To ensure I don't lose my work, I make a file copy and incorporate the date a new but similar file name:
i.e. done by menu:
File
File Operations
Copy
I also use the suggested backup which auto populates a file name that includes the date.
e.g. Shares 2025_20250518.rkn:
i.e. done by menu:
File
Backup
What are the differences, pros and cons of these methods?
Am I safer to do both as I am always concerned re the possibility of a hardware or software calamity and need to restore?
