So far I have burned four DVD's of the Desktop folder as of last night. I burned two of these DVD's on Kodak DVD's and two on Memorex DVD's. I also did this with four disks for the documents folder. All other folders than documents and desktop were considered two large for DVD back up.
I also used one external 250 LaCie USB hard drive to copy these two folders once. I also used my eMac and the LaCie back up software on the eMac to back up the user folder on the Macbook to a second LaCie 250 USB external drive attached to the eMac. These two computers are connected to a router in common which keeps them networked together.
Another step is still in progress and that is to use the LaCie backup software on the Macbook to back up many different folders like the systems folder, the users folder, the library, and the applications folder to a third smaller 160 GB LaCie USB external drive. So far backing up the applications folder this way has not worked so a copy of it was copied to the drive.
Windows XP is also installed on the Macbook so a copy of the major folders was made to the first USB external drive mentioned above and then this was copied to the third drive as well. Some Windows folders on the Macbook could not be copied due to permissions issues.
The last step will be to use the LaCie back up software to make one more copy of the user folder to the third drive. Then the backups will be considered completed.
