Multi-Site Sync for LTO is a synchronization service that links multiple S3 enabled LTO archives, creating a single global file system accessible anywhere worldwide. As soon as a file is archived to LTO at one location, it becomes available as a stub file within the global file system. When a user makes a change by writing, overwriting or deleting a file, that change is propagated to all locations. This provides a consistent up-to-date set of files across the entire distributed organization.
When files are restored from another location, they are transferred directly using peer to peer multi-threaded HTTPS which delivers secure fast file transfers. The Multi-Site Sync service uses a cloud database, but the files themselves are never stored in public cloud object storage, avoiding cloud storage and egress fees. Furthermore, because the new service only synchronizes file system metadata, it requires minimal Internet bandwidth.
