Make ADF of Amiga partitions

[Oldsmobile_Mike]

Why not just use a regular backup utility to back up the entire partition?

These other guys have it right. Back in the day Amiga's occasionally came with backup utilities. There was ABackup that I think came with 3.1, or Quarterback Tools, or some various utilities on Aminet that I forget the names of, etc. But honestly when I want to make a backup of my Amiga drives now, I just pop in a spare CF or SD card and use DirWork or Directory Opus or somesuch directory utility to make a copy of all the files onto the blank drive. If you have an A1200 you can backup your main drive onto a CF card in the PCMCIA port.  Easy!

Like Obi-wan said, "ADF is not the file format you're looking for."    Just clone the partition onto a separate device.  Done.

But i did not know if i can fit all my files into a big ADF image file for the 3 partitions, or are they fix size of a floppy disk?

Seriously, forget about ADF.  It's a disk image.  Floppy disk only.  I think they can go up to 1.76MB, for Amiga HD disks.  You can't make an ADF of an entire hard drive.  If you did it would be dozens, or hundreds of megabytes.  It's not like .zip on a PC, it's a fixed file size format for a specific purpose (floppy disks).  If you did want to make a single, big archive of your Amiga hard disk, you'd probably want to use LHA, or one of the Amiga archiving utilities.  But not ADF.
