Select the volume with insufficient space.On older server operating systems, this may instead be a tab in Properties. To access the utility, right click any volume and choose Configure Shadow Copies. Warning: This is not recommended in a Hyper-V environment. It is possible to change the shadow storage association to use a volume with sufficient free space The location can be changed from the Shadow Copies utility, or from the command line. If it is not clear which volume has insufficient space, see “How to Check Which Volume is Causing the Error”, below. The smallest amount of space that can be allocated is configurable, but Microsoft Support has recommended maintaining at least 42 MB free on the system reserved partition.

For virtual machines, the simplest solution is usually to increase the size of the VM’s hard disk, then expand the volume in Disk Management.Īlthough it is sometimes possible to create a shadow copy using less than 1% of the free space on a volume, 15%-20% free space is often required on busy volumes. If a volume is low on disk space, the solution is to delete files, expand the volume, or redirect shadow copies to another volume. Within the VM guest OS that cannot be backed up or replicated, use the Disk Management utility (diskmgmt.msc) to view free space on each NTFS volume:



When you enlarge C: drive make sure you leave sufficient space in the destination drive for the third partition.Īs you have existing partitions in the destination and I assume you will wish to resize C: drive at step 4. I shall make the assumption you wish to enlarge C: drive so the destination drive is fully used with the 3 partitions.
