Clearing out Orphaned Shadow Copies

Orphaned Shadow Copies

In this article, I go over how to get rid of Orphaned Shadow Copies that do not get cleared out by issuing: vssadmin shadows delete /all

Steps to clear out all orphaned shadow copies

  • vssadmin shadows delete /all
  • vssadmin shadows list
    • verify orphaned shadow copies still exist
  • Use the following command to resize shadow storage, consequently, clears out any shadow copies on that drive
    • vssadmin Resize ShadowStorage /For=C: /On=C: /MaxSize=300MB
      • Note: Repeat this for each drive with orphaned shadow copies
  • Afterward, do a shadows list to verify the shadow copies have been cleared out
    • This process can take a very long time for large drives with a lot of shadow copies.
  • With all that finished, reset your shadow copies to either unbounded or 50-100 GB if you have space.

In the day and age where virtualization has become so prevalent, you shouldn’t need many shadow copies.
