Volume Shadow Copy Services fails, reporting error number 800xxxxx.

There are several causes for Volume Shadow Copy Services failure. They are listed in order of probability:

  • Low disk space on a drive with Volume Shadow Copies Services enabled.
  • The disk is highly fragmented.
  • SQL Server 2000 is installed and one or more databases have a recovery model that is not set to Simple. Windows Small Business Server 2003 Backup can back up a database only if its recovery model is set to Simple.
  • An Event Log is larger than 64 megabytes (MB).
  • Directory Service Access auditing is enabled.

Use the information in the following sections to determine which of these issues is causing Volume Shadow Copy Services to fail and to correct the failure.
