Steps to Reproduce
To prepare the test, create a new database, then create full, diff and log backups of the database, including at least one mirrored copy of each backup, using the MIRROR TO clause of the BACKUP command. T-SQL for these steps not included here. The command below is just the dbatools command to run Test-DbaLastBackup after you've created a database and backups which include at least one mirrored copy.
Test-DbaLastBackup -SqlInstance MyServer\MyInstance -Database MyDatabase -Destination MyServer\MyInstance -NoCheck -Prefix "dbatools-testrestore-MyServer-MyInstance-$databaseName"Please confirm that you are running the most recent version of dbatools
2.1.12
Other details or mentions
I created dbatools bug report #5360 on April 11, 2019. A fix was created via #5361 which seems to work for backup types of FULL and DIFF, but if you include LOG backups in your test restore, you still get the errors.
