As you can tell, this site is in need of migration to current versions. Rather than do this on the production site, I want to do the migration in a development site in case of issues. Toward that end, the first step was to use Akeeba for the backup. However, the file was not created because of size (114 GB). Previous backups (over three years old) are just shy of 600 MB. I attach the log file of the failed backup.
Can I accomplish my goal of restoring the site using the option to "backup main site database (SQL only)"? This process worked today (I tried to upload a 2nd zipped logfile, but could not). If you need it, let me know how to provide it.
