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 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 Arcserve Backup to handle open files during file system backups. These options do not affect Writers and Components.
If this check box is not selected, VSS support is not used and the Arcserve Backup Agent for Open Files (if available) is used to handle open files. If the 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.
Note: This option requires you to install and license the Arcserve Backup Agent for Open Files on the source computer.
Be aware of the following behavior:
The Writers and Components group box lets you specify how you want Arcserve Backup to treat Writers and Components. These global options affect all Writers, except for those with Writer-specific options in place. For more information about setting Writer-specific options, see the Microsoft Volume Shadow Copy Service Guide.
There may be files associated with an application that should never be backed up (for example, the Windows page file). Each Writer is aware of whether its associated application maintains any such files. Selecting this option allows Arcserve Backup to use this information when performing traditional backups.
Selecting this option ensures that any backup is consistent and that all of the files associated with a Writer are backed up before the backup is considered successful, regardless of how many components are associated with the Writer.
