A second epoch column pair includes a second global identification having second maximum value. The first epoch column pair receives first snapshots, and the first global ID increases with each of the first snapshots. When first global ID reaches first maximum value minus 1, switch to the second epoch column pair. The second epoch column pair receives second snapshots, and second global ID increases with each of the second snapshots. First global ID and first epoch column pair are reset, based on conditions. When second global ID reaches first maximum value minus 1, switch back to first epoch column pair. The first epoch column pair again receives first snapshots, and the first global ID increases with each of the second snapshots.
