Backup software: Features explained
Supported media
Rather than use CDs, it is often quicker to back up onto a memory stick
Not every backup program will support every storage medium. Suprisingly, some don't even support CDs or DVDs. Commonly supported types are floppy disk, network (or Internet) drive, hard disk, USB memory stick, CD-R, CD-RW, DVD-R/W, DVD+R/W.
Maximum file size
Whereas most software will back up the vast majority of files, some might choke on multi Megabyte or even Gigabyte files. Before you buy, make sure you know the maximum size (and then some) of the files that you intend to back up (such as videos) and ensure that the software supports it.
Support options
Putting confidential files on a disk makes it easier for thieves
Typically, software will offer Help files, online FAQ , forums and webforms. Of course, if you have just seen your life's work disappear from your computer, you may not feel inclined to wait for a return email if your back up software refuses to play ball. Telephone support and a calm voice is often much more preferable.
Verification
The software can double check that it is saving the data accurately as it goes along. It's no good finding out after the event that the data files were corrupted.
Encryption
Encryption may be important to you if you are backing up sensitive data. By backing up unencrypted data onto a handy CD, you are making it much easier for a thief to steal your secrets
