Backup type specifies the type of backup that you want to create. SnapCenter supports online and offline backup types for Oracle databases.
A backup that is created when the database is in the online state is called an online backup. Also called a hot backup, an online backup enables you to create a backup of the database without shutting it down.
As part of online backup, you can create a backup of the following files:
A backup created when the database is either in a mounted or shutdown state is called an offline backup. An offline backup is also called a cold backup. You can include only datafiles and control files in offline backups. You can create either an offline mount or offline shutdown backup.
If the database is in any other state, the backup operation fails.
The database state is changed to the required state to create a backup. After creating the backup, the database state is reverted to the original state.
