Preservation of electronic messages between snapshots

A data management system, comprising:

• a memory buffer;
• and
• one or more processors in communication with the memory buffer configured to acquire a first snapshot of a set of electronic messages, the first snapshot comprises a state of the set of electronic messages at a first point in time, the one or more processors configured to detect that a first electronic message was received subsequent to the first point in time and write the first electronic message to the memory buffer, the one or more processors configured to acquire a second snapshot of the set of electronic messages subsequent to writing the first electronic message to the memory buffer, the second snapshot comprises a state of the set of electronic messages at a second point in time subsequent to the first point in time, the one or more processors configured to compare electronic messages stored within the memory buffer with electronic messages within the second snapshot of the set of electronic messages, the one or more processors configured to detect that the second snapshot of the set of electronic messages does not include the first electronic message based on the comparison of the electronic messages stored within the memory buffer with the electronic messages within the second snapshot of the set of electronic messages, the one or more processors configured to store the first electronic message within a buffer snapshot in response to detection that the second snapshot of the set of electronic messages does not include the first electronic message and delete the first electronic message from the memory buffer subsequent to the first electronic message being stored within the buffer snapshot.

One or more storage devices containing processor readable code for programming one or more processors to perform a method for operating a data management system, the processor readable code comprising:

• processor readable code configured to acquire a first snapshot of a set of electronic messages, the first snapshot comprises a state of the set of electronic messages at a first point in time;
• processor readable code configured to detect that a first electronic message was received subsequent to the first point in time;
• processor readable code configured to buffer the first electronic message using a memory buffer in response to detection that the first electronic message was received subsequent to the first point in time;
• processor readable code configured to acquire a second snapshot of the set of electronic messages subsequent to buffering the first electronic message using the memory buffer, the second snapshot comprises a state of the set of electronic messages at a second point in time subsequent to the first point in time;
• processor readable code configured to compare electronic messages stored within the memory buffer with electronic messages within the second snapshot of the set of electronic messages;
• processor readable code configured to detect that the second snapshot of the set of electronic messages does not include the first electronic message based on the comparison of the electronic messages stored within the memory buffer with the electronic messages within the second snapshot of the set of electronic messages;
• processor readable code configured to store the first electronic message within a buffer snapshot in response to detection that the second snapshot of the set of electronic messages does not include the first electronic message;
• and
• processor readable code configured to delete the first electronic message from the memory buffer subsequent to storing the first electronic message within the buffer snapshot.
