My Cloud 4100 Pro backup questions

Although you could use cloudberry on the servers to backup to a MY Cloud, and then upload to S3, I would suggest using a NAS such as a Synology that can run a cloudberry agent and upload to S3/Backblaze etc from the NAS.

However I would suggest looking at whether your Internet upload bandwidth will cope with your daily backup bandwidth requirement.

I am backing up right now using a web based solution. So if I can backup now why would i not be able to to amazon

Well, the difference between fulls, differentials and incrementals spring to mind.

What backup platform are you using at the moment ?

https://www.asigra.com/

I think you might notice quite a change from Asigra (mostly managed) to Cloudberry (managed by yourself), the technology used although "similar" is not "the same", which is why you may experience a difference in backup bandwidth required for backing up to S3.

Although Asigra is (usually) managed in a web browser, it is not a "web based" backup.

Also, we only had a 5mb circuit to the internet  and backed up to a server in California-

I am going to look at other backup programs

if you only have 5Mb/s, unless you only have very small servers, I would think again about online backup unless the backup platform allows you to do an initial onsite backup that is then shipped offsite to form your initial backup there so you are only evenr sending incremental\synthetic full backups.

i had 5mb and we were able to do cloud backup now we have 100 MB. I see no reason we cannot do this ourselves

You had only mentioned having a 5Mb connection.

Cloudberry for NAS (such as for Synology) backs up what is on the NAS. Clioudberry for server backs up directly to cloud.

If you had a NAS with an S3 type API that Cloudberry can interface with, and the capability to run Cloudberry for NAS, then you should be able to acheive what you are after, Unfortunately, the WD My Cloud series does not have either of these capabilities. Therefore to have it in the backup "chain" you would need to use a different backup application (such as SQL backups or Windows Backup) and then another application to upload those backups to S3. As however SQL backups and Windows Backup create monolithic backups, you would in effect be uploading a full for every backup, which a/ uses a lot of bandwidth, and b/ can be quite costly.

I am looking for solutions. We backup to the cloud now so I am aware of the costs. I know what the costs are of not backing up and needed the data too
