Common Backup and Restore Errors in MySQL
While working with backups and restores in MySQL, you may encounter common errors. Understanding these issues and their solutions ensures smooth recovery and data protection.
- Access Denied Error
This occurs due to an incorrect username or password. Ensure that the MySQL user has the correct privileges for performing backup or restore operations.
- Unknown Database Error
Happens when the target database does not exist before restoring the backup.
Create the database first using:
CREATE DATABASE dbname;
Then proceed with the restore process.
- File Not Found / Cannot Open File
This error occurs when referencing a non-existent .sql file or providing an incorrect file path. Verify the path and ensure the MySQL user has read permissions.
- Permission Denied Error
Happens when either MySQL or the shell user does not have the required permission to write or read the backup file. Run commands with proper permissions or use sudo if necessary.
