Cold backup

What is cold backup?
A cold backup is a backup that is performed while a database or system is offline or in shutdown mode. In contrast, other types of backups can be performed while a database is running and data is flowing into or out of the database or data warehouse structure.

The idea behind cold backup is that if the backup occurs while a database is not, it is easier to back up some files and forms of information that are at risk if the backup attempt is made while those files are in progress runs.

Experts have discussed certain scenarios and operating systems (OS) where cold backup might be a better option. On the other hand, the main disadvantage of cold backup is that a system essentially has to stop in order to restore data.

Einige Manager umgehen die Idee von Ausfallzeiten, indem sie Cold-Backups in ruhenden Schichten durchführen, wenn die Datenaktivität bereits sehr niedrig oder nicht vorhanden ist. Kalte Sicherungen können für die Notfallwiederherstellung und andere Pläne zum Schutz wertvoller Daten nützlich sein und können mit verschiedenen Sicherungsmedien wie Band oder Platten oder durch Routing von Daten aus der Offline-Datenbank an ein Cloud-Hosting-System durchgeführt werden.
