MySQL增量备份

Question

我有一个 mysql 服务器，尝试每天备份数据库，仅备份所需的更改，请提供如何在 mysql 上设置增量备份

Answer 1

While Percona Xtrabackup can do the job even for large databases, IMHO it is a bit complex to install and setup.

For small to medium databases a simpler approach uses a combination of mysqldump and rdiff-backup to obtain an incremental mysql backup. Something like this:

#!/bin/bash
mysqldump --single-transaction --quick --skip-extended-insert --routines -umyuser -pmysecret dbname > /path/to/dumps/dir/dbname.dump;
rdiff-backup /path/to/dumps/dir/ /path/to/backup/dir/

On my blog you can read more details on how to perform MySQL incremental backup with mysqldump and rdiff-backup .

Answer 2

There are two tools available in the market which supports the incremental backup 1- Percona Xtra Backup; it is free and easy to use 2 - mysqlbackup, this comes with enterprise MySQL license only.
