#### What is AES-256-GCM?

Currently, backups use the [`AES-256-GCM`](https://en.wikipedia.org/wiki/Advanced_Encryption_Standard) encryption algorithm. While this is a highly secure option, it does have a file size limitation of 64 GiB. This isn't an issue when working with Amazon S3, as the data is split into smaller blocks, making it fully compatible with the platform.

While this is a highly secure option, it does have a file size limitation of 64 GiB. This isn't an issue when working with incremental backups, as the data is split into smaller blocks, making it fully compatible with any remote ( S3 compatible or file based).
Full backups creates one file per backup with all the data , that can go over 64GB, even when using xcp-ng zstd encryption
