Microsoft backup program fails at 4 Gigabytes under Windows XP SP3

Initially I could not get the backup program to work at all, and then I ran regsvr32 ole32.dll which apparently reset the parameters to allow backup to run, however, when it reached 4 Gigabytes after a full system backup had been specified, the program stopped with the report results below this message.

The backup was going to a 400 GB WD Passport drive with 231 GB free space (formatted FAT32) from a 300 GB drive (ST3320613AS), 80 GB used/120 GB free (formatted NTFS).

Can the standard File Explorer backup program be used to backup the entire system with this configuration?

Any help or ideas are most welcome - especially before I have to go buy a program to do what seems like ought to be built in from the get-go...

  1. No brainer ...

    NTFS supports file sizes above 4GB ... FAT 32 does not.

    What you want is an external NTFS drive ... as your BU destination.

  2. Thanks Al, I'll reformat one of my USB drives to the NTFS and give it a go!
