Backup File Not Present

Started a backup, checked it was running in Operations, and there were no errors in the logs. After the compressing message, checked the folder specified in settings, no backup archive to be found. Changed the folder directories,
Was able to zip up the database with external tool.
Recently installed latest 7z, might that be a problem?

Feature request: after creating a Backup, an option in Settings to open the backup file with archive program user has installed (if any).

Edit: restarting EM Client, and changed the backup folder to C:\Users\My_USER_NAME\OneDrive\Documents\eM Client
and got a backup file! How odd.
