Virtual file systems

A virtual file system (VFS) is where a virtual site keeps the files of its users. A VFS names a storage backend (a local disk, another SFTP server, an S3 bucket, an Azure container, a Google Cloud Storage bucket, or an R2FS! node) and how to reach it, and can be mounted as a user's home or as a virtual folder inside it. The pages in this group cover the backends that need a little setup on the provider's side, and the features that apply to every VFS:

• Using another SFTP server as storage, the reverse proxy scenario.
• Storing data in Amazon S3, including S3 compatible stores.
• Storing data in Azure Blob Storage.
• Storing data in Google Cloud Storage.
• Encrypting a VFS at rest: what is encrypted, how, and what it costs you.
• Soft and hard quotas: how the two limits behave and how usage is measured.
• Parametric home directories: one VFS, one folder per user.
• Overriding permissions on subfolders: different permissions on different folders of the same home.
