What is hot backup?

In case of system crashes, hardware failures or deleting data by mistake, backup is crucial. There are primarily two types of backups no matter you perform a system backup, disk backup or file backup. One is cold backup, performed when the database is offline, namely all the data is not accessible to the users while the backup is in process, the other is hot backup, a technique to perform the backup while system is running normally, even if the data to be backed up is being read, updated, or edited by the users.

For those whose system must be running 24 hours a day, 7 days a week, whose data need to be updated frequently, or who run a multi-user system, a hot backup is a better backup solution. Comparing hot backup and cold backup, you can find a hot backup more convenient in many ways. You may also know hot backup as a dynamic backup or active backup.
