## What it is
Percona XtraBackup is an open-source hot backup utility for MySQL-based servers that performs non-blocking backups of InnoDB, XtraDB, MyISAM, and MyRocks tables. It is designed for production environments, allowing backups of 24x7 loaded servers without locking the database or disrupting performance.

## Use cases
- take hot backups of a mysql database without downtime
- back up innodb tables on a busy production server
- create physical backups of percona server for mysql
- back up mysql 8.0 databases while they stay online
- restore a mysql database from a physical backup
- set up automated nightly backups for a mysql cluster

## When to choose
- you need non-blocking physical backups of MySQL/InnoDB databases
- you run Percona Server or Percona XtraDB Cluster and need compatible backups
- you back up large, heavily loaded 24x7 databases where logical dumps are too slow
- you want an open-source alternative to MySQL Enterprise Backup

## When to avoid
- you need logical, portable backups in SQL format (use mysqldump or mydumper)
- you run MariaDB, which requires its own fork (mariabackup)
- you only back up small, low-traffic databases where simple dumps suffice
- you need cross-engine backups of non-transactional tables without locking considerations
