from a local file system to Tivoli StorageManager storage and replacing the fileswith stub files on the local file system.Contrast with threshold migration anddemand migration.selective recallThe process of copying user-selected filesfrom Tivoli Storage Manager storage to alocal file system. Contrast with transparentrecall.serializationThe process of handling files that aremodified during backup or archiveprocessing. See dynamic serialization, staticserialization, shared static serialization, andshared dynamic serialization.server A software program or a computer thatprovides services to other softwareprograms or other computers.server options fileA file that contains settings that controlvarious server operations. These settingsaffect such things as communications,devices, and performance.server-prompted scheduling modeA client/server communication techniquewhere the server contacts the client nodewhen tasks must be done. Contrast withclient-polling scheduling mode.server storageThe primary, copy, and active-data storagepools that are used by the server to storeuser files such as backup versions, archivecopies, and files migrated from spacemanager client nodes (space-managedfiles). See also active-data pool, primarystorage pool, copy storage pool, storage poolvolume, and volume.sessionA logical or virtual connection betweentwo stations, software programs, ordevices on a network that allows the twoelements to communicate and exchangedata.session resource usageThe amount of wait time, processor time,and space that is used or retrieved duringa client session.shared dynamic serializationA value for serialization that specifies thata file must not be backed up or archivedif it is being modified during theoperation. Tivoli Storage Manager retriesthe backup or archive operation a numberof times; if the file is being modifiedduring each attempt, Tivoli StorageManager will back up or archive the fileon its last try. See also serialization.Contrast with dynamic serialization, sharedstatic serialization, and static serialization.shared libraryA library device that is used by multiplestorage manager servers.shared static serializationA copy-group serialization value thatspecifies that a file must not be modifiedduring a backup or archive operation.Tivoli Storage Manager attempts to retrythe operation a number of times. If thefile is in use during each attempt, the fileis not backed up or archived. See alsoserialization. Contrast with dynamicserialization, shared dynamic serialization,and static serialization.snapshotAn image backup type that consists of apoint-in-time view of a volume.space-managed fileA file that is migrated from a client nodeby the space manager client. The spacemanager client recalls the file to the clientnode on demand.space managementThe process of keeping sufficient freestorage space available on a local filesystem for new data by migrating files toserver storage. Synonymous withhierarchical storage management.space manager clientA program that runs on a UNIX or Linuxsystem to manage free space on the localfile system by migrating files to serverstorage. The program can recall the fileseither automatically or selectively. Alsocalled hierarchical storage management(HSM) client.space monitor daemonA daemon that checks space usage on allfile systems for which space managementis active, and automatically startsthreshold migration when space usage ona file system equals or exceeds its highthreshold.Glossary 689
