Types of backup supported for Oracle databases

Backup type specifies the type of backup that you want to create. SnapCenter supports online and offline backup types for Oracle databases.

Online backup

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:

  • Data files and control files only

  • Archive log files only (the database is not brought to backup mode in this scenario)

  • Full database that includes data files, control files, and archive log files

Offline backup

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 data files and control files in offline backups. You can create either an offline mount or offline shutdown backup.

  • When creating an offline mount backup, you must ensure that the database is in a mounted state.

    If the database is in any other state, the backup operation fails.

  • When creating an offline shutdown backup, the database can be in any state.

    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.
