How To Back Up Your OrientDB Databases on Ubuntu 14.04
From the post:
OrientDB is a multi-model, NoSQL database with support for graph and document databases. It is a Java application and can run on any operating system; it’s also fully ACID-complaint with support for multi-master replication.
An OrientDB database can be backed up using a backup script and also via the command line interface, with built-in support for compression of backup files using the ZIP algorithm.
By default, backing up an OrientDB database is a blocking operation — writes to be database are locked until the end of the backup operation, but if the operating system was installed on an LVM partitioning scheme, the backup script can perform a non-blocking backup. LVM is the Linux Logical Volume Manager.
In this article, you’ll learn how to backup your OrientDB database on an Ubuntu 14.04 server.

I don’t know if it is still true, given the rate of data breaches, but failure to maintain useful backups was the #1 cause for sysadmins being fired.
If that is still true today (and it should be), pay attention to proper backup processes! Yes, its unimaginative, tedious, routine, etc. but a life saver when the system crashes.
Don’t buy into the replicas, RAID5, etc., rant. Yes, do all those things plus have physical backups that are store off-site on a regular rotation schedule.
The job you save may well be your own.
