Introducing Xtrabackup Manager
2 likes2,243 views
This document introduces XtraBackup Manager, a command line tool written in PHP5 that leverages cron, netcat and ssh to automate MySQL backups across Linux and Solaris servers. It works by installing XtraBackup on backup and database servers, then using XtraBackup Manager to schedule and run full or incremental backups to designated storage volumes. Key features include throttling, email alerts, logging and materialized backups to reduce restore times, with the goal of providing an open source alternative to proprietary backup solutions.

- 22. A few little facts... • XBM for short (cmd line tool) • Written in PHP5 (Object Oriented) • Leverages cron, netcat and ssh • Works on Linux and Solaris • GPLv2
- 23. So how does it work?...
- 24. QuickStart Guide http://code.google.com/p/xtrabackup-manager/wiki/QuickStartGuide
- 25. What you’ll need... • Server with plenty of storage space (management server) – MySQL 5.x+ – PHP 5.1.6+ (CLI) • mysql or root access to the servers • XtraBackup 1.6.4+
- 26. Installing... • Create UNIX user for XBM • Create MySQL user for XBM + Schema • Download latest tarball • Extract to xbm user homedir • Initialize the XBM schema: mysql xbm < ./sql/schema_init.sql
- 27. Setup SSH Trust... XBM user must be able to SSH without password: shell> ssh mysql@dbhost
- 28. Install XtraBackup... • Download & Install XtraBackup 1.6.4+ • Install on both backup server and DB hosts • Ensure XtraBackup is in $PATH too
- 30. ./xbm ./xbm backup list ./xbm volume add "mybackupdir" /home/xbm/backups/ ./xbm volume list ./xbm host add localhost Just-testing ./xbm host list ./xbm backup add localhost monthlyBackup FULLONLY "30 03 01 * *" mybackupdir /var/lib/mysql root root ./xbm backup list ./xbm backup run localhost monthlyBackup ./xbm snapshot list localhost ls ../backups/ ls ../backups/localhost ls ../backups/localhost/*
- 32. Backup Strategies? • When do I take full backups? • When should I take incremental backups? • How many snapshots do I keep? • ... etc.
- 33. Backup Strategies! • Full Only • Continuous Incrementals • Rotating Sets of Incrementals
- 40. How about time to restore?
- 41. Enter Materialized Backups...
- 42. Materialized backups mean less waiting...
- 44. Other neat features?... • Throttling • Email Alerts • Rich logging • Immediate Apply Logs • Did I mention 100% open source
- 45. What is it missing?
- 46. What is missing? • 1.0 release • pitr (copy binlogs) • compression • encryption • progress indicator • GUI
- 47. Meh... Any alternatives? • Zmanda Recovery Manager (ZRM) • Used to be open source in 2006 • Still there, does support xtrabackup (and everything else) • GUI, a bell and 3 whistles included!
- 48. Try it out! Google Code: http://code.google.com/p/xtrabackup- manager MySQL Soapbox - (My Blog) http://mysqlsoapbox.blogspot.com
- 49. Thank you!
