A method of versioning provides the grandfather-father-son-principle. Here, numerous backups on different media at set periods of time are made. From the original file, the grandfather, the father file spring and from which, in turn the file of son of. While the younger versions are substituted for short periods of time, the previous are substituted by longer periods of time. So, it can be prevented that files that were destroyed by viruses or application errors, are ever lost. A virtualization software, such as for example, Hyper-V for Windows Server 2008, and VMware, represents a special task for a server hardware.
All the hardware, such as network card, hard drive and processor, are provided by the server host and can be carried by virtual machines only with restriction in claim. The utilization of hardware must therefore be organized to carry out the virtual Machines to keep stable. If a server fails, all virtual machines that reside are eliminated. A good Hyper-V backup and VMware backup program for virtualization software can move due to its virtual machines on other servers. The versatility of a backup software program can serve also the cluster shared volumes (CSV) in Windows Server 2008 R2, a part of the failover clustering. In the event that a virtual machine should fall away, stepping in a different virtual machine for them.
This completely substituted the original virtual machine, because with the help of the server backup program all needed files already stored on this virtual PC. The raking in the execution of a backup can be divided with newer computer backups on multiple processors, so that multiple threads using multi core processors increase the overall performance entail editing. The multithreading, used makes possible simultaneous backups and makes them both quickly and easily out. A new achievement in backup programs is also the FTP server contained in the backup software that allows you to receive files over the Internet. The costs for required Web hosting because the files with the FTP backup world sure can be delivered on any PC as a remote backup. Despite the interruption of the Internet connection can builds using the already discussed deduplication at the site of the break. Especially for companies, programs are a means to reduce costs and also a good investment to the time it takes to reduce backup. Backup software programs are also by their versatile application and yet simple use for households of great benefit. A clever hedge because of the loss of that data could be expensive.
