dsmc incremental \\florence\c$\snapshots\snapshot.0However, you might want to associate the snapshot data with the data alreadyprocessed for the c: drive (\\florence\c$). Using the snapshotroot option, youcan associate the data with the file space corresponding to the c: drive(\\florence\c$) on the Tivoli Storage Manager server:dsmc incr c: -snapshotroot=\\florence\c$\snapshots\snapshot.0-ordsmcincr \\florence\c$ -snapshotroot=\\florence\c$\snapshots\snapshot.0On a subsequent day, you can back up a snapshot that was written to an alternatelocation, but managed under the same file space on the server:dsmc incr c: -snapshotroot=\\florence\c$\snapshots\snapshot.1You can perform incremental backups, selective backups, or archives of a singledirectory, directory structure, or single file using the snapshotroot option. In allinstances, the snapshotroot option must identify the root of the logical volume thatwas created by the snapshot. For example:dsmc incr c:\dir1\* -subdir=yes -snapshotroot=\\florence\c$\snapshots\snapshot.1dsmc sel c:\dir1\sub1\file.txt -snapshotroot=\\florence\c$\snapshots\snapshot.1dsmc archive c:\mydocs\*.doc -snapshotroot=\\florence\c$\snapshots\snapshot.1If you want to include or exclude specific file specifications, the include andexclude statements should contain the name of the file system that was the sourceof the snapshot (the c: drive), and not the name of the target of the snapshot(\\florence\c$\snapshots\snapshot.1). This allows you to preserve a set ofinclude and exclude statements regardless of the name of the logical volume towhich the snapshot is written. The following are examples of include and excludestatements.include c:\dir1\.../*.txt lyrmgmtclassexclude \\florence\c$\mydocs\*.docThe following include-exclude statements are not valid because they contain thename of the snapshot:include \\florence\c$\snapshots\snapshot.1\dir1\...\*.txt 1yrmgmtclassexclude \\florence\c$\mydocs\*.docYou must use the snapshotroot option in conjunction with a single file specificationfor a incremental, selective, or archive operation. You cannot specify multiple filespecifications or no file specifications. For example, these commands are valid:dsmc incr c: -snapshotroot=\\florence\c$\snapshots\snapshot.0dsmc incr c:\dir1\* -snapshotroot=\\florence\c$\snapshots\snapshot.0The following command is invalid because it contains two file specifications:dsmc incr c:\dir1\* e:\dir1\* -snapshotroot=\\florence\c$\snapshots\snapshot.0The following command is invalid because it contains no file specification:dsmc incr -snapshotroot=\\florence\c$\snapshots\snapshot.0Note:476 IBM Tivoli Storage Manager for Windows Backup-Archive Clients: Installation and User's Guide
