How do I backup my instance? How do I restore everything to that backup point after making any kind of changes?

How do I restore everything to that backup point after making any kind of changes in any of these?

ServiceNow automatically makes backups for you.

You can request a restore of a backup from ServiceNow Support:

https://support.servicenow.com/hisp

In addition to the backup, changes you make get captured in Update Sets. You can export update sets that are in the State 'Complete'. Make sure you do not set the Default update set to 'Complete'.

If you are new to this, have a look at developer.servicenow.com/

If you want to revert 1 single change or small number of changes, consider manually undoing the thing you did and move both the doing and undoing to an updateset you will not commit to any other environment.

I don't think restoring a backup is the way forward with this.

Just to check: it looks like you want to make a few changes, see the result and then possible revert these changes, in case they didn't do what you want.

You should be able to use update sets for this. With update sets you're able to record your changes and if you don't like them 'back out' of them and revert these changes. Please note that update sets don't usually capture changes within the content of a table (such as an incident e.d.).

For more information on update sets: https://docs.servicenow.com/bundle/paris-application-development/page/build/system-update-sets/task/...

If you do want to go with a backup / restore, this is possible with a request from the support-portal (hi portal). On the support-portal it will show you the available restore options. This isn't possible with a personal developer instance (in case you're using one of those).
