You can decrease the time that SnapManager requires to complete a restore operation by making more backup copies and ensuring that any LUN clone split operations in progress are complete.
The more backup operations you perform, the fewer Exchange transaction logs need to be played forward at restore time. At a minimum, you should perform one SnapManager full database backup operation every 24 hours.
Before proceeding with failback to the production site, ensure that any LUN clone split operations that are in progress are complete. The LUN clone split functionality, introduced with Data ONTAP 7.1, supports significantly faster online Snapshot copy restore operation when using SnapManager or SnapDrive to restore databases. By default, this functionality is enabled.
