APPARATUS AND METHOD FOR DATA BACKUP |
摘要 |
A targeting storage component selects a target virtual disk for one of a full copy or an incremental copy of first data. A periodic backup component triggers a periodic point-in-time copy of the first data to a virtual disk in the cascade. A testing component tests a status of the full copy, the incremental copy and the periodic point-in-time copy. Responsive to the status, a cascade splitting component splits the cascade to remove a dependency relationship of at least one of the fully copy, the incremental copy and the periodic point-in-time copy on the first data. |
