Snapshot storage and management system with indexing and user interface

At least one non-transitory computer-readable storage medium having instructions, which when executed by a processor of a computing device, causes the computing device to perform a method for tracking locations of stored data, the method comprising:

• storing, in a memory, data to indicate that a primary volume is no longer identified by a first logical unit number,
• wherein the primary volume is stored at a first device identified by the first logical unit number;
• storing, in the memory, data to indicate that a recovery volume is no longer identified by a second logical unit number,
• wherein the recovery volume is stored at a second device identified by the second logical unit number;
• and
• storing, in the memory, data to indicate that the recovery volume is identified by the first logical unit number,
• wherein the recovery volume comprises multiple snapshots of the primary volume, and
• wherein the recovery volume is usable as the primary volume after the recovery volume is identified by the first logical unit number, and
• wherein identifying the recovery volume by the first logical unit number is unrelated to a failure status of the primary volume.

A computing system for tracking locations of stored data, comprising:

• means for indicating that a primary volume is no longer identified by a first logical unit number,
• wherein the primary volume is stored at a first device identified by the first logical unit number;
• means for indicating that a recovery volume is no longer identified by a second logical unit number,
• wherein the recovery volume is stored at a second device identified by the second logical unit number;
• and
• means for indicating that the recovery volume is identified by the first logical unit number,
• wherein the recovery volume comprises multiple snapshots of the primary volume,
• wherein the recovery volume is usable as the primary volume after the recovery volume is identified by the first logical unit number, and
• wherein identifying the recovery volume by the first logical unit number is unrelated to a failure status of the primary volume.
