SnapManager from a DBA perspective
SnapManager for Oracle simplifies backing up data in Oracle databases for database administrators (DBA). SnapManager provides the following benefits to database administrators:
◆Creates a backup quickly and in a space-efficient way, which lets you perform more backups
◆Organizes information into a group, such as a profile, to make creating backups and restoring and recovering data quick and easy
◆Automatically maps the database files to the storage. You no longer need to know the underlying storage system
◆Integrates with existing Oracle tools, such as Recovery Manager (RMAN) and Automatic Storage Management (ASM)
◆Creates Snapshot copies of logs
◆Quickly creates a clone of a database
◆Reduces the mean time to recover a database by using SnapRestore
◆Works with Oracle products to enable DBAs to continue using their current tool sets

SnapManager from a storage administrator perspective
SnapManager for Oracle makes managing the storage required for backups easier for a storage administrator. SnapManager provides the following benefits to storage administrators:
◆Handles different protocols (FCP, iSCSI, and NFS)
◆Gives you options to optimize backups based on the type of backup (complete or partial) that works best in your environment
◆Makes backing up databases quick and space-efficient, so you can do them more frequently, if necessary
◆Creates quick and space-efficient clones
◆Works with host volume managers

按照功能的理解，应该是可以发现oracle的checkpoing，获得一致性的快照，然后利用snap进行备份和恢复。
也不知道理解的对不对！
