# Check the backup configuration in scheduler.xml grep -A5 '<backup' /path/to/tdsql/conf/scheduler.xml # Expected: xtrabackup="1" # Check the ZK backup configuration cat /path/to/tdsql/conf/backupConf.xml # Verify the backup directory ls -la /tdsqlbackup/ 2>/dev/null

조치 방법

조치 방식: 가이드 또는 인프라 패치

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.
