I have a question on enabling the shadow copy services on a server. Is there any issue if we enabled shadow copy services?

    I cannot see any issue of enabling this as long as you have enough space on the drive that you are enabling this for.

    Depends on your system, but the benefits ALMOST CERTAINLY outweigh the drawbacks.

    1. you need space for the copies
    2. when a copy takes place, the disk will be intensely used for a few seconds.  If you have the server serving data that must flow consistently with no slowdowns this could create a problem.  

    In general, most servers don't even notice the few seconds of "slowness" as the copies are created because most servers are serving up things like word and excel files - small files that are easily retrieved even under a disk load.

    I would recommend storing the copies on a separate physical disk (non-RAID is fine for most people) so that overall performance hits are not as bad as they are by default.
