1. A method of local seeding of a restore storage for restoring a backup from a remote deduplication vault storage, the method comprising:

  • storing, in a remote deduplication vault storage that is remote from a restore storage, an image-based backup of a source storage, the image-based backup including unique blocks that were stored in the source storage at a point in time;

    storing a list of the blocks that were stored in the source storage at the point in time;

    storing positions of the blocks that were stored in the source storage at the point in time;

    storing, in a local seeded storage that is local to the restore storage, common blocks;

    determining which of the blocks included in the list are available in the local seeded storage as locally available blocks;

    determining which of the blocks included in the list are only available in the remote deduplication vault storage as non-locally available blocks;

    reading the locally available blocks from the local seeded storage;

    reading the non-locally available blocks from the remote deduplication vault storage; and

    storing the read locally available blocks and the read non-locally available blocks in the restore storage in the same positions as stored in the source storage at the point in time.
