Steam Deck Client Channel has received a pretty big update with an exceptional feature of allowing Steam Installs to be transferred between PC's or PC to Steam Deck without the need to re-download, making the transfer a local transfer and not via the Internet.
The new Steam Local Network Game Transfers feature allows Steam users to copy existing Steam game installations and update files from one PC to another over a local area network, without having to download and install from a Steam content server on the internet. This reduces internet traffic and can speed up installs or updates.
The Network Game Transfers feature is currently only PC -> PC or PC -> Steam Deck, and both sender and receiver must have opted into Steam Beta. More details on Steam Local Network Game Transfers can be found here
