Thanks for the question of increasing the BoldGrid Backup plugin from 10 to 15 GB. Currently, the limit is set to 10 GB and cannot be increased in the software. If your site is beyond 10 GB in size, then I would highly recommend using a 3rd party backup option. You can also consult with your host in order to determine if you have any options for backing your site through their services.
Thank you Amel for the prompt and clear answer! C-panel has a file back-up feature which downloads the complete 13 GB BoldGrid site onto my personal computer as a “.tar.gz” file. Can you let me know if having that file would allow me to restore my BoldGrid site? Thanks again!
