摘要
Techniques for performing a restoration may include: creating a first snapshot of a primary file system at a first point in time; and at a second point in time, performing first processing to restore at least a portion of the primary file system from the first point in time. The first processing may include: creating a second snapshot of the first snapshot of the primary file system; exporting the second snapshot as a first target device; mounting the first target device as a read-write checkpoint file system; performing file system consistency processing on the read-write checkpoint file system; and subsequent to performing the file system consistency processing on the read-write checkpoint file system, restoring at least a portion of the primary file system from the second snapshot using the read-write checkpoint file system. The file system consistency processing may include correcting metadata inconsistencies of the read-write checkpoint file system.
