About

Percona XtraBackup is the world's only open-source, free MySQL hot backup software that performs non-blocking backups for InnoDB and XtraDB databases. With Percona XtraBackup, you can achieve the following benefits:

  • Backups that complete quickly and reliably
  • Uninterrupted transaction processing during backups
  • Savings on disk space and network bandwidth
  • Automatic backup verification
  • Higher uptime due to faster restore time

XtraBackup essentially performs rsync-style copying of InnoDB data and transaction log files. After performs the copying several times, it performs an in-place InnoDB crash recovery to build reliable, usable, safe copies of InnoDB. There are also other options to do incremental backups, streaming backups, slave server creation, and more.
