disable synthetic full backups I'm uploading to Glacier Instant Retrieval, and everything is working fine. Initially, when studying the new S3 classes, I understood (incorrectly, I found out later) that "Restore Cost" would be charged when I restored data, and by restore, I understood taking data out of the S3 cloud. With synthetic backups, data is read and duplicated within the S3 cloud, and I (incorrectly) imagined that this would not count as "Restore". However, it do counts. Seems it's more a "READ Cost" than a "Restore Cost". Back to the Synthetic Full, when it happens on a 2TB backup, for example, it work flawlessly, no problem on that, but AWS charges me 2TB of "Read Cost" on the Glacier IR, and my billing there goes crazy.
That's why I'm looking to still keep using Glacier IR, but stop using synthetic backups. I'm OK with reuploading everything, that's not a problem, I just couldn't figure out how to disable it.
The feature is working as expected, there's really no problem on it. Problem is on the S3 Class I choose and, by the workings of the Synthetic Full, it blows my billings there. So I really need to disable it.
