I've written a batch file that uses 7-zip to compress a project folder: View attachment proj_backup.7z It doesn't include the XPacks because they are huge. Instead it makes a list of XPacks required by the project, so if you need to restore the backup, you can consult the list to see what .zip files you need. In order to extract the above file, you'll need to install 7zip, which is free. Get it here. The readme contains instructions. You just need to tell it where your projects/btb folders are, along with the location of 7zip. It also comes with an option to add the current date to the backup's filename, so you can have one backup for each day.
