BLS-2023 has changed how leagues are backed up to Dropbox, Google Drive and Microsoft OneDrive compared to past major versions.
To save your backups to Dropbox, you must have Dropbox software installed on the computer with the Dropbox software logged into your account.
To save your backups to Google Drive, you must have Google Drive software installed on the computer with the Google Drive software logged into your Google account.
To save your backups to Microsoft OneDrive, you must have the Microsoft OneDrive software installed on the computer with the Microsoft OneDrive software logged into your Microsoft account.
In the BLS Program Preferences, you can enable the backups to also go to the above services, but you must point BLS to the folder that is synchronized with your Dropbox, Google Drive or Microsoft One Drive account.
For example, if your Dropbox account is synchronized with the C:\Dropbox folder, you could create a folder inside that to be C:\Dropbox\BLS2023Backups and then point BLS-2023 to C:\Dropbox\BLS2023Backups. When backing up to Dropbox, BLS will create the backup of the league and save to that folder, which then Dropbox will synchronize with the cloud.
The same principle for Dropbox applies to Google Drive and Microsoft OneDrive.
