Removable Storage Management

Database (Windows specific term)

A Windows service used for managing removable media (such as tapes and disks) and storage devices (libraries). Removable Storage allows applications to access and share the same media resources.

reparse point (Windows specific term)

Asystem-controlled attribute that can be associated with any directory or file. The value of a reparse attribute can have user-controlled data. The format of the data is understood by the application that stored the data and a filesystem filter that was installed to interpret the data and process such files. Whenever the filesystem encounters a file with a reparse point, it attempts to find the filesystem filter associated with the data format.

replica unit (ZDB specific term)

A logical unit that is used as a target for data replication using snapshot or split mirror technologies. Depending on the vendor and technology used, a replica unit denotes S-VOL on HP StorageWorks Disk Array XP, child (BC) LUN on HP StorageWorks Virtual Array, logical drive on HP StorageWorks Modular SAN Array

replica storage pool (ZDB specific

term)

A number or group of replica storage versions produced during ZDB sessions to be used for the purpose of replica storage rotation, instant recovery, and split mirror restore. The replica storage versions in the replica storage pool are all created using the same backup specification. The size of a replica storage pool is defined for each backup specification as the maximum number
