– Tables, indexes, constraints, views, triggers, routines, privileges
etc.
§ Also contains various extensions within MySQL
– Many of these are runtime metadata
– Processlist, system / status variables, InnoDB runtime data
§ System Views (not real views, not real tables, generated on the fly)

§ Warm Backup (Locking, Logical)
– mysqldump
§ Standby Copy (Hot swappable)
– MySQL Replication
§ Hot Backup (Online, Physical)
– MySQL Enterprise Backup, mysqlbackup

MySQL Backup Tools – Warm Backup
§ Advantages for mysqldump
– Good for small databases / tables
– Logical, so more flexible and portable
§ Disadvantages for mysqldump
– Single thread for dump and restore, slow for larger instances
– Not online, requires a transaction (for InnoDB) or global lock
(for all other non-transactional tables)
– Not incremental (needs binary logs as well, complex recovery)

24. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. Insert Information Protection Policy Classification from Slide 12 of the corporate presentation template24
MySQL Backup Tools – Hot Standby
§ Advantages for MySQL Replication
– Rolling snapshot
– Very quick failover
– Standby can be used for other backup types
§ Disadvantages for MySQL Replication
– Only latest point in time (can use delayed replication with 5.6)
– Not incremental (needs binary logs as well, complex recovery)
– Can't archive (offsite, though can have an offsite standby)

25. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. Insert Information Protection Policy Classification from Slide 12 of the corporate presentation template25
MySQL Backup Tools – Hot Backup
§ Advantages for MySQL Enterprise Backup
– Physical Backup, so very quick (especially restore)
– Ties in natively with Oracle Secure Backup to Tape (SBT)
– Multi-Thread for Performance
– Incremental Backups available
– Compression Built-In
§ Disadvantages for MySQL Enterprise Backup
– No logical option (good to have a periodic mysqldump too)
