I run a backup everynight at 1:00 AM and in the morning I take that file and copy it to a CDROM for safe keeping. Well that backup file (Using XP Pro Backup Utility) has now exceeded the size of the CDROM 700 MB. (file size is 849MB and growing) Is there a way to back that file up to multiple CDROMS? Right now when I run the backup, I creat a file on the "C" Drive and in the morning copy it from "C" to the "E" CD/RW. First it creates a ISO file and in the morning I try to copy that file to a CDROM usinf XP's software, no special software. Any Ideas?
Thanks Rod

To the best of my knowledge, the only way to copy a file over multiple disks (CDs or floppies) is to either use a file splitting utility, or an archive utility that allows you to span disks.

I believe that the latest versions of both PK-Zip and Win-Zip include CD support.

A work-around would be to switch from a full backup to an incremental backup.
That way, the backup file would be a lot smaller.

You could also split the files into multiple sets, and run 2 or 3 backups to capture everything.
