smart copy | (VLS specific term) A copy of the backed up data created from |
| the virtual tape to the physical tape library. The smart copy |
| process allows Data Protector to distinguish between the source |
| and the target medium thus enabling media management. |
| See also Virtual Library System (VLS). |
smart copy pool | (VLS specific term) A pool that defines which destination library |
| slots are available as smart copy targets for a specified source |
| virtual library. |
| See also Virtual Library System (VLS) and smart copy. |
SMBF | The Session Messages Binary Files (SMBF) part of the IDB stores |
| session messages generated during backup, restore, object |
| copy, object consolidation, and media management sessions. |
| One binary file is created per session. The files are grouped by |
| year and month. |
snapshot | (HP StorageWorks VA and HP StorageWorks EVA specific term) |
| A form of replica produced using snapshot creation techniques. |
| A range of snapshot types is available, with different |
| characteristics, depending on the arrays/techniques used. Such |
| replicas are dynamic and may be either virtual copies, still reliant |
| upon the contents of the source volumes, or independent exact |
| duplicates (clones), depending on the snapshot type and the |
| time since creation. |
| See also replica and snapshot creation. |
