IVssBackupComponents::Query returns a value of "0x1" or "S_FALSE"

Summary

When you use the IVssBackupComponents::Query method to query providers on the system and on the completed shadow copies in the system, the query may return a value of 0x1 or S_FALSE.

Note These values are not listed on the IVssBackupComponents::Query method webpage on the Microsoft Developer Network (MSDN) website.

More Information

The IVssBackupComponents::Query method currently returns a list of all available providers and all completed shadow copies. This return value may also mask a failure of a provider that is installed on the system because we query all providers on the system. If the other providers on the system have no snapshots, the Query method may return a value of 0x1 or S_FALSE instead of the expected return value of VSS_E_OBJECT_NOT_FOUND.
