ClickHouse Backup and Restore Strategy with Spring Boot

December 04, 2025

ClickHouse does not have traditional backups but provides snapshot and export methods. You can integrate these into your Spring Boot workflow.

1. Create a Backup Using Snapshots

On ClickHouse server:

BACKUP TABLE users TO Disk('backups', 'users_backup');

This saves a snapshot to the configured storage.

2. Restore from a Backup

RESTORE TABLE users FROM Disk('backups', 'users_backup');

The table is restored into the current database.

3. Export Data to Files

For portability, use clickhouse-client:

clickhouse-client --query="SELECT * FROM users" > users_dump.sql

This file can be versioned and stored safely.

4. Import Data Back

clickhouse-client --query="INSERT INTO users FORMAT CSV" < users_dump.sql

Simple restore using exported data.

5. Automating in Spring Boot

You can trigger backup commands with JDBC:

jdbcTemplate.execute("BACKUP TABLE users TO Disk('backups','users_backup')");

This allows programmatic backups.
