Restoration of data from the file system
Before you restore data from an alternate location, you must restore the necessary file system and mount it on the local host.
You can invoke the restore operation from an alternate location to copy the files from alternate file systems to active file systems.
To perform this operation, you must specify the alternate mount points from which to restore the original mount points and the original Snapshot copy names by creating a restore specification file.
|The Snapshot copy name is a necessary component because the same file system might be snapped multiple times in a single backup operation (for example, once for the data files and once for the log file).|
For Automatic Storage Management (ASM), the disk group name must be same as the disk group that SnapManager cloned to register the backup with Oracle Recovery Manager (RMAN). This name can be obtained by viewing the backup properties.
