What is the difference between copy and backup?
Copy is an exact duplicate of the file whereas a backup image is a compressed image of the file which has a certain extension depending of the particular backup utility.
Reply:i think these two have the same kind of meaning,but with backup we can store the data for future usage, so that we store it in CD,DVD,usb drive,floppy .but with copy with in a computer we can copy from one drive to another drive.
Reply:A copy is just that - an exact copy in a different directory on the hard drive or on an external device for safe keeping.





A backup can be either an exact copy - usually on an external location for safe keeping, or, if you choose in Tools, Options, it can be a copy of your file up to the last save. This option can come in handy if you have ever accidentally deleted a file or messed it up royally. If you open the backup (which is read only) you can save it to a new name and at least have your work up to the last save. This option has saved my bacon a couple of times.
Reply:Well, basically, they have the same objective or concept..


To have copy of a file. But in a technical aspect, the "copy" command copies the file itself as is. The term "backup" nowadays may mean the file copy is either encrypted or protected for safe recovey and is stored in another location or media different from the original file.
