How to backup asset data
Are you working on changing asset data in bulk? Are you trying to replace all of your assets?
It’s important to always back up your asset data when you’re making big changes.

Why?
There is no undo button in CORTEX Service when you change or delete your assets.
The only people who can undo your operation is the software’s developer team but this could take sometime for the investigation to happen - we recommend that you contact us in case of major issue. https://adbsafegate.atlassian.net/servicedesk/customer/portal/11
