Manager attempted to transfer during all command attempts. Therefore, thestatistics for bytes transferred might not match the file statistics, such as those forfile size.Adaptive subfile backupsIf you plan to perform a backup over a network device with limited bandwidth,such as a modem, you can reduce the network traffic by using the subfilebackupoption.If you plan to use this option, ensure that you specify the subfilebackup,subfilecachepath and subfilecachesize options during the initial backup of your file.The options specify whether to perform an adaptive subfile backup along with thepath and size of the data to be transferred.Associate a local snapshot with a server file spaceUse the snapshotroot option with the incremental command in conjunction with avendor-supplied application that provides a snapshot of a logical volume, toassociate the data on the local snapshot with the real file space data that is storedon the Tivoli Storage Manager server.The snapshotroot option does not provide any facilities to take a volume snapshot,only to manage data created by a volume snapshot.LoopThe loop command starts an interactive command-line session that is maintaineduntil you enter quit.If you are required to enter a password, you are prompted for it before the loopmode prompt appears.Note: It is not possible to enter loop mode without a valid server contact. One ofthe consequences is that certain commands, such as restore backupset-location=file, are only accepted on the initial command line when a valid serveris not available.In an interactive command-line session, it is unnecessary to precede each commandname with dsmc and your password, if one is required.In interactive mode, options you enter on the initial command line overrides thevalue that you specified in your client options file (dsm.opt). This value remains ineffect for the entire interactive session unless overridden by a different value on agiven interactive command. For example, if you set the subdir option to yes inyour client options file (dsm.opt), and you specify subdir=no on the initialcommand line, the subdir=no setting remains in effect for the entire interactivesession unless overridden by the subdir=yes value on a given interactive command.However, the subdir=yes value only affects the command it is entered on. Whenthat command completes, the value reverts back to subdir=no, the value at thebeginning of the interactive session.You can enter all valid commands in interactive mode except the schedule andloop commands.Chapter 13.
