I am trying to backup a feature service with attachments.
Both the export data (from the details page) and the Create Replica (from the REST endpoint) fail.
It is only 1500 features but some of the attachments are pretty large.
I was able to export the features in ArcGIS Pro but I am unable to export the attachments.
When I look at the table online it 'appears' that some of the features are missing although they all show up in the maps.
Any help is appreciated.
See screen grabs for settings in the create replica.
