-#### Partial Validation

-If you have enabled [partial restore](#setting-up-partial-restore) before taking backups, you can validate or exclude from validation the arbitraty number of specific databases using [partial restore options](#partial-restore-options) with the [validate](#validate) command.

-To validate only one or more databases, run the `validate` command with the following options:
-
-    pg_probackup validate -B backup_dir --instance instance_name -i backup_id --db-include=database_name

-The option `--db-include` can be specified multiple times. For example, to validate only databases "db1" and "db2", run the following command:
-
-    pg_probackup validate -B backup_dir --instance instance_name -i backup_id --db-include=db1 --db-include=db2
