Protection for clustered-data ONTAP NetApp file server volumes
You can create a snapshot-differential-incremental backup of a volume that is on a NetApp file server that is part of a clustered-data ONTAP configuration (c-mode file server). Use the set password command to specify the host name of the cluster management server and the credentials that are required to access its volumes. The process to specify the host name for a c-mode file server is the same for a 7-mode file server.
You must also associate a storage virtual machine (SVM) host name with a cluster management server and with the SVM name that the NetApp SVM administrator assigns to the storage virtual machine. Data can be protected on infinite or flexible volumes. The volumes can be SAN-attached volumes or NAS-attached.
- The host name, or IP address, of the storage virtual machine that mounts the volumes.
- The host name, or IP address, of the cluster management server. You must use the same host name or IP address that you used on the backup-archive client set password command when you set the credentials for logging on to the cluster management server.
- The name of the SVM that manages the volumes and logical interfaces (LIFs) for the volumes that
you want to protect. Contact the SVM administrator to determine which data SVM name to use for a
particular storage virtual machine. Note: NetApp formerly called the data SVM the data Vserver.
The set netappsvm command is typically entered only once. The parameters are stored and are used the next time that you back up a clustered volume that is managed by the storage virtual machine. If you move a storage virtual machine to another cluster management server, you must enter the set netappsvm command again and specify the new cluster management server. If necessary, change the login credentials by using the set password command.
Scenario
- A CIFS share exists for the datavol volume; the CIFS share name is also named datavol.
- An active directory server to use to authenticate access to the CIFS shares. The Active Directory server host name is ad1.example.com.
- Map a drive to the
share:
where:net use z: \\vmstghost1.example.com\datavol /u:ad1.example.com\domain_user
domain_user is the name of a user account in the example.com domain.
- Enter the set netappsvm command to associate the logon credentials for a
cluster management server with an SVM, so the backup-archive client can access the volumes that are
managed by the SVM:
dsmc set netappsvm vmstghost1.example.com cms.example.com svm1
where:- vmstghost1.example.com
- Is the host name of the storage virtual machine that has the mounted volume. This is the server that was specified on the net use command example in step 1 .
- cms.example.com
- Is the host name of a cluster management server.
- svm1
- Is the name that the SVM administrator assigned to the storage virtual machine that was specified by the first parameter. In this example, it is the name that the SVM administrator assigned to vmstghost1.example.com.
- By default, HTTP access to the NetApp file server is disabled. If you did not configure your file server to allow access by using HTTP, use the backup-archive client snapdiffhttps option to enable access to the cluster management server, by using the HTTPS protocol.
- Start a snapshot differential incremental backup of the share. If you want to use HTTPS to
connect to the file server, you must specify the backup-archive client
snapdiffhttps option:
dsmc incr z: -snapdiff -snapdiffhttps
The output of the command lists the results of the backup operation:
