There may be instances when a system crashes due some software or hardware failure. To mitigate such risks, and as a part of Business Continuity Process, the following steps can be followed to bring back your DNIF platform up and running on a new system:
Recovering from system crash includes:
- Looking for logs
- Backing up data from the faulty system
- Deploying a fresh copy of DNIF and Docker
- Restoring the backup data on a new system
Looking for logs:
If you encounter a system crash due to a software failure and can manage to log into your system, follow the steps below to locate the log files and identify the issue:
Host Machine Logs: on the host machine, logs can be viewed on the /var/log/ path.
- Docker Container Logs:
- Log into the docker container
- System logs can be viewed at /var/log path.
- DNIF Service Logs:
- Log into the docker container(path to login document)
- DNIF service logs get stored at
In case of a hardware failure, please contact your organization’s data recovery team for further assistance.
Backing up data from faulty system:
This step is only feasible if the HDD or set of HDDs from the host machine server are readable.
This backup has to be done in two parts:
