  • Yes, but it may also cause issue. See:

    Shadow copies may be lost when you defragment a volume

    Microsoft recommends that you use a 16-KB or larger cluster allocation unit size when you format the volume if you plan to defragment volumes that are used for shadow copies of shared folders
