the disaster recovery.
nbdevconfig -setconfig -storage_server sts_hostname -stype PureDisk -configlist <configuration file>
Sample configuration file:
If MSDP KMS encryption is enabled in this cloud LSU:
V7.5 "operation" "reuse-lsu-cloud" string V7.5 "lsuCloudUser" "XXX" string V7.5 "lsuCloudPassword" "XXX" string V7.5 "lsuCloudAlias" "<storageserver_lsuname>" string V7.5 "lsuCloudBucketName" "XXX" string V7.5 "lsuCloudBucketSubName" "XXX" string V7.5 "lsuKmsServerName" "XXX" string
If MSDP KMS encryption is disabled in this cloud LSU:
V7.5 "operation" "reuse-lsu-cloud" string V7.5 "lsuCloudUser" "XXX" string V7.5 "lsuCloudPassword" "XXX" string V7.5 "lsuCloudAlias" "<storageserver_lsuname>" string V7.5 "lsuCloudBucketName" "XXX" string V7.5 "lsuCloudBucketSubName" "XXX" string
- On the NetBackup primary server, get the storage server name. On the engines container with the storage server name, run the following command to get the catalog from the cloud:
cacontrol --catalog clouddr <lsuname>
Retry this command if it fails for intermittent network issue.
- Restart the cluster.
- Create the disk pool for the cloud LSU.
- Do two-phase import.
