Remote backup to Wasabi, a cost-effective alternative to S3.
This is available with our V2 backups, currently still in beta
This is already implemented. Under downloads (i do not know if it is dev only) there is a plugin. I use wasabi currently on all sites!
One Downside if Wasabi - there is a minimal time you need to pay for uploaded files which is 90 days, regardless if you delete the file earlier. So if you have a 30 Day rotation you pay for another 60 days. I currently try out Backblaze as a replacement (running with the AIO S3 as well)
