You can either:
1. (Recommended) Install PHP 64-bit. PHP 7 is the first official version of PHP with 64-bit support for Windows, and it is available for download from PHP’s official website:

          No, we do not recommend people to delete their data.
          Instead, we recommend people to use PHP 64 bit.
          These are limits imposed by the PHP programming language.

    Hi. I just purchased and am using the Unlimited version, and have had no problem with the backup of 1.98 GB, but continue to get the 512 MB maximum size error. I’m running on a LAMP stack on the Raspberry Pi, which uses a an ARM processor but 32-bit Raspbian OS. So, I can’t upgrade to the 64 bit PHP at the moment. If the 2GB size is the problem, what’s the easiest way to make smaller backups? Do I need to move a bunch of content (e.g, jpgs and mp4s) into my home directory, run the backup/restore, and then copy those files back to the appropriate directory?

    Thanks, and let me know the best approach.
