Answer 1

To solve Restore-spsite: The operation that you are attempting to perform cannot be completed successfully

Try the following solutions:

• Check if the content database has not reached its maximum capacity.
• Create a new content database and restore your backup to the specific content database.

`Restore-SpSite “http://mysitecollectionURL/” -Path "D:\pathname\Backup.bak" -Force -DatabaseServer <SQL server name> - 
  DatabaseName <DB>`

• If the restored site collection is already existed use -force parameter to force the restore and overwrite the database.

• If you want to delete and restore the site collection, make sure you deleted with the "Remove-SPDeletedSite" cmdlet.
