Specifying advanced options (Windows DS-Client)
Additional advanced options are available for Windows File system backup sets in the Specify Advanced Options screen.
• Retain the default settings unless there are specific requirements for backup set options, and click Next.
For details on individual options, see the online help for the screen. The following is an introduction to various sections.
• Windows options
Additional options specific to Windows file systems.
• Volume Shadow Copy
This option is available if the target backup computer supports this feature. When selected, DS-Client will use Volume Shadow Copy Service (VSS) to copy the volume(s) selected for backup, then perform the backup of items from that VSS copy. If the VSS copy fails, DS-Client attempts to backup like a normal
File system backup set. For more detailed instructions, see
“Backup using Microsoft VSS (Volume Shadow Copies)”.
• Pure file data backup options
This option controls the automatic file filtering performed by DS-Client during Windows file system backups. By default, Windows DS-Client will exclude some files automatically out of the share-based backup of files, even if such files would be readable (e.g. when using VSS). The excluded files may include:
• temporary files (e.g. pagefile.sys)
• files that are being backed up as part of “System State” backups (e.g. operating system DLLs, executable)
• Registry hive files
• Other files that may interfere with a successful Agentless BMR
Use this option only if there are specific reasons why excluded data would need to be included in the share-based backup.
Selecting this option will interfere with the ability to perform Agentless BMR without manual file filtering, however it can be used in conjunction with the VSS option to allow bootable-disk BMR (this requires 3rd-party BMR provisioning integration). It is recommended that unless BMR provisioning is supported by your installed DS-Client, you should leave this option unchecked.
NOTE: This option normally requires the Volume Shadow Copy option to be selected.
• Backup strategy for backed up files
By default, DS-Client skips files that have already been backed up. It uses each backed up file’s “last modified” time and size for comparison purposes, and if those on the source match those of the latest generation in the DS-Client database, the file will be skipped. Normally this is the required behavior for backup sets. However, in some specific situations, you may want to force the backup of those files by enabling this option.
