Table 22. Exchange Smart Copy Options
Planning Item Description
Snapshot Creates a snapshot for each volume comprising the original object.
Clone Creates a new volume (clone) for each volume comprising the original object.
Replica Creates a replica for each volume comprising the original object on a PS Series group
configured as a replication partner for the original volumes. If you select Replica,
ASM/ME displays an additional option dialog box described in step 4.
Backup Type Select Copy. This option is the only supported backup type.
User Comments (Optional) Provide text describing the Smart Copy set. This information displays in
the backup document.
Checksum Verification Verifies the integrity of databases in the Smart Copy by using the eseutil.exe
database maintenance utility.
Soft Recovery Brings all databases to a clean shutdown.
NOTE: For Exchange replicas, immediate Soft Recovery is not available.
Location of eseutil.exe If the location of the eseutil.exe utility is not in its default installation as indicated
in the text field, specify the path to its location. (See Microsoft Exchange eseutil.exe
Utility.)
Perform Task Specify the time and method of running Checksum Verification and Soft Recovery.
Select from the following options:
• Immediately after Smart Copy creation—Starts Checksum Verification and Soft
Recovery as soon as Smart Copy creation is complete.
NOTE: This option is not available for Exchange mailbox database
replicas.
• Global Verification Window—use the times that you configured in ASM/ME as
described in Verification Settings.
You can also use this option to change the Global Verification times. You must
specify a minimum period of 3 hours. If you change the Global Verification times,
the changes apply to the local computer only, and affect all other scheduled
verifications.
• On a remote host pre-configured to perform Exchange verification—Schedule
Global Verification on a remote computer. The remote computer must be
configured to run the operation. (See Run Checksum Verification and Soft
Recovery on a Remote Host.)
Checksum Verification and Soft Recovery for Replicas
If the target Smart Copy is a replica of an Exchange component, rather than a snapshot or clone, the Checksum Verification and Soft
Recovery procedure differs. Volume replication is a continuous process and ASM/ME provides options to perform Checksum Verification
and Soft Recovery without disrupting replication.
NOTE:
For Exchange replicas only, the option to perform Checksum Verification is not available immediately after you
create a Smart Copy.
The following Checksum Verification and Soft Recovery options are available during replica Smart Copy operations:
• Clone and Verify—Creates a clone of the replicated volume and performs Checksum Verification only on the clone. This procedure
requires storage capacity on the secondary group that is at least the same size as the replica. (That is, if the replica is 500 GB, you will
need 500 GB of available space.) Use the Group Manager GUI to view and make space available on the secondary group if necessary.
The advantage of using a clone is that it does not disrupt ongoing data replication from the base volume to the replica. The replication
process continues while the clone undergoes Checksum Verification. Soft Recovery runs on the original Smart Copy during a restore
operation.
• Promote and Verify—Temporarily promotes the replica, making it functionally equivalent to the base volume. ASM/ME performs
Checksum Verification and Soft Recovery on the promoted replica.
