As far as storage limitations in various editions, you can find the feature matrix at the bottom of this page: https://www.cloudberrylab.com/backup/windows.aspx

Regarding copying of data to S3: CloudBerry Backup is a backup product, not a file sync tool. So each file needs to be processed, logged, and moved to the backup storage in our backup format. From that point, you can manage version retention and backups of new versions and new files and restore needed versions when needed. It's not possible to use already uploaded versions of the files in their native formats. But once the backup is complete, you can opt to manually remove the old file copies in S3.

File Sync is not really backup, but if it's what you really need, then another product is probably in order. If you want to describe your particular needs in more detail, we can provide additional guidance.

BTW, it sounds like from your description, backup is what you need, but you'll have to use Ultimate Edition with the data set sizes you have.

ok thank you for the info. when you say "in our backup format" what do you mean? I just want a way to run auto backups on a particular folder that then gets uploaded to our s3 bucket.

Then we're a good fit. You mentioned files were already copied to S3 and wanted to understand why they were being backed up if already in the S3 bucket. My comment was related to us requiring the backup file to be in our format I stead of simple copies you may have moved to S3. If I misunderstood, let me know.
