Recovery Manager | (Oracle specific term) An Oracle |
(RMAN) | directs an Oracle Server process to back up, restore, or recover |
| the database it is connected to. RMAN uses either the recovery |
| catalog or the control file to store information about backups. |
| This information can be used later in restore sessions. |
recycle | A process that removes the data protection from all backed up |
| data on a medium, allowing Data Protector to overwrite it during |
| one of the next backups. Data that belongs to the same session(s) |
| but resides on other media is also unprotected. Recycling does |
| not actually alter the data on the medium. |
redo log | (Oracle specific term) Every Oracle database has a set of two |
| or more redo log files. The set of redo log files for the database |
| is known as the database's redo log. Oracle uses the redo log |

| associated with the data format. |
replica | (ZDB specific term) An image, at a particular point in time, of |
| the data in source volumes that contain |
| objects. Depending on the hardware or software with which it |
| is created, the image may be an independent exact duplicate |
| (clone) of the storage blocks at the physical disk level (for |
| example, a split mirror or snapclone), or a virtual copy (for |
| example, a snapshot). From perspective of a basic operating |
| system, the complete physical disk containing backup objects |
