There are some user environments where backups are created automatically on a periodic basis by operating system or third-party backup software. If that software backs up hot NV2 databases then integrity could be lost in the backup copy and you will not discover this until it is too late; i.e. when you try to recover from a backup copy. Such software may work for applications that load and store files in one operation, not keeping them open, but they can be unsuitable for database-oriented products like NewViews.
A second difference between NewViews and third-party backups is that NewViews performs low level integrity checks (i.e. checksums) as it backs up. This results in the earliest possible detection of random overwrites of NewViews databases, and also ensures that backups never contain these overwrites. Otherwise random overwrites would be discovered only when attempting to recover, which is just about the worst possible time. Therefore, even if you use third-party backup software, we recommend that you create additional backups using NewViews.
