Specifying advanced options (Windows DS-Client)
The Specify Advanced Options page contains advanced options that are available for Windows file system backup sets.
• Retain the default settings unless you have a specific, and then click Next.
For details on individual options, see the F1 help. The following is an introduction to the sections that appear on this page.
• Windows 2000 & up options
These additional options are 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.
• 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 can 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 can 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 bare metal restore (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). Unless BMR provisioning is supported by your installed DS-Client, it is recommended that you do not select this option.
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 might want to force the backup of those files by enabling this option.
