Configuring extensible storage locations
IMPORTANT: The DS-System should have exclusive access to the storage locations at all times when it is running.
When you create an extensible storage location, you must assign it to a storage group to help you organize data on the DS-System. If you do not define any storage groups, the newly created storage locations will automatically belong to the <DEFAULT> storage group. The <DEFAULT> storage group cannot be removed from DS-System. Backed up data from the DS-Client will be directed to the selected storage group's extensible storage location(s).
Data backed up to a storage group will be balanced among the group's extensible storage locations. DS-System will automatically balance its data across the available space for each storage location in the same storage group. However, DS-System will not balance data between different storage groups.
NOTE: If you change the extensible storage locations associated with a storage group, only new backup data will be affected. Data that is already in a storage location is not affected.
DS-System can also integrate with NAS storage volumes to use their native snapshot capability when performing the following (read-only) tasks:
• Replication Send
• BLM Archiving
• Disc/Tape – Write to Buffer
• Restore
When a snapshot is used, the DS-System is able to free the backup set lock on the corresponding backup set almost immediately. This can significantly improve performance in high availability environments, since the backup set can continue to receive new backup data and the activity using the snapshot can be configured to process that data on a separate network. You must have a functioning NAS with defined storage volumes and it must be visible to your DS-System on the network.
