What is Partial Backup?- A partial backup is similar to a full database backup, but a it does not contain all the filegroups.
- It contains all the data in the primary filegroup, every read/write filegroup, and any optionally-specified read-only files.
- A partial backup is any operating system backup short of a full backup, taken while the database is open or shut down.
The following are all examples of partial database backups:
a. Backup of all datafiles for an individual tablespace.
b. Backup of a single datafile.
c. Backup of a control file.
- They are only useful for a database operating in ARCHIVELOG mode, because an archived redo log is present, the datafiles restored from a partial backup can be made consistent with the rest of the database during recovery procedures.
