20120226664 | PARALLEL DATABASE BACKUP AND RESTORE - Embodiments are directed to simultaneously backing up data from multiple locations to a single location and to restoring data from a single location to multiple locations simultaneously. In an embodiment, a computer system receives a backup command from a user which indicates that various specified portions of data are to be backed up. The data portions are stored in multiple different locations in a parallel database. The computer system generates multiple backup commands specific for each location in which the data is stored. The backup commands initiate a parallel backup from the various locations to a single location in a data store. The computer system also executes the generated backup commands in parallel, so that the data from each of the different locations is backed up in the data store. | 09-06-2012 |
