customer's ProtecTIER server. The ProtecTIER Replication Manager
manages the configuration of multiple replication grids in an organization.
An agent on every node in each ProtecTIER server interacts with the server
and maintains a table of its grid members.
replication grid ID
A number from 0 to 63 that identifies a replication grid within an
organization.
replication grid member
A repository that is a member in a replication grid.
replication pairs
Two repositories within a replication grid that replicate from one to
another.
replication policy
A policy made up of rules that define a set of objects (for example, VTL
cartridges) from a source repository to be replicated to a target repository.
repository unique ID (RID)
A number that uniquely identifies the repository. The RID is created from
the replication grid ID and the repository internal ID in the grid.
replication timeframe
A scheduled period of time for replication to take place for all policies.
shelf A container of VTL cartridges within a ProtecTIER repository.
virtual tape library (VTL)
The ProtecTIER virtual tape library (VTL) service emulates traditional tape
libraries. By emulating tape libraries, ProtecTIER VTL enables you to
transition to disk backup without having to replace your entire backup
environment. Your existing backup application can access virtual robots to
move virtual cartridges between virtual slots and drives. The backup
application perceives that the data is being stored on cartridges while
ProtecTIER actually stores data on a deduplicated disk repository.
visibility switching
The automated process that transfers the visibility of a VTL cartridge from
its master to its replica and vice versa. The visibility switching process is
triggered by moving a cartridge to the source library Import/Export (I/E)
slot. The cartridge will then disappear from the I/E slot and appear at the
destination library's I/E slot. To move the cartridge back to the source
library, the cartridge must be ejected to the shelf from the destination
library. The cartridge will then disappear from the destination library and
reappear at the source I/E slot.
