Bro, combining snapshots and logs, incremental backups are just log backups.

Dumpling

TiDB comes with Dumpling for logical backups and BR for physical backups. When using BR for backups, enabling log backups allows for incremental backups. However, there is a time difference of 1 to 3 minutes between the incremental backups and the database, so it cannot guarantee that all data will be recovered if the database crashes.

BR is used more often and backups are faster. If you need to back up a specific database, use Dumpling.

Perform a full backup using BR.

BR works well.

The managed data has not been officially activated yet, mainly consisting of some configuration data. The data volume is not very large, and BR is used for backup.

Use BR

Cold backup uses BR, hot backup uses TiCDC.

Personally, I think using TiCDC to synchronize to a downstream TiDB cluster is the most perfect backup solution.

Physical backup br + log backup
If the data volume is not particularly large, or for some important tables, daily logical backup with dumpling can also be considered.

No backups, it’s been running for three years.

  1. Full Backup: Full backup is the most common and simplest backup method, achieved by completely backing up the entire database’s data to another storage location. Tools such as mysqldump, TiDB Lightning, or third-party backup tools can be used for full backups.
  2. Incremental Backup: Incremental backup only backs up the data changes that have occurred since the last full backup. In TiDB, Binlog can be used to achieve incremental backups. TiDB’s Binlog records all DML (Data Manipulation Language) operations, including inserts, updates, and deletes. By parsing the Binlog, data changes after a specific point in time can be restored. Common tools include TiDB Binlog, TiDB Pump, and third-party backup tools.
  3. Distributed Backup: For large-scale datasets, distributed backup tools can be considered to improve backup efficiency. For example, TiDB Operator can be used in conjunction with the BR (BR: Backup & Restore) tool running on Kubernetes for distributed backups.

The latest version of Binlog is gradually being phased out of support.

BR performs a full backup.
