The value is the percent of theused space that is expected to change on the volumeon which the snapshot is taken. On a volume withhigh file system write activity, this value can beincreased to remove the condition where the snapshotcache fills up during the operation. The snapshotcache location is specified with thesnapshotcachelocation option. This option is onlyvalid if the LVSA is installed and configured for openfile or online image support.During an online image backup or open file supportoperation, use this option to specify the number ofadditional times the LVSA tries to achieve thesnapshot file system idle wait time before the onlineimage backup or open file support operation fails.This option is only valid if the LVSA is installed andconfigured for open file or online image support.During an online image backup or open file supportoperation, use this option to specify the amount oftime that must pass in which there is no writeactivity (read activity is ignored) on a volume beforea snapshot can be taken. This option is only valid ifthe LVSA is installed and configured for open file oronline image support.Use the snapshotproviderfs option to enablesnapshot-based file backup and archive operations,and to specify a snapshot provider.Use the snapshotproviderimage option to enablesnapshot-based online image backup, and to specify asnapshot provider.Use the snapshotroot option with the incremental,selective, orarchive commands in conjunction with aindependent software vendor application thatprovides a snapshot of a logical volume, to associatethe data on the local snapshot with the real file spacedata that is stored on the Tivoli Storage Managerserver.Specifies whether to include subdirectories of anamed directory.Specifies whether Tivoli Storage Manager usesadaptive subfile backup.Specifies the path where the client cache resides foradaptive subfile backup processing.Specifies the client cache size for adaptive subfilebackup.Specifies whether you want Tivoli Storage Manager towait for a tape mount if it is required for a backup,archive, restore, or retrieve process, or to beprompted for a choice.Chapter 12.
