ExamplesCommand line:res i d: -incrementalIncrthresholdThe incrthreshold option specifies the threshold value for the number of directoriesin any journaled file space that might have active objects on the server, but noequivalent object on the workstation.When a Windows client deletes a file or directory with a long name, it sometimesreports this using a compressed name. After the object is deleted, the compressedname might be reused and the deletion notice can no longer identify a uniqueobject. During a journaled incremental backup of a file space, this can result in theno active version response from the server resulting in an unsuccessful expire for anobject.The incrthreshold option allows you to specify what to do when this conditionarises:vvvIf you set the incrthreshold option to 0 (the default), Tivoli Storage Managertakes no action. The primary consequence is that, during a restore of such adirectory, these objects might be inadvertently restored. When the nextnon-journaled incremental is run on this directory, Tivoli Storage Managerexpires all objects in the directory that exist on the server but not on theworkstation.If you specify a value greater than zero, Tivoli Storage Manager saves thedirectory name of an object in the journal during journaled backups. During afull file space journaled incremental backup, if the number of directories in thefile space is greater than or equal to this value, a full incremental backup of eachdirectory occurs. This takes place automatically after completion of the journaledbackup and does not require entry of another command.If you set the incrthreshold option to 1, Tivoli Storage Manager performs a fullincremental backup of these directories whenever a no active version response isreceived during a full file space journaled incremental backup.Supported ClientsThis option is for all Windows clients.Options FilePlace this option in the client options file (dsm.opt). You can set this option on theBackup tab → Threshold for non-journal incremental backup field of thePreferences editor.Syntax►► INCRTHreshold numberdirectories ►◄ParametersnumberdirectoriesSpecifies the threshold value for the number of directories in any journaled filespace that might contain active files that should be expired.
