OTbase Inventory creates automatic backups every 12 hours, and in addition you can manually create a backup at any given time.
Restoring a backup file allows you to arrive at a fully running configuration with the exact data set from the backup time, with an empty OTbase Inventory binary. The backup file not only contains your asset information, but also user and configuration data.
In theory creating a backup image for OTbase Inventory is tricky because it runs in a container. Therefore, the original backup file is residing within the container. As a result, the backup file would be lost in case of a container crash (or VM crash). In order to remedy this, the backup file is also created in a folder outside of the container. This folder is named /var/ot-base/backup, unless you changed the install script.
As you can see, a backup file starts with otbase followed by a version number, the timestamp of creation, and has the extension .data.
You want to make sure that files in this folder are moved to an external location on a regular basis, in order to address catastrophic server failure.
