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.
