We have one database with 7 terminals and it seems to unregister the terminals each day. This issue started to occur when we implemented two new tills into the restaurant. unfortunately when we installed the two new terminals we didnt realise that we put a later version of samba onto them we also never noticed the migrate database option when we installed them. So we have no previous backup of the system to revert to.
We are running the latest version which is 5.1.62 and we run a full system backup every night and also a sql database back up as well. The issue never occurred for the first two weeks so the backups where overwritten.
I stopped the system from taking backups as that was a fix suggestion for this issue.
Any more help or suggestions would be great,
