The AF XML Import/Export is described by OSIsoft as a tool for backing up and restoring an AF database to either the same server or a different server. However, one object relationship that is not included in the XML file is an Event Frame's reference to the Analysis that created it. As a result, when the AF database is restored to a new database, if an Analysis backfill is performed that would otherwise delete existing Event Frames, the Event Frames that have lost their Analysis reference will not be deleted. This has been on OSIsoft’s internal known issue list since 2016-01-29 and was only made public in 2019-02-11 when we discovered it - https://techsupport.osisoft.com/Troubleshooting/Known-Issues/81334. Techsupport Case #954337. Please vote to raise the priority of this issue so that it gets addressed soon.
