IBM Tivoli Storage Manager for UNIX and Linux: Backup-Archive ...

storage agent. A program that enables Tivoli Storage Manager to back up and restore client data directly to andfrom SAN-attached storage.storage area network (SAN). A high-speed communications network optimized for storage.storage pool. A named set of storage volumes used as the destination of backup, archive, or migrated copies.Ttarget node. A client node for which other client nodes (called agent nodes) have been granted proxy authority. Theproxy authority allows the agent nodes to perform operations such as backup and restore on behalf of the targetnode, which owns the data being operated on.TCA. Trusted Communications AgentTCP/IP. Transmission Control Protocol/Internet Protocol.timeout. A time event involving:v An event that happens at the end of a predetermined period of time that began at the happening of anotherspecified event.v A time interval allotted for certain operations to happen. For example, response to polling or addressing beforesystem operation is interrupted and must be restarted.v A terminal feature that logs off a user if an entry is not made within a specified period of time.Tivoli Storage Manager. A client-server licensed program product that provides storage management and dataaccess services to customers in a multivendor computer environment.Transmission Control Protocol/Internet Protocol (TCP/IP). A standard set of communication protocols that supportspeer-to-peer connectivity of functions for both local and wide-area networks.Trusted Communications Agent (TCA). A program that can handle the sign-on password protocol when passwordaccess is generated. The main process (for example, dsmj, dsmc) makes a run time decision based on the passwordaccess option setting, the user ID, and the executables’ access privileges to run this program. The file that containsthis program must have the ’s’ bit set in its mode field and the owner must be root.Vversion. Storage management policy allow back-level copies of backed up objects to be kept at the server wheneveran object is newly backed up. The most recent backed up copy is called the ″active″ version. Earlier copies are″inactive″ versions. The following backup copy group attributes define version criteria: versions data exists, andversions data deleted.virtual file space. A representation of a directory on a network-attached storage (NAS) file system as a path to thatdirectory. A virtual file space is used to back up the directory as a file space in Tivoli Storage Manager server storage.Wwildcard character. An asterisk (*) or question mark (?) character used to represent multiple (*) or single (?)characters when searching for various combinations of characters in alphanumeric and symbolic names.windowed interface. A type of user interface that is either a graphical user interface or a text-based interface. Thetext-based interface maintains a close affinity to the graphical user interface, including action bars and theirassociated pull-down menus and windows. See graphical user interface.workstation. A programmable high-level workstation (usually on a network) with its own processing hardware suchas a high-performance personal computer. In a local area network, a personal computer that acts as a single user orclient. A workstation can also be used as a server.world wide name. A unique 48 or 64 bit number assigned by a recognized naming authority (often via blockassignment to a manufacturer) that identifies a connection or a set of connections to the network. Abbreviated WWN.A WWN is assigned for the life of a connection (device). Most networking technologies (e.g., Ethernet, FDDI, etc.) usea world wide name convention.Glossary 535
