The following list describes the hosts and devices in a ProtectPoint solution:
Production Host
The host running the production database application. The production host sees
only the production VMAX3 devices.
Recovery Host
The host available for database recovery operations. The recovery host can
include direct access to:
l
A backup on the recovery devices (vDisk devices encapsulated through
FAST.X), or
l
Access to a backup copy of the database on the restore devices (native
VMAX3 devices).
Production Devices
Host devices available to the production host where the database instance
resides. Production devices are the source devices for the TimeFinder/SnapVX
operations that copy the production data to the backup devices for transfer to
the Data Domain.
Restore Devices
Native VMAX3 devices used for full LUN-level copy of a backup to a new set of
devices is desired. Restore devices are masked to the recovery host.
Backup Devices
Targets of the TimeFinder/SnapVX snapshots from the production devices.
Backup devices are VMAX3 thin devices created when the Data Domain vDisk
backup LUNs are encapsulated.
Recovery Devices
VMAX3 devices created when the Data Domain vDisk recovery LUNs are
encapsulated. Recovery devices are presented to the recovery host when the
Application administrator performs an object-level restore of specific database
objects.
ProtectPoint and traditional backup
The ProtectPoint workflow can provide data protection in situations where more
traditional approaches cannot successfully meet the business requirements. This is
often due to small or non-existent backup windows, demanding recovery time
objective (RTO) or recovery point objective (RPO) requirements, or a combination of
both.
