Using the bprestore command to restore Microsoft Azure Stack VM with modified metadata to an alternate region
NetBackup lets you restore Microsoft Azure Stack data to another resource group and modify the metadata. This type of restore method is also referred to as redirected restores.
To perform redirected restore for Microsoft Azure Stack
- Modify the values for rename_file and listfile as follows:
Parameter
Value
rename_file
Add ALT_APPLICATION_SERVER= entry to specify ARM endpoint of the alternate region
Too update the
VmNamemetadata, add:change
/21c71fdf-3ee5-4b57-8c51-18ebe7032237/SKRG/MSvm15/Metadata/VmName=OldVmNameto
/21c71fdf-3ee5-4b57-8c51-18ebe7032237/SKRG/MSvm15/Metadata/VmName=NewVmNameTo change the power state of the VM, add:
change
/21c71fdf-3ee5-4b57-8c51-18ebe7032237/SKRG/MSvm15/Metadata/PowerState=runningto
/21c71fdf-3ee5-4b57-8c51-18ebe7032237/SKRG/MSvm15/Metadata/PowerState=deallocateThe file paths must start with / (slash).
Add a new entry for all the metadata options that you want to modify.
Note:
For the VM size metadata, specify the modified value in the Microsoft Azure Stack recommended format. The new VM size must be part of your subscription.
For more information, refer to Virtual machine sizes supported in Azure Stack.
listfile
List of all the Microsoft Azure files to be restored
- To fetch the credentials information for the alternate Azure Stack:
Add a tpconfig entry for the new Azure Stack ARM end point.
Change the name of the generated encrypted file in /usr/openv/var/global to match the name of the source client encrypted credentials file.
For example, if
arm-end-point1.confis the encrypted source client file and arm-end-point2.conf is the encrypted alternate client file. Make a copy of arm-end-point1.conf to arm-end-point1.conf_org and then copy arm-end-point2.conf to arm-end-point1.conf before running the bprestore command. - List of files can be obtained by running the following bplist command:
bplist -S master_server -C configuration_server_01 -unix_files -R 3 -t 44 -X -s <bktime> -e <bktime> "/21c71fdf-3ee5-4b57-8c51-18ebe7032237/skrg1/bkvm15" > listfile
Open the
listfilein the editor and remove the special characters at the end of the line. Remove all the paths ending with / that correspond to directories. - Run the following command on the NetBackup master server using the modified values for the mentioned parameters in step 1.
bprestore -S master_server -D backup_host-C client -R rename_file -t 44 -X -s bktime -e bktime -L progress log -f listfile | filenames
Where,
-S master_serverSpecifies the name of the NetBackup master server.
-D backup_hostSpecifies the name of the backup host.
-C clientSpecifies a configuration server as a source to use for finding backups or archives from which to restore files. This name must be as it appears in the NetBackup catalog.
-f listfileSpecifies a file (listfile) that contains a list of files to be restored and can be used instead of the file names option (filenames). In listfile, list each file path must be on a separate line.
-L progress_logSpecifies the name of allowed list file path in which to write progress information.
-t 44Specifies BigData as the policy type.
-R rename_fileSpecifies the name of a file with name changes for alternate-path restores.
