修复方式

Enable physical backup with incremental support in scheduler.xml: <backup increment_flag="1" increment_interval_day="1" mydumper="0" xtrabackup="1" /> Configure the ZK backup retention policy in backupConf.xml: <backup backupfile_save_dir="/data/home/zkback" resv_capacity="800" resv_days="30"> Configure off-site backups (COS/S3/HDFS) for disaster recovery. Test recovery regularly.
