When using the "Database Snapshots" option for processing the Blackbaud Data Warehouse ETL available as of 4.0 SP11, the ETL may fail with error:
An OLE DB record is available. Source: "Microsoft SQL Server Native Client 11.0" Hresult: 0x80040E14 Description: "Cannot open database "BBInfinity_SNAPSHOT_FOR_ETL" requested by the login. The login failed.".
Subsequent ETL refresh attempts may also fail with errors such as: ***Snapshot exists or sqlcmd_snapshot_exists command failed.*** or ***sqlcmd_destroy_snapshot command failed.***
