Invalidation data area for cache

A method for recovery of a cache, the method comprising:

• determining an initial reconstruction of the cache based on a journal of the cache, wherein one or more journal blocks are associated with the journal, and wherein the one or more journal blocks are represented by one or more mapped journal blocks associated with an invalidation record in an invalidation data area of the cache;
• for each of the one or more mapped journal blocks,
• determining whether a corresponding data block tracked in the journal is valid, based on the mapped journal block;
• and
• if the corresponding data block is determined not to be valid, evicting the corresponding data block from the initial reconstruction of the cache.

A system for recovery of a cache, the system comprising:

• a cache comprising a journal and an invalidation data area;
• and
• a means for:
• determining an initial reconstruction of the cache based on the journal of the cache, wherein one or more journal blocks are associated with the journal, and wherein the one or more journal blocks are represented by one or more mapped journal blocks associated with an invalidation record in the invalidation data area of the cache;
• for each of the one or more mapped journal blocks,
• determining whether a corresponding data block tracked in the journal is valid, based on the mapped journal block;
• and
• if the corresponding data block is determined not to be valid, evicting the corresponding data block from the initial reconstruction of the cache.
