Is there a way to 'rollback' form 2019 to 2018?  

No.  There is no built-in facility in Sage 50 to do that.

Not noticing the mistake, when exiting, I backed up overtop of my 'good' backup and now cannot restore.

I hope that's no longer possible to do with the latest release of Sage 50.  It just should not work that way.  We also use the automated backup to do a backup on closing the program at day end.

There may be an automatic backup, search your home directory for files ending with .CAB, or folders called Backup or Backups.  They may be somewhere in the Simply or Simply Accounting folders.

Murkocat are you still wanting to roll the year back... let me know in this form

Hello, yes, I am still looking for a way to reset the 'fiscal' year without losing any data.

Cannot restore from backup as backup was overwritten two times with the wrong data.

Thank you
