LRU dump backup

Percona XtraBackup includes a saved buffer pool dump into a backup to enable reducing the warm up time. It restores the buffer pool state from ib_buffer_pool file after restart. Percona XtraBackup discovers ib_buffer_pool and backs it up automatically.


If the buffer restore option is enabled in my.cnf buffer pool will be in the warm state after backup is restored.
