How to recover a standby database using incremental RMAN?

For this, perform the following steps: From the primary side, use the backup incremental from scn command and provide the scn value taken from the standby database to take a backup of the changes made after the specified scn value: Switch to the standby database and register the incremental backup using the catalog command:

What is the system change number in RMAN?

Each data block in a datafile contains a system change number (SCN), which is the SCN at which the most recent change was made to the block. During an incremental backup, RMAN reads the SCN of each data block in the input file and compares it to the checkpoint SCN of the parent incremental backup.

When to use RMAN for an inconsistent backup?

An inconsistent backup requires recovery to become consistent. The goal of an incremental backup is to back up only those data blocks that have changed since a previous backup. You can use RMAN to create incremental backups of datafiles, tablespaces, or the whole database.
