Abstract: Checking of a database snapshot of an active database is initiated. Thereafter, an anchor page associated with a most recent snapshot that links to a restart page is read. Subsequently, the linked restart page is read. It is then initially determined, based on the reading of the anchor page and the restart page, whether the snapshot is accurate. If it is initially determined that the snapshot is not accurate, the anchor page and the restart page are re-read until a final determination is made that whether the snapshot is accurate. Alternatively, if not is initially determined that the snapshot is accurate, then data is provided (e.g., displayed, loaded into memory, transmitted to a remote computing system, stored in physical persistence, etc.) that indicates that the snapshot is accurate.
