The boot disk was backed up even though it was excluded from the backup.

The virtual machine only has a boot disk and no other disks.

The boot disk is part of a managed volume (Windows LDM or Linux LVM). NetBackup can only exclude a boot disk if it is fully contained on a single disk.

The virtual machine's boot disk is an independent disk and has no other disks.

NetBackup was not able to identify the boot disk. The boot disk must include the boot partition and the system or the boot directory.

A restored boot disk has no data.

The boot disk is an independent disk. NetBackup cannot back up the data in this type of disk.

A restored virtual machine has a disk that contains missing or incomplete data.

The disk that has missing or incomplete data was excluded from the backup.

A data disk (or disks) was backed up even though it was excluded from the backup.

The virtual machine has only one disk (such as C:). In this case, the single drive is backed up and is not excluded.

A virtual machine is restored to an unexpected state.

You added a disk to the virtual machine and changed the settings that exclude disks. However, you did not create a backup of the entire virtual machine after you made the change.

Not all files can be restored individually.

If you remove disks from the custom attribute value between the differential backups, only those files that changed since the last backup can be restored individually. Alternatively, you can restore the entire virtual disk or the VM. After the next full backup, you can restore any of the files individually.

If you remove controllers from Specific disks to be excluded between the differential backups, only those files that changed since the last backup are available for restore. All files are available for restore after the next full backup.
