I’d quickly go grab the files in the “autobackup” directory under “{Install Dir}\contexts\main\db\autobackup” and copy them aside. Upload the oldest and most recent to the uploads area using ticket id #1887.
You should probably also shut down the gateway and zip up the main files in that “db” directory (just the various “settings” files) and upload that as well.
Hopefully it’s something easy enough to recover from.
