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. Specifically for files of the operating system and software, which are not only large, but often little change, it helps delta compression space and hard disk drives as profitable to use. This includes also software virtualization, used especially in farms in claim. The virtualization platform draws the specified hardware completely, by They virtual machines (VM)!SPIN!SPIN provides.

Delta encoding helps in this case specifically to reduce space and hence hardware, as well as the enormous costs involved. A virtualization platform, such as for example, Hyper-V for Windows Server 2008, and VMware, represents a special challenge for a server hardware. All the hardware, such as network card, drive and CPUs, are provided by the server host and can be used only to a limited extent by virtual machines. Thus, the workload of the hardware must be coordinated to keep the performance of virtual machines at a high level. If a server is down, all virtual machines that are on it are eliminated.

A powerful Hyper-V backup program and VMware backup program software virtualization can transfer consequently virtual machines on other servers. The varied use of a backup program can be conducive also the cluster shared volumes (CSV) in Windows Server 2008 R2, a feature of failover clustering. If a virtual machine should fail, stepping in a different virtual machine for the former. It replaced the first virtual machine fully, because on the basis of the server backup software all required files were backed up, now on this virtual machine. Utilization of processors at a backup can be, distributed with effective PC backups on multiple processors, thus multiple threads using modern processors the editing has the increase in the overall performance. The multithreading used makes possible simultaneous backups and carries out both quickly and consistently. The remote data backup is new in FTP server backup software contained therein. Backups can run elsewhere wide web live, but nonetheless surely, by receiving from a hard disk on the world. Can be omitted in this way with a Web hosting FTP backup, which you in turn can save money. The de-duplication provides this, that the FTP backup regardless of disconnection unmolested at the discontinuous point keep as soon as the Internet connection is restored. In particular for enterprises are a means to cost to reduce backup software and to reduce even a good investment to time. Backup software programs are, not least through their versatile application and yet simple use for households extremely helpful. A secure retirement because of the loss of that data could be priceless.
