Cl The BACKUP command can perform incremental backups. That is, you can copy only those files that changed since the last time you used the BACKUP command. This also results in more efficient diskette use.

Ci The BACKUP command can format new diskettes as it copies files. You don’t have to go through a separate formatting step when you use BACKUP.

Unlike DISKCOPY and COPY, which make readable copies of files, BACKUP creates files that you cannot use until you restore them to the disk by using the RESTORE command.

You can use switches with BACKUP to back up files created after a certain date or to specify files stored in a certain directory. You can also tell BACKUP to add only those files that were modified since the last time you ran BACKUP. This process speeds up the backup procedures you perform on a regular basis.

For complete instructions on the use of BACKUP and RESTORE, see your MS-DOS Reference Manual.
