Hi Amarjeet Singh, 

Thanks for reaching out. Did you ever find an answer for this issue ? We have this blog available on how to restore your Sage 50 backup file. Sage 50 Canada creates automatic backups when you install an update or upgrade versions. For other daily backups, you would have needed to set up scheduled backups and or create them manually. There's also an option for cloud backups via a Microsoft OneDrive integration subscription.

If you are still looking for guidance, please let us know and we can try to point you in the right direction or suggest some resources or next steps.

Warm Regards,

Erzsi
