JSI Tip 3875. NTBACKUP issues insufficient disk space error when you backup to a file?

When you backup to a file, you receive:

Insufficient disk space exits to continue the current operation. Please free some disk space and retry the operation.

If the destination file is located on a FAT32 partition, and you are backing up more than 4 gigabytes of data, you will receive this error.

Either create multiple backup jobs or convert to NTFS.
