A system, method, and non-transitory computer-readable medium provide backup and archive services for computing devices. Typically, multiple backup snapshots are archived together in each archive cycle. A catalogue for the current archive is efficiently created by starting with a copy of the previous archive catalogue and updating it based on metadata associated with the backup snapshots.

Unified time-indexed catalogue for multiple archived snapshots

When a backup client sends a request to back up a file to a backup server, the file and an index (e.g., checksum, hash, encryption, etc.) of the file are stored on the backup server in an efficient deduplication storage. If a backup client sends a request to back up a modified version of a file already stored on a backup server, the modified portion of the file is stored. In addition, an index of the modified portion is generated and stored along with the modified portions on the backup server. The indices can be used to reconstruct the file or modified version of the file when retrieved. The efficient deduplication storage method ensures that multiple copies of files or portions of files do not exist on the servers.
