Please read this page https://www.akeebabackup.com/documentation/akeeba-backup-documentation/step-by-step-guides.html#how-to-cloud-backup I already describe the relation between size of uploads, upload time and server configuration:

We will have to change just one option: Part size for archive splitting. Select the "Custom..." option and type in 20 in the text box that appears to the right of the drop-down. This setting will chunk our backup archive into multiple files, the maximum size of each one being the value of this setting.



You might wonder why we need to do that. PHP always has a strict time limit, i.e. the maximum time a PHP page may process data before the web server aborts it. Uploading the backup archives to cloud storage takes time, the exact amount of which depends on the size of the file and the network speed. The time limit and the bandwidth are beyond our control, so we can change the only parameter we can touch in order to avoid timeouts: the file size. Akeeba Backup Professional is smart enough to upload each part of the backup archive on a PHP page load of each own, so as to avoid timing out.

So, if you want to make sure that your uploads which happen during the backup process can complete you should try decreasing the part size to 1Mb or smaller or use a different web or FTP server that is much, much faster. Since the source of the issue lies in the network speed and server setup it's NOT a bug in Akeeba Backup and cannot be fixed. WE ARE NEITHER YOUR HOST NOR YOUR FTP PROVIDER.

And just because there is an option for something that doesn't mean it will work when the outside conditions are impossible. For example, my car has 6 gears. If it's snowing and road is icy I cannot reasonably expect to drive in sixth gear at speeds in excess of 100 Km/h. The fact that the car cannot comply with my wish due to external conditions doesn't make the car broken and in need of a repair. I expect that by the next release of Akeeba Backup you'll have fixed your expectations to be in accordance with the server environment you are using it in.
