DHCP Jet Database

To avoid unnecessarily high data change rates and excessive use of network bandwidth, the DHCP jet database backup copy needs to be excluded from the LiveVault Online Backup Service backup.

LiveVault Online Backup Service Agent version 3.3 and later automatically exclude the DHCP jet database backup copy. If you are running an earlier Agent version, you must manually create the exclusion.

The DHCP backup database path is specified in the registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCPServer\Parameters value BackupDatabasePath

However, there is data in that path that must be backed up, so only exclude the backup copy of the jet database by appending \jet\* to the specified path in the BackupDatabasePath value. For example, if the BackupDatabasePath value is %SystemRoot%\System32\dhcp\backup (which is the default) and SystemRoot is C:\Winnt, then append \jet\* to create the following exclusion:

Exclude C:\Winnt\system32\dhcp\backup\jet\* (plus subdirectories)

Important: Do not exclude the entire backup database path, as it contains information that must be backed up.

In the tree view on the Files to Backup tab, you will see the icon for the automatically excluded directory and subdirectories. Parent directories of the automatically excluded directory are marked in MyLiveVault with one of the "partially excluded" icons, either (if a parent directory is selected), or (if a parent directory is not selected).
