Solution advantages: • Data off-sited as part of the initial backup, good resilience solution, no delays • Part of an Active/Active Data Center disaster recovery solution • Backup load can be split across sites 50:50 - best use of all available resources • No data offsiting costs for physical tape - it is already offsite with this method Solution trade-offs: Company must be willing to invest in multiprotocol routers and DWDN inter site link technology at some cost. Combining D2D and VLS in an End-to-end Solution for ROBO/Regional DCs and Main Data Center using HP Data Protector Company requirements: Protect data anywhere mentality - bring all data home to the main data center. Use the right technology at the right price for the right location. Solution: HP D2D in remote offices and regional data centers. VLS in regional data centers and main data center. All with deduplication and replication enabled. Caveats: Sizing replication target size and links is critical; use the HP Backup Sizer. This solution needs a very structured implementation. ISVs: HP Data Protector has the best integration in this end to end scenario with scripted automated importing of the replicated data cartridges at the regional data centers and main data centers. Device configuration highlights: Probably single VTL configured on D2D at remote sites , four slot mappings per D2D virtual library is possible at regional data center. VLS at regional data center should have one library dedicated to accepting data from D2D at regional data center. Regional data center and main data center use of VLS units as local backup resources should be deployed to provide as many parallel backup paths as possible. Backup application configuration highlights: D2D units are polled (scripted) by HP Data protector for recently replicated cartridges, VLS units email Data Protector for recently replicated cartridges. Both of these trigger an automated catalog import at the replication target sites (HP unique feature). Figure 34 Using D2D and VLS in ROBO/RDC/MDC Environments Recovery options: As with all replication solutions using D2D andVLS, under normal situation data is recoverable from local D2D or VLS. If retention period has expired it may be on physical tape VLS Blueprints 77

•

•

•
No data offsiting costs for physical tape – it is already offsite with this method
Solution trade-offs
: Company must be willing to invest in multiprotocol routers and DWDN inter
site link technology at some cost.

Company requirements:
Protect data anywhere mentality – bring all data home to the main data
center. Use the right technology at the right price for the right location.
Solution
: HP D2D in remote offices and regional data centers. VLS in regional data centers and
main data center. All with deduplication and replication enabled.
Caveats
: Sizing replication target size and links is critical; use the HP Backup Sizer. This solution
needs a very structured implementation.
ISVs
: HP Data Protector has the best integration in this end to end scenario with scripted automated
importing of the replicated data cartridges at the regional data centers and main data centers.
Device configuration highlights
: Probably single VTL configured on D2D at remote sites , four slot

should have one library dedicated to accepting data from D2D at regional data center. Regional
data center and main data center use of VLS units as local backup resources should be deployed
to provide as many parallel backup paths as possible.
Backup application configuration highlights
: D2D units are polled (scripted) by HP Data protector
for recently replicated cartridges, VLS units email Data Protector for recently replicated cartridges.
Both of these trigger an automated catalog import at the replication target sites (HP unique feature).
