You can back up online or offline Oracle RAC databases, log files, or Oracle datafiles and tablespaces. If the database must be accessible and you have a small backup window, run a series of online backups for different database portions.
You can run backups immediately or configure a schedule for the subclient.
Full Backups
Oracle full backups include the entire database and the control file. If the database is using Transparent Data Encryption (TDE) and using file-based Oracle Wallet, the wallet files are automatically backed up as part of a full database backup.
A full backup is the most comprehensive backup and is the baseline for incremental backups. Full backups of online databases include the log files. An offline full backup is a cold backup for Oracle databases.
Incremental Backups
An Oracle incremental backup contains the changed data from the last full backup. Incremental backups use less media and resources than full backups.
A cumulative backup backs up all blocks changed after the most recent incremental level 0 backup.
