Recovery from a system crash

ERPNext
1

I have a situation with a client.

The system is a self hosted solution on Ubuntu Desktop 16.05. I may not have the MariaDB backup file (or even if I do, it may be a few months old), but I should be able to get access to their harddrive and all the contents on that.

Is there anyway I can re-create their instance from that information?

Thanks

Jay

My layman thoughts:

You can try to restore the hard drive to a new system. Once that is done and you are able to start ERPNext on it and if the data is available in the DB then you can just take a backup and restore it on a new server.

Hi Jay

Provided the old hard drive spins up, its contents can be copied to another, to recover all the files necessary to restore the database state at the time of the crash.

MariaDB has tools to check, repair and analyze the database state mysqlcheck - MariaDB Knowledge Base

I have no personal experience repairing, perhaps others can share their experience?
