How to use Walrus for private file storage and ensure fault tolerance?

I'm running a Walrus publisher daemon on my PC, and I want to store files with private visibility. What are the steps to configure this? Additionally, I am curious about the fault tolerance measures in Walrus, especially if I need to run multiple storage nodes similar to an IPFS cluster.

Walrus implements fault tolerance by sharding and replicating your data across the network. Typically, it creates 4-5 copies of each data shard, ensuring that you can recover your data even if up to 2/3 of the network fails. Regarding the need to run multiple storage nodes: Walrus does not require you to operate multiple nodes yourself to achieve fault tolerance. It already spreads chunks of your data across various nodes in the network. This is a key difference from solutions like IPFS clusters, where users must manage their own redundancy.

To ensure private visibility when storing files on Walrus, you need to encrypt the files before uploading them, as Walrus does not provide native encryption. You can use the Seal framework, which offers threshold encryption and on-chain access control to keep the decryption logic secure while using Walrus for storage.

Walrus is a decentralized storage and data availability protocol designed specifically for large binary files, or "blobs"
