You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: backup_restore.go
    path of file: ./repos/wal-g/cmd/sqlserver
    
    the code of the file until where you have to start completion: package sqlserver

import (
	"github.com/spf13/cobra"
	"github.com/wal-g/wal-g/internal"
	"github.com/wal-g/wal-g/i
    
func init() {
	backupRestoreCmd.PersistentFlags().StringSliceVarP(&restoreDatabases, "databases", "d", []string{},
		"List of databases to restore. All non-system databases from backup as default")
	backupRestoreCmd.PersistentFlags().StringSliceVarP(&restoreFrom, "from", "f", []string{},
		"List of source database to restore from. By default it's the same as list of database, "+
			"those every database is restored from self backup")
	backupRestoreCmd.PersistentFlags().BoolVarP(&restoreNoRecovery, "no-recovery", "n", false,
		"Restore with NO_RECOVERY option")
	cmd.AddCommand(backupRestoreCmd)
}
