So at work, I usually use ACR as a quick means to get my photos directly into photoshop (as i don't usually have the time or want to put in the effort of dealing with LR Classic).

My question is regarding ACR and recovery of edits if ACR crashes or closes unexpectedly. I know that LR Classic writes the edits to the database as you do them, and you can set it to write the changes to an XMP file as well (if you're working with a RAW File) but does ACR have some means of recovery after a crash, even if it means having to redo the last few steps of say a longer edit session (that might include quite a few other edits)?

So far, the best thing I can think of to protect against this is to click "Done" periodically and let ACR save the changes to an XMP file, and then re-open and continue working. Would be nice if it had some sort of edit cache that it could save and that could be recovered if it crashed, even if it wrote a temporary XMP file that would be then removed when you clicked Open, Cancel or Done (if you clicked Done, all of your edits would be saved to a regular XMP file and the temporary XMP file would then be deleted).

If you periodically do an "Export Settings to XMP" in the Settings menu that should survive a crash. You can also create snapshots and update specific ones during the course of your ACR edit session, but that involves a little more work to name the snapshot. I haven't confirmed but I'd assume that snapshots also survive crashes. I'm not aware of any way to automate a save process during an ACR session. The general philosophy around ACR/PS has always been to do the basic raw conversion stuff in ACR to create a fairly neutral starting point for the substantive edits in PS, where there's a lot more available. Of course, the functional division between what you can (should?) do in ACR vs. PS has been eroded over the years as ACR has become more feature rich. It's somewhat of a workflow preference thing, but remember that most of the newer edit capabilities built into ACR don't have to be applied during the initial conversion step. You can always go back into ACR (as a filter) later and utilize these RGB edit features with really no downside and several potential functional advantages (mainly related to layers).

But I thought that ACR doesn't write any changes (ie. save them) until you either opend the image in PS or clicked Done (and close ACR "gracefully").

As far as I'm aware ACR does not write any changes during the initial processing session AUTOMATICALLY. However, you can manually force a creation and/or save to an XMP by manually selecting the Export Settings to XMP. The same applies to the creation of a snapshot. I just confirmed that the Export Settings to XMP immediately creates an XMP file during an initial ACR session for a raw file that hasn't been previously processed. The XMP file is created/saved immediately upon the Export setting being selected. The only real shortcoming is that it's not an automatic/timed save. You have to invoke it manually. Nonetheless, the Export operation is easier than actually opening the processed raw in PS or saving/closing/reopening the raw file in ACR, which I believe is what you were previously doing..
