13 TR1059 | V4.0 | Exchange 2013 Data Protection with EqualLogic Auto-Snapshot Manager/Microsoft Edition 4.6 and PS
Series Arrays
With ASM/ME, smart copy clones can be used for restoring to an Exchange Recovery Mailbox Database
allowing Brick / Item level restores, or create exact copies of Database environments for testing and
development scenarios.
5.5 Replica Smart Copy
Replicas can be used to offload Smart Copy storage as well as checksum and soft recovery operations to
the remote site.
Note: Replicas cannot be used to restore the original volume (Restore All).
Replica Smart Copy options are available if replication is configured in the PS Series group for the volume
or volumes that make up an Exchange Server Database(s). Replicas are point in time copies that are sent
from a primary site and stored on a replication partner. The first replication process will always be a
complete copy of the base volume. Subsequent replication operations will only send the changes since
the last replication operation. When using replica Smart Copies it is important to manage ASM/ME’s
backup documents so that they can be used to recover replicas.
To replicate many Databases and volumes, make sure to configure sufficient replication space. For more
information on PS Series replication and sizing replication space, see the Dell EqualLogic Technical Report,

5.6 Smart Copy Schedules
You can create schedules to create Smart Copy sets at various intervals (Figure 4). The ASM/ME scheduler
is based on the Microsoft Windows schedule service and supports Smart Copy schedule period as often as
5 minutes apart. ASM/ME also supports a “keep count” parameter that retains only the specified number of
active Smart Copies for an object. This ensures that storage resources are maintained while data recovery
remains highly available. You can create schedules by right-clicking an object or using the Actions pane of
ASM/ME. See Appendix B – Command Line Options
for instructions on creating schedules in a script.
Note: ASM/ME and Windows scheduling service can process only one scheduled task at a time. A
scheduled Smart Copy operation may fail if there is another Smart Copy process occurring at the same
time on a server system.
