Menu option #6 does not work

[chrisidso]

Saw this on linux (Ubuntu). To repro: Type 2 to add then enter a small number.
When the menu reappears type 6 to create a back up file. I typed 'lion7' ...

Expected: Should allow you to type a file name and then create the desired back up file. Actual: Error message:

Please wait while the database file is backed-up ...

Traceback (most recent call last): File "main.py", line 161, in main(db_file) File "main.py", line 121, in main msg = backup_db(db_file) File "main.py", line 22, in backup_db copyfile(db_file['path'], new_file) File "/home/newton/anaconda3/lib/python3.7/shutil.py", line 121, in copyfile with open(dst, 'wb') as fdst: FileNotFoundError: [Errno 2] No such file or directory: 'db/backup/lion7.sqlite'
