I test each new version of Akeeba Backup this way:
1. Install it on a test site (clone of live site at some point)
2. Do a backup
3. Restore to test site after deleting the test site hierarchy
4. Install on live site
5. Do a backup
6. Restore to test site after deleting the test site hierarchy
Doing this with Backup 8.1.17, I ran into a problem. On step 3, Kickstart gave me an error database support= no, which I'd never seen before. I ignored it, and the restore worked fine.
So it's not a problem for me, but it'd odd, so I'm passing it on.
