SolusVM 2 VM backup fails with the error:

SVM_ERROR: cannot backup the virtual server "d753e261-5a73-45e4-aa6d-4042fd29b85d": back up disk "sda" with path "/dev/solusvm/433_0": upload failed, backup is corrupted: context deadline exceeded

Cause

Slow network speed between Compute Resource and Backup Node

Resolution

Contact DC to increase the bandwidth rate to the Backup Node.

Alternatively,

  1. Connect to Compute Resource where the affected VM is hosted via SSH
  2. Adjust the below line in the config file /etc/solus/agent.json:

    CONFIG_TEXT: "backup_create_timeout_hours": 0,

    to:

    CONFIG_TEXT: "backup_create_timeout_hours": 6,

    Default value is 4 hours. Increase the value even more if necessary

  3. Save changes and exit the config file.
  4. Restart solus-agent service:

    # systemctl restart solus-agent
