Akeeba appears to break the backup into three chunks - two 2GB pieces and a 300MB third.
I'm using the command-line akeeba-backup.php script for backups, and specifying the profile number.
It appears backups always timeout during the upload process.
What configuration changes should I make to improve backup reliability?
Also, backup profile #1 has problems. I'd like to delete it, but it won't let me because it's #1. Do I rename it? Can I delete it directly from the filesystem? I've also set #4, the one I've configured properly, to be the default.
This is the cli log from one of the failed backups. The first warning can be ignored.
