Global Options Volume Shadow Copy Service You can specify global options for using the Volume Shadow Copy Service (VSS) These options affect all Writers for VSS backups, but they do not apply to transportable VSS backups. Note: For more information on VSS, see the BrightStor ARCserve Backup Microsoft Volume Shadow Copy Service Guide. On the Volume Shadow Copy Service tab, the File System Backup group box lets you specify how you want BrightStor ARCserve Backup to handle open files during file system backups. These options do not affect Writers and Components. ■ Use VSS--Directs BrightStor ARCserve Backup to use VSS to handle the backup of open files. If this check box is not selected, VSS support is not used and the BrightStor ARCserve Backup Agent for Open Files (if available) is used to handle open files. If the BrightStor ARCserve Backup Agent for Open Files is not available and Use VSS is not selected, a traditional backup is performed. However, the backup will be incomplete if there are any open files that cannot be backed up. ■ Revert to traditional backup if VSS fails--Directs BrightStor ARCserve Backup to execute a traditional backup if an attempt to create a VSS backup fails. If the BrightStor ARCserve Backup Agent for Open Files is available, it is used to handle open files if this option is selected and the VSS backup fails. If this check box is not selected and the VSS backup fails, the backup job fails. The Writers and Components group box lets you specify how you want BrightStor ARCserve Backup to treat Writers and Components. These are global options affect all Writers, except for those with Writer-specific options in place. For more information about setting Writer-specific options, see the BrightStor ARCserve Backup Microsoft Volume Shadow Copy Service Guide. ■ Files included by a writer will be excluded from file system backups- Prevents files that belong to a Component from being backed up by a traditional file system backup. This option offers the following advantages: - Avoids backing up files that have already been backed up by VSS. - By excluding files from traditional backups, fewer files are processed, and traditional backups take less time to complete. - Helps achieve successful backups by eliminating certain problems associated with files that must be processed as a group; for example, files associated with a Writer or database application. In a traditional backup, there is no mechanism to ensure that the files are processed together. ■ Files excluded by a writer will be excluded from file system backups- Prevents files that have been excluded from being backed up by a Component from being backed up by a traditional file system backup.
