There are several things to try here.

First, try to use the JPA format instead of the ZIP format. It's much less resource-intensive.

If that doesn't work, try setting the following:
- Minimum execution time: 1 second
- Maximum execution time: 5 seconds
- Runtime bias: 50%

If this still doesn't work, take a look at the t3-assets directory on your site's root. How many files does it have? If you see several hundred files (rule of thumb: over 500) it is possible that you will run out of memory or time when Akeeba Backup is listing its contents. I see that you have adequate PHP memory available (64Mb, which is plenty) and a slow-ish host, so my guess is that too many files will cause a timeout. There are two things to try:
- Ask your host about the proper way to increase the PHP max_execution_time to 30 or 60 seconds.
- If nothing else is possible, skip backing up the t3_assets directory using the "Files and Directories Exclusion" button in Akeeba Backup's Control Panel page.
