Abstract
Embodiments of the present disclosure relate to a method, device and computer program product for recovering metadata. The method comprises detecting whether first metadata corresponding to a first journal at a first device is corrupted, and obtaining second metadata corresponding to a second journal from a second device in the case that the first metadata is corrupted, wherein the second device is remote from the first device. The method further includes recovering the first metadata based on the second metadata, the first journal and the second journal. Embodiments of the present disclosure utilize remote backup metadata for recovery in the case that local metadata (which for example includes index information) is corrupted without reserving metadata snapshot locally, thereby saving the storage space.
