Subsequent changes tothe file system are not included in the archive. You can set the snapshotproviderfsparameter of the include.fs option to none to specify which drives do not use openfile support.To control an open file support operation with LVSA, you can specify theseadditional options in your dsm.opt file or as values of the include.fs option:snapshotcachelocation, snapshotcachesize, snapshotfsidleretries, snapshotfsidlewait,snapshotproviderfs, presnapshotcmd, postsnapshotcmd.Note:1. You can use the include.fs option to set snapshot options on a per file systembasis.2. Open file support is only available for local fixed volumes (mounted to eitherdrive letters or volume mount points) formatted with FAT, FAT32 or NTFS filesystems. This support includes SAN-attached volumes that meet theserequirements.3. If the client is unable to create a snapshot, failover to non-OFS backup occurs;the same backup support that would be done if the OFS feature was notinstalled.4. To enable open file support in a cluster environment all workstations in thecluster should have the OFS feature configured.5. When using the open file support feature with either VSS or LVSA, the clientadds the snapshot volume name to the path of the objects being processed. Thesnapshot volume name can be up to 1024 bytes. The complete path (snapshotvolume name plus object path) can be 8192 bytes or less.For information about Tivoli Storage Manager Open File Support restrictions andissues, search for the TSM Client v5.2 Open File Support document under theStorage Management product category at the following Web site:http://www.ibm.com/support/Related conceptsChapter 12, “Processing options,” on page 273Related tasks“Configuring Open File Support” on page 63Archiving data using the GUIYou can archive specific files or entire directories from a directory tree.
