Just a question that I hop you can confirm:
I am updating Akeeba to use the new S3 upload instead of the S3 legacy method that I'm currently using on all my sites.
The first site I tried this on the backup initially failed to transfer to S3 because of the following message:

Amazon S3 returned an error message: 0 :: The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'eu-west-1'

Failed to process file xxxxxx.20150625-075738.jpa

Post-processing interrupted -- no more files will be transferred


I managed to solve the issue by setting the Amazon S3 Region to the one I actually use. I found this a bit confusing, as the configuration screen specifically mentions not to use this field unless I use Signature method v2 or v3https, while I left this on the default v4.
(see attachment for screenprint)

I would just like to confirm that this is the way to go for my other 30 sites before I continue.

No, the documentation says the exact opposite of what you understood. You have to set the region if you are using the v4 authentication method. It is ignored only you use v2 or v3https.

S3 Legacy used the v2 authentication which did global authentication: you would authenticate against any and all regions. The v4 authentication method has moved away from global authentication. It does per-region authentication. The region you've chosen for the authentication must match the region the bucket is stored in. I assume this was required for Amazon to do business behind the Great Chinese Firewall and also offer its government cloud services. The rest of us simply have to suffer.
