Integrating resources at a backup site

A method, comprising:

• detecting when a primary site is online and offline;
• generating, on the primary site in response to the primary site being back online, a set of sixth storage snapshots by combining a set of fifth storage snapshots that includes a second snapshot format utilized on a backup site and incremental changes to mirrored data on the backup site while the primary site is offline, the sixth storage snapshots including the second snapshot format;
• converting the set of sixth storage snapshots from the second snapshot format to a first snapshot format utilized on the primary site to generate a set of seventh storage snapshots that includes the first snapshot format on the primary site;
• and
• converting, on the backup site in response to the primary site being back online, a set of fourth storage snapshots including the incremental changes and the second snapshot format to the first snapshot format to generate a set of eighth storage snapshots that includes the first snapshot format on the backup,
• wherein:
• the set of seventh storage snapshots and the eighth storage snapshots include a same snapshot format and represent a same data, and data stored on the primary site and the backup site are synchronized prior to the primary site resuming operations in a normal mode subsequent to the primary site being back online.

A computer program product comprising a computer-readable storage medium including program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• detect when a primary site is online and offline;
• generate, on the primary site in response to the primary site being back online, a set of sixth storage snapshots by combining a set of fifth storage snapshots that includes a second snapshot format utilized on a backup site and incremental changes to mirrored data on the backup site while the primary site is offline, the sixth storage snapshots including the second snapshot format;
• convert the set of sixth storage snapshots from the second snapshot format to a first snapshot format utilized on the primary site to generate a set of seventh storage snapshots that includes the first snapshot format on the primary site;
• and
• convert, on the backup site in response to the primary site being back online, a set of fourth storage snapshots including the incremental changes and the second snapshot format to the first snapshot format to generate a set of eighth storage snapshots that includes the first snapshot format on the backup site,
• wherein:
• the set of seventh storage snapshots and the eighth storage snapshots include a same snapshot format and represent a same data, and data stored on the primary site and the backup site are synchronized prior to the primary site resuming operations in a normal mode subsequent to the primary site being back online.
• converting the set of sixth storage snapshots from the second snapshot format to a first snapshot format utilized on the primary site to generate a set of seventh storage snapshots that includes the first snapshot format on the primary site;
