| deployed between sites kilometers apart. Fibre Channel connects |
| nodes using three physical topologies: |
| switched. |
Fibre Channel | A Fibre Channel bridge or multiplexer provides the ability to |
bridge | migrate existing parallel SCSI devices, like RAID arrays, solid |
| state disks (SSD), and tape libraries to a Fibre Channel |
| environment. On one side of the bridge or multiplexer there is |
| a Fibre Channel interface while on the other side there are |
| parallel SCSI ports. The bridge or multiplexer enables SCSI |
| packets to be moved between the Fibre Channel and parallel |
| SCSI devices. |
file depot | A file containing the data from a backup to a file library device. |
file jukebox device | A device residing on disk consisting of multiple slots used to |
| store file media. |
file library device | A device which resides on a disk emulating a library with several |
| media, hence containing multiple files, referred to as file depots. |
File Replication | A Windows service that replicates the domain controller store |
Service (FRS) | logon scripts and group policies. FRS also enables replication |
| of Distributed File System (DFS) shares between systems and |
| allows any server to perform replication activity. |
file tree walk | (Windows specific term) The process of traversing a filesystem |
| to determine which objects have been created, modified, or |
| deleted. |
file version | The same file can be backed up multiple times in case of full |
| backups and incremental backups (if the file changed). If the |
| log level ALL is selected for backup, Data Protector retains one |
| entry in the IDB for the filename itself and one for each version |
| (date/time) of the file. |
filesystem | The organization of files on a hard disk. A filesystem is backed |
| up so that the file attributes and the file contents are stored on |
| the backup media. |
(HP StorageWorks Disk Array XP specific term) HP StorageWorks | |
| Disk Array XP allows up to three mirror copies of a primary |
| volume and each of these copies can have additional two |
| copies. The three mirror copies are called |
