How well does the JR Smith 'Floodgate' system work compared to a check valve with a manual override in preventing sewer backup during heavy rains?

The 'Floodgate' closes automatically without the use of electronics or manual manipulation and reopens once the backflow conditions have subsided. This is advantageous in the event a backflow condition occurs when no one is available to manually close a 'manual check' valve. An alarm is available for the 'Floodgate' requiring a 110V circuit. The selction of either is a personal preference of the end user and their specific application. More info is available on the 'Floodgate' on Jay R. Smith's web site at www.jrsmith.com . == ==

What three levels of backup may be used in database recovery management?
Three common levels of backup used in database recovery management are: Full Backup: This is the most comprehensive backup, creating a complete copy of all your database data and structures at a specific point in time. It serves as a complete snapshot of your database and is essential for recovering from major data loss events like hardware failures or accidental deletions. Differential Backup: This type of backup captures only the data that has changed since the last full backup. This reduces storage space compared to full backups but still allows you to recover from data loss since the last full backup. Incremental Backup: This is the most frequent backup type, capturing only the data that has changed since the last backup (full or differential). It requires a full backup to be present initially and subsequent incremental backups build upon it. This offers the most granular recovery options but requires the most storage space to maintain a complete backup set.

Auto backup system use an original file format (suffix is dwh) which is a new vector drawing format created by GstarCAD. Compared with dwg file it creases the auto backup speed. For example: the backup speed is about 1 second if the file size is within 10M. this make timely backup system be at real time(such as: make a auto backup each 5 minutes)
