  1. Advanced Configuration

Serial Upload per Instance during Snapshot

The following steps depict configuring the Trilio for OpenStack to override the default snapshot upload functionality.

By default, during a snapshot, Trilio will consider all the instances that are members of a workload and starts uploading the resources of each instance simulateously. In some cases, it may be required that the snapshots must be done in serial per VM such that backup of all the disks of one VM/instance must be finished before taking backup of the other VMs that are part of that workload.

Trilio has a provision to update the default behaviour of considering all the instances of a workload during backup process, by introducing a configrable parameter in the on of its services.

Follow the below mentioned steps to set the serial upload as the default behavior.

Finding the required configuration file

As per the OpenStack distribution, look for the configuration file of workloadmgr-api(wlm-api) and workloadmgr-workloads(wlm-workloads) services or containers on the controller plane.

The default location of this configration file in the container or VM where it is running is /etc/triliovault/triliovault-wlm.conf

Once the file is located, take a backup of the file in-case of future reference.

Updating the configuration file

Once the files are located, add the below mentioned parameter with its value to the [DEFAULT] section of the configuration file. serial_vm_backup=true

After successfully updating the file, restart the services or containers and these steps need to be followed on all the controller plane.
