Protecting clustered-data ONTAP NetApp file server volumes
You can create a snapshot differential incremental backup of a volume on a NetApp file server that is part of a clustered-data ONTAP configuration (c-mode file server).
Before you begin
- Complete the procedure in Configuring NetApp and IBM Spectrum Protect for snapshot difference incremental backups.
- Ensure that the clustered-data ONTAP environment is correctly set up by the NetApp storage virtual machine administrator.
- IBM Spectrum Protect™ support for snapshot differential incremental backups of clustered-data ONTAP volumes is supported only on NetApp ONTAP 8.2.1 and later versions.
About this task
In a clustered-data ONTAP environment, storage virtual machines (also referred to as data vServers) contain data volumes that can be protected by the backup-archive client.
A storage virtual machine consists of a single infinite volume or one or more flex volumes. Volumes are accessed remotely using file sharing (CIFS on Windows operating systems, NFS on Linux operating systems).
The storage virtual machines are managed by the cluster management filer, which is the physical filer (the c-mode filer) on which the storage virtual machines reside. The backup client is installed on the remote machine that accesses the volumes.
The backup-archive client must be configured with credentials for the NetApp c-mode filers that are being accessed for backup operations.
- The following information is required for this procedure:
- The host name or IP address of the cluster management filer.
- The host name or IP address of the storage virtual machine.
- The storage virtual machine name.
- The cluster management filer credentials (user name and password).
- The cluster management filer user that is configured by
the client must be assigned the ontapapi capability with the role of
admin.
The ontapapi capability does not allow interactive access to the filer with methods such as telnet, ssh, or http/https. No other user capabilities are required to run snapshot differential incremental backups.
Procedure
Complete the following steps on the remote machine where the backup-archive client is installed:
Example
- ONTAP 8.31 management filer
Hostname: netapp1mgmt.example.com User: netapp1mgmt_user Password: pass4netapp1mgmt CIFS Domain Controller: WINDC Domain User: domainuser
- Flex volume storage virtual machine
Hostname: netapp1-v1.example.com Storage virtual machine name: netapp1-client1 CIFS share: demovol Volume name: demovol
- Infinite volume storage virtual machine
Hostname: netapp1-v4.example.com Storage virtual machine name: netapp1-infiniteVolume1 CIFS Share: InfiniteVol
- Configure the client with the management filer credentials by issuing the following
command:
dsmc set password –type=filer netapp1mgmt.example.com netapp1mgmt_user pass4netapp1mgmt
- Define storage virtual machine associations for each storage virtual machine with the following
commands:
dsmc set netappsvm netapp1mgmt.example.com netapp1-v1.example.com netapp1-client1
dsmc set netappsvm netapp1mgmt.example.com netapp1-v4.example.com netapp1-infiniteVolume1
- Map remote volumes to drive letters for each storage virtual machine:
net use y: \\netapp1-v1.example.com\demovol WINDC\domainuser
net use z: \\netapp1-v4.example.com\InfiniteVol WINDC\domainuser
- Run a full progressive incremental backup of the flex volume and infinite
volume:
dsmc incr y: -snapdiff -snapdiffhttps
dsmc incr z: -snapdiff -snapdiffhttps
You need only to run the full progressive incremental backup once. After this backup is successfully completed, run differential backups in future backup operations.
- Run a snapshot differential backup of the flex volume and infinite
volume:
dsmc incr y: -snapdiff -snapdiffhttps
dsmc incr z: -snapdiff -snapdiffhttps
