Possible Cause

Solution

The upload speed of eBackup VMs is low (< 50 MB/s). This results in OBS response timeout when data is uploaded using the default configuration. "Write data to backup storage failed" is displayed.

For detailed handling measures, see Upload Speed of eBackup VMs Is Too Low.

The configured domain name cannot be resolved when eBackup accesses the VM, resulting in snapshot creation failure.

In the hosts file of eBackup, configure a domain name of the vCenter VM that can be resolved.

Upload Speed of eBackup VMs Is Too Low

  1. Log in to an eBackup VM as the hcp user and switch to the root user.
  2. Run the following command to edit the hcpconf.ini file: 

     vim /opt/huawei-data-protection/ebackup/microservice/ebk_vmware/conf/hcpconf.ini

  3. Press i to enter insert mode and change the parameter values. Change the values of ProductStorageMemoryPoolBlockNum and CommonTaskUsingMaxThread4Backup to 2.
  4. Run the :wq! command to save and exit the file.
  5. Run the cd /opt/huawei-data-protection/ebackup/microservice/ebk_vmware/script command to go to the script directory.
  6. Run the sh ebackup_stop.sh command. Figure 2 shows the command output.

  7. Run the sh ebackup_start.sh command. Figure 3 shows the command output.
