There are three types of storage.
DR/Backup Storage: A mirrored storage volume that may contain LUNs, data stores, and file shares. DR/Backup storage is created by Acronis engineers to backup unified storage devices, it contains block-level snapshots.
File Archived Storage (File Level Backup): Cloud-based clustered distributed object storage. The client’s Local Cloud Hub periodically backs up the client’s CIFS shares into this storage. Files are automatically versioned and retained according to a defined retention schedule. Individual files and folders can be restored back to either the original location or to an alternative location. File Archived storage is created on the Storage page.
Primary Storage: A LUN that has been created from the remote cloud storage and made available via iSCSI target. Primary storage is created on the Storage page.
