we have been having our ArcGis pro sessions bomb resulting in corrupt .aprx files.
the backup that we have are sometimes not frequent enough.
is there any where arc gis pro saves a backup of the .aprx file?
if not, how do we get a most recent backup w/out using windows explorer?
Currently there is a BUG-000104539 Implement an equivalent for Save a Copy functionality in ArcGIS Pro listed but it's not the product plan. What you may want to implement is the creation of a Package Project on timed basis to serve as your backup should the original project become corrupted. Hope this helps!
Thomas - for BUG-000104539, this was for ArcGIS Pro 2.0 (April 2017) - so 2+ years ago. Digging deeper into your question, there is an enhancement request ENH-000110189 (Add ability to quickly rename project, project home folder, other related files, toolboxes and default file geodatabase in ArcGIS Pro) that IS listed "In Product Plan" as a result of the ArcGIS Ideas link you listed. So it appears this is coming in a future release of AGP...
