How Can I Securely Backup and Restore Individual Tables in MySQL?

Securing Single Table Backups in MySQL

When managing substantial databases, it's often necessary to backup specific tables rather than the entire database. MySQL's mysqldump utility offers a flexible backup solution, allowing you to retrieve data from individual tables.

Dumping a Single Table

To dump the data from a single table named 'table_name' in the database 'db_name':

mysqldump db_name table_name > table_name.sql
Copy after login

Alternatively, if the database resides on a remote server, use:

mysqldump -u <db_username> -h <db_host> -p db_name table_name > table_name.sql
Copy after login

Restoring the Table

To restore the backed-up table, follow these steps:

mysql -u <user_name> -p db_name
mysql> source <full_path>/table_name.sql
Copy after login

Or, in a single line:

mysql -u username -p db_name < /path/to/table_name.sql
Copy after login

Compressed Backup Formats

For more efficient backup storage, you can utilize compressed formats.

Dump with Compression:

mysqldump db_name table_name | gzip > table_name.sql.gz
Copy after login

Restore from Compressed Backup:

gunzip < table_name.sql.gz | mysql -u username -p db_name
Copy after login
