Is there a way to backup or restore a specific schema or table on a Cloud SQL server? Backing up the entire set of data, but then being able to restore only certain schemas or tables would be very helpful for multi-tenant systems.

The Cloud SQL use MySQL database with some limitations. You can check out the unsupported features and functions at the following link:

With this in mind any backup/restore tool that are being used for MySQL should work for Google Cloud SQL as well. Using mysqldump for import/export of Cloud SQL is covered at this document:
https://cloud.google.com/sql/docs/import-export
You can use mysqldump to backup specific table or backup entire database and restore only specific tables using the solutions offered in these links:

回答2:
Not via backup/restore. You can export a specific schema or table to Google Cloud Storage, but that's probably not what you're looking for.
回答3:
You can restore the backup to a different instance and then replace the data on the original instance with the data from the backup instance.
