i am constantly making changes to access and excel file macros and databases. what i usually do before i modify the file is i make a copy of the file and rename it to the filename_todaysdate.ext. is this the proper/safest way of doing things?
Your backup strategy is based on copying the entire Excel or Access file … which may be just fine for your requirements. I don’t do much Excel, but with Access there are many times I prefer saving just selected pieces rather than a complete copy of the entire MDB. You can imagine how much disk space would be consumed by multiple copies of a large MDB … say hundreds of megabytes, for example.
You can use the undocumented SaveAsText method to save individual database objects to text files:
O’Reilly’s Access Cookbook offers another granular approach to backing up database objects. See Recipe 6.8 Back Up Selected Objects to Another Database
