Abstract

Described is a system (and method) for cross application granular restore of email attachments backed up to a cloud-based object storage. More particularly, the system may allow various non-email applications to directly restore an email attachment of a backed-up email without requiring restoration of the email itself. The attachment may be a file, item (e.g., contact, event, message, etc.), or another type of attachment such as a link to a file or an item. To provide such a capability, the system may decouple the attachment from an email when performing a backup to an object storage. The system may also store specialized metadata that may be leveraged when performing an efficient restore of the attachment.
