Method and apparatus for data loss assessment

A data recovery system, comprising:

• a disaster-proof casing;
• a wireless transceiver contained within the disaster-proof casing and configured to receive recurring wireless signals from a primary application server and from a primary storage system that are collocated with the disaster-proof storage unit at a local site, the primary application server configured to store data to the primary storage system, and to mirror the data to a secondary storage system at a remote site, each of the wireless signals indicating a status of the primary application server or the primary storage system at a given time;
• a memory contained within the disaster-proof casing;
• a secure processor contained within the disaster-proof casing and configured to store, to the memory, a status log comprising the respective statuses of the primary application server and the primary storage system at the received times;
• and
• circuitry configured to analyze, subsequent to failures of the primary application server, the primary storage system and the mirroring, the status log to compute a data loss at the local site resulting from the failures of the primary application server, the primary storage system, and the mirroring.

A computer software product, the product comprising a non-transitory computer-readable medium, in which program instructions are stored, which instructions, when read by a computer, cause the computer:

• to receive, by a processor housed in a disaster-proof casing located at a local site, recurring wireless signals from a primary application server and from a primary storage system that are collocated with the disaster-proof casing at the local site, the primary application server configured to store data to the primary storage system, and to mirror the data to a secondary storage system at a remote site, each of the wireless signals indicating a status of the primary application server or the primary storage system at a given time;
• to store, to a memory in the disaster-proof casing, a status log comprising the respective statuses of the primary application server and the primary storage system at the received times;
• and
• subsequent to failures of the primary application server, the primary storage system and the mirroring, to analyze the status log to compute a data loss at the local site resulting from the failures of the primary application server and the primary storage system, and the mirroring.
