To perform backup and restore operations for SQL databases in Go, you can use the database/sql
package along with the appropriate driver for your database (e.g., github.com/lib/pq
for PostgreSQL).
Here's an example of how to perform backup and restore operations for a PostgreSQL database:
go get github.com/lib/pq
import (
"database/sql"
"fmt"
"log"
_ "github.com/lib/pq"
)
db, err := sql.Open("postgres", "user=your_user password=your_password dbname=your_db sslmode=disable")
if err != nil {
log.Fatal(err)
}
defer db.Close()
backupPath := "/path/to/backup.sql"
backupCmd := fmt.Sprintf("pg_dump -U %s -h %s -p %s -Fc %s > %s",
"your_user", "your_host", "your_port", "your_db", backupPath)
if err := exec.Command("bash", "-c", backupCmd).Run(); err != nil {
log.Fatal(err)
}
restorePath := "/path/to/backup.sql"
restoreCmd := fmt.Sprintf("pg_restore -U %s -h %s -p %s -d %s -Fc %s",
"your_user", "your_host", "your_port", "your_db", restorePath)
if err := exec.Command("bash", "-c", restoreCmd).Run(); err != nil {
log.Fatal(err)
}
Note that these are just examples for PostgreSQL. For other databases, you'll need to use the specific commands or APIs provided by the respective database.
Also, make sure to handle errors appropriately and adjust the connection parameters and backup/restore commands according to your specific setup.
