MySQL备份工具，支持各种参数选项，使用不同的选项极有可能影响备份处理过程。本文使用我们常规认为合理的备份参数，测试/验证是否存在容易忽视的坑
# 常规备份参数 # mysqldump shell> mysqldump --single-transaction --master-data=2 -B replcrash >dbname_dump_serverid_`date +%Y%m%d`.sql # mysqlpump shell> mysqlpump --single-transaction -B replcrash >dbname_pump_serverid_`date +%Y%m%d`.sql # mydumper shell> mydumper -B replcrash -o /data/backup/mydumper # XtraBackup # backup shell> innobackupex [--defaults-file=MY.CNF] BACKUP-ROOT-DIR # apply-log shell> innobackupex --apply-log [--defaults-file=MY.CNF] BACKUP-DIR # copy-back shell> innobackupex --copy-back [--defaults-file=MY.CNF] BACKUP-DIR
