Apple 2300 Series manual Backing up your files, Chapter

If a native program requires a shared library and there is not enough memory available for the shared library, you’ll see a message that the program could not be opened because of insufficient system memory. If this happens, see the “Memory” topic of Macintosh Guide, available in the Guide (h) menu, for instructions on turning on virtual memory.

If a required shared library is missing, you’ll see a message that the program could not be opened because the shared library could not be found. If this happens, follow the directions that came with your program to reinstall the program. If the shared library is still missing, contact the program’s manufacturer for assistance.

Backing up your files

Making backup copies of important files is good protection against possible damage to the originals.

mYour hard disk contains disk images of system software and the application programs that came with your computer. If you have an external floppy disk drive with an adapter or a dock, you can make disks from these images using the Floppy Disk Maker application program. (Instructions for using Floppy Disk Maker with a floppy disk drive are presented in the next section, “Making Software Disks.”)

mYou can back up an entire floppy disk by copying it to another floppy disk, or to a hard disk.

mYou can use a commercial backup program to copy new and changed files from a hard disk to another hard disk, to a tape drive, or to a series of floppy disks.

mIf your computer is on a network, you can back up files by copying them to a shared disk on the network.

mYou can back up files by copying them from one computer to the other using SCSI disk mode. (See “Using Your Macintosh PowerBook as a Hard Disk” in the “Connecting SCSI Devices” section in Chapter 3 for more information on SCSI disk mode.)
