Data compression. Any backup software worth its salt will be able to compress your data so it doesn"t take up too much space on the final storage medium. Savings can be significant. Some packages even allow you to alter the compression values. In general, higher compression rates mean the backups take more time to perform so, if compression settings can be altered, you can decide for yourself what your preferred time\compression trade-off is.
- Encryption. Backup software should allow you to encrypt your data. Some of it could be personal or commercially sensitive. Whether you"re backing up to an external storage medium, or elsewhere on the network, when you create copies of your data you multiply the chances of it falling into the wrong hands. Encryption is essential to making it secure.
- It should be capable of performing incremental backups, meaning that only files which have changed are actually backed up. Without this feature, you"d have to manually sort out old and new files or just copy everything every time you did a backup, of course taking up a great deal of time as you did so.
- Scheduling. Nearly all backup software will allow you to set schedules in advance. That way, backups can be done automatically at a time that"s convenient for you.
- Handling open files. If you"re working with important data on your PC continuously and want that data to be backed up dynamically as it"s being changed.
- Controlling CPU usage. Backing up data can sometimes be processor-intensive, interfering with other tasks you want to perform on your PC. Some backup software allows you to throttle the demands it will make on the CPU"s resources, allowing you to get on with your work while the backup is performed unobtrusively in the background.
- Help handling special files. For example, let"s say you want to back up your the bookmarks in your browser or your repository of emails. They exist as files on your hard drive but do you know where they are? If you do, good for you, but not everyone does. Backup software often comes with built-in procedures for locating and backing up these special kinds of file.
- File Filtering. Almost all backup software will come with some kind of file filtering mechanism that makes it easy to include or exclude specific types of files when you do a backup. For example, let"s say you want to include every Microsoft Word or RTF file in your C: directory, or you want to backup everything on your H: drive except mp3 files. With backup software, it"s very easy to do this; without it, you"d have to do a cumbersome search and copy operation every time.
- Disc spanning. If you have a lot of data to backup, it probably isn"t going to fit on a single blank disc. You can try and save it all in little chunks which you arrange in advance to be no larger than the media you have available, but wouldn"t it be nice to have jobs of any size chunked up for you, allowing you to spread them across a number of discs. That"s what disc-spanning is. Some software will even allow you to make use of multiple drives if you have them. That way, you insert a blank disc into each one, and the software moves to each of them successively as the previous one fills up. It cuts out the need to actively monitor the progress of each backup job, allowing the backup to be completed automatically while you turn your attention elsewhere.
- Disaster Handling. Many backup packages allow you to prepare for extreme situations, such as those where your computer is unbootable or where you cannot access it directly. Some offer the option of creating an emergency boot disc that will restore your computer"s essential functions as well as any data you have saved. Another common option is to allow you to save your data as an executable file. That way, you can restore it with just a single click, whether or not you have the backup software installed, even from a remote location.
Backups for your data are very important. Many people will say thins from their own experience. Personal computers have many chances of crashing and this failure is sometimes unacceptable. There are any people that have important and sensitive data and they keep it on their computers without creating backups. If the computer crashes they may not be able to salvage that data and this means irrecoverable data loss.
But you can avoid all that trouble if you do a backup for your data. You need to use a software and there are many solutions to choose from. If you have a lot of data that needs to have a backup, you can try to backup it once a month, once a day or by the hour. It depends on the volume of data that you have and also on the importance. There are many types of backup to choose from: the full backup will create backups for all the file sin your computer, the incremental backup only saves the chances to those files, the unattended backup is enabling you to take place at a certain hour or day, the archive or disk image will make backups for files that are on the disk, the differential backup will create backup for the files that have been changed files and the final one is the snapshot backup.
Backups can be placed on many devices like CDs, DVDs, floppy disks, printouts, tapes, removable hard disks, online servers, and much more. They can also be included into fixed media. If you want to reduce the risks of loosing data then you need to create multiple backups.
Also, when you are buying a backup software tool you need to consider factors like: the ease of operation, the ability to do backups without monitoring, that you can handle different backup formats and also the capacity to restore without errors.
Some of the most used software tools are: Handy Backup, Double Image, ABC Backup, Genie Backup Manager, NTI BackupNow!, Novastor NovaBackup, Absolute Backup, Active Backup Expert, Advanced Backup, Avail Solutions, BackRex Backup, Backup Buddy, Data Sheriff, AKG Backup, Argentum Software, Disk2disk and others.
