System and Method for Data Validation between Synced Devices

A method for post-validating data at a remote server after upgrading a syncing application, the method comprising:

• providing a remote server with a mirrored copy of client device stored data, and an upgraded syncing application network-connected to a client device;
• subsequent to updating the syncing application, creating a post-updated server manifest of information derived from the mirrored copy of the client device stored data;
• archiving the mirrored copy of the client device stored data;
• resyncing with the client device;
• receiving a post-updated client manifest derived from data stored at the client device;
• comparing the post-updated client manifest to the post-updated server manifest;
• when the post-updated client manifest fails to match the post-updated server manifest, determining unmatched data;
• and,
• updating the mirrored copy of the client device stored data with the archived unmatched data.

A method for pre-validating data at a client device prior to upgrading a syncing application, the method comprising:

• providing a client device with a local copy of client device stored data, a syncing application network-connected to a remote server with a mirrored copy of the client device stored data, and an uninstalled upgraded syncing application;
• initiating a client device syncing application upgrade;
• suspending syncing with the remote server;
• sending a backup/manifest request to the remote server;
• the remote server creating a server manifest of information derived from the mirrored copy of the client device stored data, including a server checksum;
• the client device creating a client manifest including a client checksum, derived from the local copy of the client device stored data, and sending the client checksum to the remote server;
• the remote server archiving the mirrored copy of the client device stored data;
• the remote server comparing the client checksum to the server checksum;
• and,
• when the client checksum matches the server checksum, the client device receiving directions from the remote server to install the synching application upgrade and resync with the remote server.

A system for pre-validating data at a remote server prior to upgrading a syncing application, the system comprising:

• a remote server;
• a processor;
• a non-transitory memory;
• a validation application embedded in the non-transitory memory and enabled as a sequence of processor executable instructions for pre-validating a mirrored copy of client device data stored in the non-transitory memory prior to upgrading a remote server syncing application;
• wherein the validation application, in response the upgrade being initiated, suspends syncing between the remote server and client device, creates an initial server manifest of information derived from the mirrored copy of the client device stored data, archives the mirrored copy of the client device stored data in the non-transitory archive memory, receives a client manifest derived from data stored at the client device, compares the client manifest to the initial server manifest, and when the client manifest matches the initial server manifest, installs the synching application upgrade and resyncs the remote server with the client device.

A system for pre-validating data at a client device prior to upgrading a syncing application, the system comprising:

• a client device processor;
• a remote server processor;
• a client device non-transitory memory;
• a remote server non-transitory memory;
• a client-side validation application embedded in the client device non-transitory memory and enabled as a sequence of client device processor executable instructions for pre-validating a local copy of client device data stored in the client device non-transitory memory prior to installing a client device syncing application upgrade;
• a server-side validation application embedded in the remote server non-transitory memory and enabled as a sequence of remote server processor executable instructions;
• wherein the client-side validation application, in response to a client device syncing application upgrade being initiated, suspends syncing between the client device and the remote server, and sends a backup/manifest request to the remote server;
• wherein the server-side validation application creates a server manifest of information derived from the mirrored copy of the client device stored data, including a server checksum;
• wherein the client-side validation application creates a client manifest including a client checksum, derived from the local copy of the client device stored data, and sends the client checksum to the remote server;
• and,
• wherein the server-side validation application archives the mirrored copy of the client device stored data in memory, compares the client checksum to the server checksum, and when the client checksum matches the server checksum, sends instructions to the client-side validation application to install the synching application upgrade and resync the client device with the remote server.
