When backing up to remote servers, do I have to trust the remote server?
------------------------------------------------------------------------
-Proxmox Backup Server supports client-side encryption, meaning your data is
-encrypted before it reaches the server. Thus, in the event that an attacker
-gains access to the server, they will not be able to read the data.
+Proxmox Backup Server transfers data via `Transport Layer Security (TLS)
+<https://en.wikipedia.org/wiki/Transport_Layer_Security>`_ and additionally
+supports client-side encryption. This means that data is transferred securely
+and can be encrypted before it reaches the server. Thus, in the event that an
+attacker gains access to the server or any point of the network, they will not
+be able to read the data.
.. note:: Encryption is not enabled by default. To set up encryption, see the
`Encryption
encryption (AE_). Using :term:`Rust` as the implementation language guarantees high
performance, low resource usage, and a safe, high-quality codebase.
-Proxmox Backup uses state of the art cryptography for client communication and
-backup content :ref:`encryption <encryption>`. Encryption is done on the
-client side, making it safer to back up data to targets that are not fully
-trusted.

several gigabytes of data per second.
:Encryption: Backups can be encrypted on the client-side, using AES-256 in
- Galois/Counter Mode (GCM_) mode. This authenticated encryption (AE_) mode
- provides very high performance on modern hardware.
