Email-Based Backup Data Conveyance for Offline Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network-based backup systems cannot perform backups or restores on portable computing devices when they are not connected to the network, leaving data vulnerable and users without access to critical information.
Innovation Solution
Implementing a method that uses email to convey backup and restore data and metadata between a backup client and a backup server, allowing data to be backed up and restored even when the device is not connected to the network by sending emails with encrypted data and metadata through standard email protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a network-based backup system is implemented, then data can be backed up and restored when devices are connected to the network, but portable devices cannot perform backup or restore operations when they are not connected to the network
Solution Approach 1:
The patent uses email as an intermediary communication channel between the portable device and the backup server. When the portable device is offline, it can still send backup requests and receive restore data through email, which acts as a mediator that does not require direct network connectivity between the device and backup system.
Solution Approach 2:
The system performs preliminary actions by storing backup data and metadata in email messages that are queued and sent when the device is offline. The backup data is prepared and attached to email messages in advance, allowing the device to synchronize with the backup system whenever it reconnects without requiring continuous network connectivity.
2Adaptability or versatility
If email is used to convey backup data, then portable devices can perform backup and restore operations offline, but data transmission through email may affect transmission speed and efficiency
Solution Approach 1:
The patent applies partial action by transmitting only the necessary backup data and metadata through email, rather than continuously syncing all data. Email is used as a supplementary channel for offline operations, while the primary fast network connection is used for regular synchronized backups when available.
Data Source
AI summary
Various methods and systems for using email to convey backup and restore data are disclosed. One method involves: receiving a request to perform a backup system operation; generating an email that includes data and metadata (which is associated with the data); and sending the email to an email address associated with a backup system component. The request can be a backup request, in which case the data includes data to be backed up, and the backup system component is a backup server. Alternatively, the request can be receiving a restore request. In this scenario, the data includes data to be restored, and the backup system component is a backup client.
