Web Deployment Deployment Error "You cannot back up or restore multiple databases in a single synchronization"

Question

I lost it, especially after following the guide on how to set it up.

Here's how webdeploy is configured in the iis host configuration:

<wdeploy> <backup turnedOn="true" enabled="true" numberOfBackups="4" backupPath="C:\inetpub\Backups\{siteName}" continueSyncOnBackupFailure="false"> <excludedProviders> <provider name="dbMySql" /> <provider name="dbFullSql" /> </excludedProviders> </backup> </wdeploy> 

According to the documentation:

What the backup contains ( documentation )

"... You can change this default behavior by changing the ExcludedProviders backup option or by specifying skipping rules before publishing."

Web Deployment Providers ( Documentation )

"DbFullSql Web Deployment Provider" The dbFullSql provider first publishes databases from a local SQL Server database for a remote SQL Server database.

When I move on to deployment, I get the following message:

Error: BACKUP_FAILED - Skipping backup because it failed due to an unknown reason. For more information, contact your server administrator. Error: You cannot create or restore a backup of multiple databases in a single sync. Error count: 1.

My questions / concerns are why the backup is trying to back up several databases and why it will even be an attempt to backup the databases when the provider was excluded from the configuration.

Help!
