Solution DBShadow
Traditional High Availability solutions are failing to protect against logical system failures (human error, software error). With DBShadow in place you are protected against any incident, because your database is mirrored with a time delay – fully automated. In case of a logical or physical failure, you can simply switch to the mirror system and restore to the very latest consistent state of your database; and all of that within a couple of minutes.
The time-delayed database mirror resides on a second server and can be anywhere in your Local Area Network (LAN) or Wide Area Network (WAN). The mirror database is deliberately delayed with a time-lag of for example four hours. However, all changes from the production database up to the current time are available on the mirror server, but just not in the database. In case of a crash, all remaining changes which should be applied are recovered within a very short timeframe and operation continues on the mirror server.
