Hi,

I've purchased an external USB hard drive for back up purposes. However,
when the back up reaches 4GB it fails.

Any idea how I can rectify this problem?

Your external harddisk is FAT32 formatted. And for good reason:
that makes the drive readable by most systems.
One of FAT32's limitations reads: max filesize = 4 GB.

You should take a moment and contemplate what you are gonna do
with 4GB+ 'backup' files. Loose a single bit anywhere within such
a file and you loose the entire backup :-)

Have your backup program create chuncks of --say-- 675 MB.
That way, they are far more managable. And --if you whish-- you
can burn them on CDR or DVD.

Just to add a little bit to Gerard's precise statement............
Your alternative is :format your external hdd in NTFS.

More detail is needed.

Filesystem of HDD, and the backup method/program. Some
allow specifying smaller split files instead of one giant
file.

All 8 of my USB hard drives (4x 500GB, 1x 400GB, 3x 160GB) are formatted
with reiserfs. I use rsync to make backups.

As OP posted using MS Outlook Express I doubt if you will make
him happy, advising reiserFS :-)

Part of the point is, "not FAT32". That might support the notion that he
could use NTFS. Other options include having everything on a file server,
which is how I access those drives from MS Windows, when I might need to.

"the backup". Yeah, that's a detailed or accurate description of WHAT
program you are using to create the backup ... not! Some backup
programs are nothing but a GUI attached to a copy program, some of
which merely shove the files into a .zip file. Some archiving
libraries are antiquated and only allow the creation of 4GB maximum
sized .zip files. Some deficient or crippled backup programs will not
span a backup across multiple files. If you are hitting the FAT32
filesize limit of 4GB, and if the backup program won't span the backup
across multiple backup files then use a better backup program.
