Before you perform a SnapManager backup, you need to gather the information required to complete the backup operation.
Although it is possible to restore from an unverified backup, it is advisable to restore only from verified backups.
If you do not select automatic backup deletion, backups that are created after the current backup are retained.
If you do not need to retain up-to-the-minute restore ability from a backup that is not the most recent, you can reduce the amount of disk space required by omitting the backup of transaction logs that Exchange truncates after the SnapManager Backup operation finishes.
By default, automatic deletion of older backups within a backup management group is done selectively, in such a way that it does not cause a break in the continuity of transaction logs between the previous backup and the present time.
However, if you do not need to retain up-to-the-minute restore ability from a backup that is not the most recent, you can allow the automatic deletion feature to delete all older backups within the backup management group. The storage system space consumption reduces.
If you choose not to retain up-to-the-minute restore ability, it reduces the amount of disk space consumed by transaction log backups that Exchange truncates after the backup finishes. If all backups have the same backup management group designation, not retaining up-to-the-minute restore ability has no effect.
When you use the unique naming convention, the most recent Snapshot copy is identified by the most recent date and time. When you use the generic backup naming convention, the most recent Snapshot copy is identified by the Snapshot copy name that includes the string recent.
When you rename a Storage Group, all the databases in that Storage Group need to be unmounted. After you unmount all the databases, you can remount the databases. At this point Exchange recognizes the new Storage Group name, and you can create new SnapManager backups of this Storage Group. Refresh the backup window before the backup operation.
