HP StoreOnce 6500 Backup Installation Planning and Preparation Guide

Backup strategy
Your backup strategy will impact upon networking and Fibre Channel decisions.
• To use Virtual Tape, Fibre Channel connectivity is required. To ensure tolerance of a node
outage HP recommends using a backup application that supports path failover.
Please note that the HP Data Protector DFMF (Distributed File Media Format) for Data Protector's
virtual full backups is not supported for use with the StoreOnce Backup System. This format is
very inefficient with deduplication devices. For further details see HP StoreOnce Backup system
Concepts and Configuration guidelines.
• To back up to a NAS target, Ethernet connectivity is required. Backup and replication jobs
will use the same network paths to/from the nodes.
• StoreOnce Replication, available with both VTL and NAS, uses Ethernet connectivity.
• To back up to StoreOnce Catalyst stores, Ethernet connectivity is required. Backup jobs use
the same network paths to/from the appliance. Catalyst copy jobs always use Ethernet
connectivity between StoreOnce applicances. If using Symantec NetBackup or Backup Exec,
the HP StoreOnce Catalyst OST plugin is required. It must be installed on each Media Server
required to write data to the StoreOnce Catalyst stores. The latest version of the OST plugin
is recommended (currently 3.0), OST Plugin 2.1 is a minimum requirement for Backup Exec.
NOTE: Catalyst over Fibre Channel and Federated Catalyst are supported with StoreOnce
software version 3.11.0 and later. These features are not automatically enabledand are not
currently described in this document but they require the HP StoreOnce Catalyst OST 3.0
plugin when using Symantec NetBackup.
• You can use a combination of VTL, NAS shares and StoreOnce Catalyst stores within the same
service set (node).

If creating CIFS shares, will you be using Active Domain (AD) authorization? ...........................
NOTE: If the Backup system is part of an AD domain, it is possible to add external users and
groups on the same domain as StoreOnce users with access to all StoreOnce features.
