Client nodes canrestore, retrieve, or delete their file spacesfrom server storage. In server storage,files belonging to a single file space arenot necessarily stored together.file space ID (FSID)A unique numeric identifier that theserver assigns to a file space when it isstored in server storage.file stateThe space management mode of a filethat resides in a file system to whichspace management has been added. A filecan be in one of three states: resident,premigrated, or migrated. See also residentfile, premigrated file, and migrated file.file system migrator (FSM)A kernel extension that intercepts all filesystem operations and provides any spacemanagement support that is required. Ifno space management support isrequired, the operation is passed to theoperating system, which performs itsnormal functions. The file systemmigrator is mounted over a file systemwhen space management is added to thefile system.file system stateThe storage management mode of a filesystem that resides on a workstation onwhich the hierarchical storagemanagement (HSM) client is installed. Afile system can be in one of these states:native, active, inactive, or global inactive.frequencyA copy group attribute that specifies theminimum interval, in days, betweenincremental backups.FSID See file space ID.FSM See file system migrator.full backupThe process of backing up the entireserver database. A full backup begins anew database backup series. See alsodatabase backup series and incrementalbackup. Contrast with database snapshot.fuzzy backupA backup version of a file that might notaccurately reflect what is currently in thefile because the file was backed up at thesame time as it was being modified.fuzzy copyA backup version or archive copy of a filethat might not accurately reflect theoriginal contents of the file because it wasbacked up or archived the file while thefile was being modified. See also backupversion and archive copy.GGeneral Parallel File SystemA high-performance shared-disk filesystem that can provide data access fromnodes in a cluster environment.gigabyte (GB)In decimal notation, 1 073 741 824 whenreferring to memory capacity; in all othercases, it is defined as 1 000 000 000.global inactive stateThe state of all file systems to which680 IBM Tivoli Storage Manager for Windows Backup-Archive Clients: Installation and User's Guide
