Server DR protection storage types

PowerProtect Data Manager supports two types of protection storage for server DR: NFS and DD Boost.

DD Boost is the recommended storage type for PowerProtect Data Manager server DR. NFS is the legacy storage type for PowerProtect Data Manager server DR.

Updating the PowerProtect Data Manager server does not automatically change the storage type. Instead, select the appropriate storage type and manually configure server DR backups. Do not alternate between storage types.

Switching from NFS to DD Boost creates new server DR backups, rather than migrating existing backups. The previous NFS backups are no longer visible in the list of DR backups. However, you can still recover from older NFS server DR backups even after switching to DD Boost, should you experience a disaster before the initial DD Boost system backup completes.

DD Boost

DD Boost provides security and efficiency advantages over NFS, including password-protected authentication. When you use DD Boost, PowerProtect Data Manager creates and manages a storage unit on the DD system and a corresponding user account.

  • The storage unit and user account name are based on the PowerProtect Data Manager hostname. For example, SysDR_<hostname>.
  • The DD Boost user password is based on the PowerProtect Data Manager predefined administrator account (admin) password.
    NOTE The password is based on the admin account even if you use other accounts with the Administrator role, such as external identity provider users, to administer PowerProtect Data Manager.

Changes to the PowerProtect Data Manager predefined administrator password prompt corresponding updates to the DD Boost user password. If you configured server DR replication, password changes also prompt corresponding updates to the credentials on the replication target. Recovery from server DR backups requires the PowerProtect Data Manager predefined administrator password. If you do not know this password, contact Customer Support.

If you plan to use DD Boost, add the DD system as protection storage before you configure server DR. Protection storage provides instructions.

The DD Boost storage type allows for automatic server DR configuration. Automatic server DR provides more information.

Only the DD Boost storage type supports server DR replication.

NFS

To store backups over NFS, you must configure and assign a private storage unit for the PowerProtect Data Manager system. Then, prepare the DD recovery target by creating an NFS export. With the DD system address and the NFS export path, you can configure PowerProtect Data Manager to perform server DR backups.

NFS storage is deprecated in favor of DD Boost.
