Table 22. Exchange Smart Copy Options Planning Item Snapshot Clone Replica Backup Type User Comments Checksum Verification Soft Recovery Location of eseutil.exe Perform Task Description Creates a snapshot for each volume comprising the original object. Creates a new volume (clone) for each volume comprising the original object. 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. Select Copy. This option is the only supported backup type. (Optional) Provide text describing the Smart Copy set. This information displays in the backup document. Verifies the integrity of databases in the Smart Copy by using the eseutil.exe database maintenance utility. Brings all databases to a clean shutdown. NOTE: For Exchange replicas, immediate Soft Recovery is not available. 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.) 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. Using ASM/ME with Exchange 67
