Methods for Backup

Backup should be an essential part of your computer experience for computer users. Users have been alarmed to backup their data for there are many stories of people who have lost all the data due to system crashes, malware, natural disaster or viruses. Although there are possibilities to recover your files after a disaster, it will not assure to get your data back and your important data is still at risk. It is far easier and safer to restore your files from backup rather than to attempt to recover data from your crashed computer.

Data backup is easy to do and can save you a lot of time as well as ensure the security of the data. When you back up your files, you are storing your files separately from your computer. In this way, even your computer crashes, you still have a way to access to your files where you back up it.

It's not only mission-critical business information that should be backed up. The data on your home PC needs to be backed up as well. There are three methods of backup: traditional backup, image backup, and continuous. No matter what method you're most comfortable with, please keep in mind to back up your important data to avoid important data loss.

Traditional Backup

Traditional backup (also called file-based backup) programs read and write data at the file level, and are the oldest type of backup available. The biggest distinctions between products lie in their ability to back up open files (files being edited by apps, or locked by the operating system), support for professional hardware such as tape drives, and disaster recovery--namely, the ability to boot from a CD and restore the system as well as data. EaseUS Disk Copy is a free backup tool for this method. By creating a bootable CD, it can provide sector-by-sector disk/partition clone regardless of your operating system, file systems and partition scheme. The sector-by-sector method assures you a copy 100% identity to the original.

Backups Based on Imaging

"Imaging" is the copying of the entire contents of a hard-drive partition--the boot sector, operating system, and data--to a single file. The beauty of an image is that creating or restoring one takes only a single step--backup and disaster recovery just don't get any easier. That said, the line between traditional-backup programs and imaging apps is blurring. Some programs have been released to have the ability of backing up individual files and folders in addition to full partitions, and can even perform incremental, such as Norton Save & Restore and Acronis True Image.

Continuous Backup

Continuous data protection (CDP), sometimes called real-time backup, tracks files and backs them up whenever they change. Think of it as something like selective RAID mirroring, where only the files and folders you choose are copied. Unfortunately, CDP suffers the same weakness as RAID mirroring does: It might back up corrupted and infected files, as well as pieces of malware. The risk is substantially reduced, however, since nearly all CDP programs let you keep multiple versions of the files you back up, and normally you'll be backing up only data, not the executables that are most prone to attack. All told, CDP may cost you a few CPU cycles here and there, but it's a great way to keep your system backed up at all times. Programs, such as NIT Shadow 3, IBM Tivoli Continuous Data Protection for Files and StarDock KeepSafe can do a continuous backup.
