How do you create a back-up copy of a file in DOS?

• A. By using the COPY command
• B. By using the BACKUP command
• C. By using the REPLICA command
• D. By using the CLONE command

Answer: (A)

Creating a backup copy of a file in DOS is commonly accomplished using the COPY command. This command is designed to duplicate files from one location to another, effectively allowing users to create a backup. When using the COPY command, you can specify the source file and the destination path, which facilitates the process of making an exact copy of the file you wish to back up. The BACKUP command, while it may sound relevant, is not a standard command used specifically for backing up individual files; it is more related to backing up entire directories or drives, which might not suit the needs of someone looking to back up a specific file. The REPLICA and CLONE commands do not exist in DOS as standard commands, which means they wouldn't be functional options for this task. In summary, the COPY command is the correct approach for creating a backup of a specific file within DOS, allowing users to safely duplicate their important data.
