Therefore, data that includes deleted files and blank spaces are also safe.
Create a local cloud server software#
This method somehow blinds the software agent that executes the backup, since it ignores the data of the virtual machine. In case something goes wrong with the backup, the administrator can go back to the saved snapshot and restore. The solution to this scenario was the creation of snapshots: an instant image of a particular moment of the copy of the disk file of the virtual machine.Ī snapshot preserves the file system of the disk as well as the memory of the virtual machine. This situation would affect the performance of all the virtual machines located in the host. Then, the backup administrator would not know in which physical machine the virtual machine is located and this could cause it to program multiple backups of the same host machine. If you follow the traditional backup method of a physical server in a virtual one, the problem would be that the backup software could have some problems to identify if the server is physical or virtual. Virtual serverįrom the conceptual point of view, the backup of a virtual server may seem to be similar to the physical server backup method but entails a greater complexity. It is necessary to mention that each file inside the backup copy is put in a database in case it needs to be restored. Subsequently, the same backup server sends the backup to its final destination.
Then, the software uses an IP network to transfer the copy to the backup server.
Physical serverĪlthough there are several ways to back up a physical server, the most common method requires a software agent in the client that reads and collects the data to back up. Let’s make a comparison between both types of backups to have a clear idea of their differences. The truth is that thanks to the constant development of specialized applications in backups, a cloud server backup is faster and more efficient than the backup of a physical server. If you are not familiar with virtual servers backups, this process may seem complex at first glance.
