Why do more off-site full backups after initial one?
I'm currently experimenting with Backblaze but from your suggestions I'm guessing they might not support Synthetic Full Backups like Amazon and Wasabi. If I were to switch my backup location to Wasabi, do I have to do anything special to enable Synthetic Full Backups? Can you provide a link talking about Synthetic Backups?
Some more about my different clients: Many have low upload speeds (1.5 Mb to 15 Mb) and in the past I was only uploading critical file shared data to the cloud. In the instance of 2 months to complete the initial backup, that client has about 830GB and a 1.5 Mb upload speed. Between my 28 clients they currently backup about 6.5TB of just critical files. However, now that I'm seeing how cheap cloud storage is, I thought I would try and do full image based backups of servers vs. just critical data.
So it sounds like if I did Wasabi with Cloudberry I could setup my backup plan to do a full Synthetic Backup each month and incrementals in between. This would then satisfy having a full server backup in the cloud, and as long as there is not tremendous change in the data, they should be quick to do the full backups?
