Backup/Restore a single sheet

I make mistakes quite often when editting but I realize perhaps hours later when I have editted many entries in a sheet and perhaps several sheets. I could make a snapshot often when working intensively but If I restore the whole database to recover 2 or 3 entries I can miss the work in other 20 entries and 2 sheets.
I suggest to have the possibility to recover a single sheet and with a different name so that it is not overwritten and can be compared with the old version to find out what has to be changed or updated.

Thank you for your suggestion, I will let our development team know about this and consider it for future enhancements.
