    Hi,

    I have seen this problem a couple of times on windows 2003 servers even
    though this is not a common issue (different clients). When I look at shadow
    copies of a drive, I see only 1 copy. It looks like everytime it does a copy,
    it deletes the old ones. I've checked the schedule, the quota,
    deactivate/reactivate with default options, all the options, everything is
    fine and even redoing the shadow copy configuration did nothing. If I do a
    shadow copy manually, I now see 2 shadow copies. The one made by the schedule
    and mine (I've done a couple manually and can see all of them). But at the
    next schedule, I will see only 1 copy which is the last one made
    automatically. The other automatic copy and the manual ones dissapearing.

    I've also checked with the command vssadmin that everything is fine and no
    errors in event viewer. On the server I am having the issue ritght now, I see
    multiple copies for the C: drive but only one for the D: drive (so basically
    don't have the problem for the C: drive). I have configured and used Shadow
    copy a lot over the years and always use default values which is fine with me.

    Any ideas?

    Thanks

  2. AFAIK, the number of copies retained, depend on the available disk
    space....are you running low?

  3. Yes, well that is: not only

    It relies on (if set in registry)

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Settings\MaxShadowC
    opies

    as well as the maxsize which you can specify like this:

    vssadmin resize shadowstorage /for=<vol_letter:>: /on=<vol_letter:>
    /maxsize=XXGB
