SnapProtect - SnapProtect for Open Systems - Getting Started – NetApp

Array Licenses

  • FCP, iSCSI licenses for features such as Fibre Channel and iSCSI protocols. Use the appropriate license for the specific data types
  • HTTP/HTTPS licenses on the destination NetApp file server for communication
  • The NetApp license requirements
    • SnapVault Secondary License for backup and recovery operations (NetApp 7.x and 8.1.x)
    • SnapVault License for backup and recovery operations (NetApp 8.2 and later)
  • Install Operations Manager, Provisioning Manager, and Protection Manager licenses for OnCommand Unified Manager

Array Software

  • Install NetApp filers 7-Mode ONTAP 7.x , ONTAP 8.x
  • Install OnCommand Unified Manager 5.2, no support for OnCommand 6.0 or later. Configure OnCommand Unified Manager and its components.
  • Configure the SnapVault, a NetApp replication technology used for backup and recovery
  • If you plan to use proxy and client computers to mount snapshots, configure the iSCS initiator on the client and proxy computers to access the snapshot device. If you plan to use only the proxy computer to mount snapshots, you can configure the iSCSI initiator on the proxy only.

SnapProtect Software

  • Install SnapProtect 10.0 SP4 or later
  • Install MediaAgent on any client computer whose data will be backed up using SnapProtect for Open Systems
  • Install SnapProtect Qsnap Driver, or Linux LVM, or Veritas VxvM on UNIX clients. The source for the backup is from a device that is either a qsnap device or a Linux LVM or a Veritas VxvM volume
  • To perform the root volume snap in Linux LVM, set the additional setting sEnableRootSnap to "Yes".

Storage Space Requirements

UNIX - Space Requirements for Volume Group

You must have 10% of the volume size with free space to avoid snapshot failures. To increase the COW cache size, configure the nSnapCowSizeMB additional setting. For instructions on adding the additional setting, see Add or Modify an Additional Setting.

Windows - VSS Storage Space for Snapshot

You must set the initial storage space (minimum storage space) using the registry key MinDiffAreaFileSize. No maximum storage space is required. For more information on MinDiffAreaFileSize and requirements for specific Windows versions, refer to the Microsoft Windows Dev Center article Registry Keys and Values for Backup and Restore.

Additional Requirements

  • The following ports must be available on the source client whose data is protected.

    Port 10000: This port is used by the NDMPListener thread for interaction with the OnCommand Unified Manager server.

    Port 10566: Port through which data gets transferred to the destination filer as part of the SnapProtect for Open Systems job. During a Snap Backup job, the SnapProtect for Open Systems listener/agent is triggered for the copy initiation from the destination file server.

    This also implies that only a single instance of a SnapProtect for Open Systems install is supported. Any other products that use these ports might affect the functionality of SnapProtect for Open Systems backups.

  • Install the Workflow Engine. See more information about Workflow Engine.


Perform the following steps before using SnapProtect:

  • If you are using NetApp 7.x or 8.1.x:
  1. On your destination file server, use the license command to check the sv_windows_pri, and sv_linux_pri and sv_unix_pri licenses are available for the secondary file servers
  • If you are using NetApp 8.2.x:
  1. On your destination file server, use the license command to check the SnapVault license is installed for the secondary file servers
  2. Enable SnapVault on the secondary file servers as shown below
