* Introduce Volume sub-interface The Volume interface defines APIs to access a storage provider's volume (disk) capacity, usage, etc.. It is inherited by the Storage interface, and is at the same hierarchical level as the Reader interface. * Add validations for new Volume method: Check that GetCapacity() either returns `ErrNotAVolume`, or that it returns a Capacity struct with values that make sense. * Implement default (passthrough) GetCapacity: Cloud providers do not have finite volumes, and WebDAV volumes have no notion of volume size and usage. These implementations should just return an error (ErrNotAVolume) when their GetCapacity() is called. * Implement GetCapacity for sftp storage: Uses the sftp.Client interface * Implement GetCapacity for logging, readonly store * Implement GetCapacity() for blobtesting implementations * Implement GetCapacity() for Google Drive: Also modifies GetDriveClient to return the entire service instead of just the Files client. * Implemented GetCapacity() for filesystem storage: Implemented the function in a seperate file for each OS/architecture (Unix, OpenBSD, Windows).
Kopia
n.
Kopia is a simple, cross-platform tool for managing encrypted backups in the cloud. It provides fast, incremental backups, secure, client-side end-to-end encryption, compression and data deduplication.
Unlike other cloud backup solutions, the user is in full control of the backup storage and responsible for purchasing one of the cloud storage products (such as Google Cloud Storage), which offer great durability and availability for the data.
