Failed to Execute a DBService Backup Task

Symptom

ls /srv/BigData/LocalBackup/default_20190720222358/ -rlth

Figure 1 Checking the backup file

Cause Analysis

  • Check the backup log of DBService in /var/log/Bigdata/dbservice/scriptlog/backup.log. It is found that the backup is successful but fails to be uploaded to the OMS node.

  • The failure is caused by the SSH failure.

Solution

  1. If the network is faulty, contact network engineers.
  2. Perform backup operations again after the network fault is rectified.
