In this busy world, there appears to be a significant share of computer users who do not protect their system using backup software. By the same token, many home users are still unprotected from virus damage because they do not run an anti-virus program on their PC on their regular basis. The best protection against virus damage, however, is prevention: buy good data backup software and run it often!

Workstation backup has been practiced by most experienced computer users since the 1990s. The challenge with workstation backups is that data may need to be backed up while the user is working; hence, the backup tool needs to impact the system minimally, yet provide satisfying performance. In addition, another hurdle for backup software is that workstations are subject to frequent software installations and system configuration alterations.

Server administrators with extraordinary large amounts of information may want to look into the backup compression features of their backup software and vhd backup software. Compression usually ...
... works well on applications, text, PDF, word documents, system files, and other documents with a small noise ratio. Music and video generally do not compress well due to the nature of the information stored within.

IT gurus who wish to get their hands on a good server backup software package may want to focus on the file backup capabilities of their product. While a Windows backup may be necessary, it is usually more important to back up files quickly and reliably. The recent growth of Server Core and other installations of limited GUI operating systems may make data recovery plans more complicated since most backup tools do not support such environments. Managers would therefore want to check on their backup tool before planning a data center rollout.

Backing up volumes is critical on workstations since users rarely deploy file backup software to protect their data. Usually disk imaging is applied on an entire physical hard disk, but it can technically be applied to separate partitions as well, such as a single drive letter. The advantage of drive imaging is that it creates an exact byte-level copy of the information, including hidden file system information, such as residues of deleted files.

Virtual machine and virtual host backup is a different method of backup, such as the backup of a virtual machine in Microsoft Hyper-V Server 2008 R2. To back up a virtual machine while running, specialized virtual backup software is needed that generates a VHD backup that is crash consistent. A simple VM backup script is usually not adequate.

For a successful backup of Hyper-V Server 2008 R2, the backup tool needs to aware and custom-made to fit into the limited operating system landscape created by Microsoft. Because Core Installations are very limited in their operating system features, regular tools will not work and specialized Hyper-V backup software needs to be purchased.

In general terms, a virtual server backup software copies virtual server files and settings. To copy virtual machines, one needs to either take them offline from the virtual host server, or a dedicated backup software needs to be applied that works closely with the virtual host server system to access the underlying virtual disks.

As a newcomer, USB backup software has become very popular due to the proliferation of external hard disks. External hard drive backups are economic even to small and medium-sized companies because the cost per gigabyte is generally very low and the transfer speeds are phenomenal, especially with the recent innovation of USB 3.0.
To decrease the space required for backups, users often deploy a differential backup strategy, which compares the current state of a hard drive to that of the first backup run. A differential backup can also be restored relatively quickly because it is generally applied after the first backup has been restored.

The diminishing cost of Internet hosting and bandwidth has made FTP backup a feasible alternative to on-site backup. While FTP is supported by several backup products, specialized FTP backup software may be necessary for power users who work with a variety of files, such as international file names and files larger than 4 GB. FTP backups are probably not suited as general backup strategies because the cost per GB is still relatively high compared to that of USB and external hard drives.
