Problem
Cross Mount Points and WindowsSolution
Overview:
There is a NetBackup Policy attributecalled Cross mount points. It is documented as: The Crossmount points attribute controls whether NetBackup crosses file system boundariesduring a backup on UNIX clients.
Although not documented as such, thispolicy attribute also applies to Windows 2003 and 2008 OperatingSystems.
Details:
In Windows 2003 and 2008, it is possible toconfigure a mount point in Disk Management. When configuring a NewPartition, instead of assigning the partition to a drive letter, select theoption "Mount in the following empty NTFS folder:" See Example 1below:
Example1:
In thisexample, if a NetBackup Policy is configured with E:\ or ALL_LOCAL_DRIVES in the Backup Selections list, the contents of E:\MyMountPoint will not get backed up if the attribute Cross mountpoints is not selected. This is to prevent circular/infinitebackups.
In order to backup the contents of E:\MyMountPoint, thepath needs to be specifically listed in Backup Selections or Cross mountpoints needs to be selected.
If you are unsure if your operatingsystem has a partition mounted as a mount point as opposed to a drive letter,you can run the command mountvol. Among other things, this commandwill list all the mounted volumes and their mount points.
