- Common backup methods include using mysqldump to dump databases into SQL files, copying table files, making delimited text file backups, and enabling binary logging for incremental backups by replaying log files.
- Backups should be stored in multiple locations including on separate disks, servers, or cloud storage. A backup strategy includes performing full and incremental backups on a schedule as well as before and after structural changes.

- 8. 8 Why we need backups for ? • Slave provisioning • Build Staging / Dev environments • Disaster recovery - Data Corruption - Malicious SQL - Software Bugs - Hardware failure
- 9. 9 Replication as backup ? Yes • Master crashes • Database physical file corruption • Any physical hardware failure - CPU - RAM - Disk - Network card
- 10. 10 Replication as backup ? No • Application Bug • Database Hack • Malicious SQL commands
- 11. Types of backups
- 12. 12 Types of backups - Logical • Structure and data are saved as logical structure • CREATE DATABASE / TABLE • INSERT INTO • Can easily be used for selective restore (Only one database/table) • Good when physical file is fragmented / corrupted • Taken while MySQL is running • Slower than physical • Tools: mysqldump, mydumper, mysqlpump
- 13. 13 Types of backups - Physical • Raw copy of your databases and tables • Can be used for selective restore (Only one database/table) • Fast for either Dump and restore • Can be taken while MySQL is running • Bad for table corruption • Tools: Percona XtraBackup, MySQL Enterprise Backup, snapshots, rsync, cp
- 14. 14 Types of backups - Differential or Incremental • Differential - Full copy of the database - Each differential backup has all the changes since last full backup • Monday: FULL • Tuesday: Incremental since Monday • Wednesday: Incremental since Monday • Thursday: Incremental since Monday
- 15. 15 Types of backups - Differential or Incremental • Incremental - Full copy of the database - Each incremental backup has all the changes since last backup • Monday: FULL • Tuesday: Incremental since Monday • Wednesday: Incremental since Tuesday • Thursday: Incremental since Wednesday

- 20. 20 Encryption • Encrypt - xtrabackup --backup --encrypt=AES256 --encrypt-key-file=/data/backups/keyfile --target-dir=/data/backups • --encrypt-threads (used with --parallel ) • Decrypt - xtrabackup --decrypt=AES256 --encrypt-key-file=/data/backups/keyfile --target-dir=/data/backups
- 21. Compression
