You can have that same ext3 partition on SAN, using lvm.
On node1 it's active (volume group is activated), on other it is not.
If things fail on node1, you can activate the volume group on node2 and mount the filesystem.
You need to reconfigure your backup to take it from local disk, instead of NFS mount.
Do not have entries in /etc/fstab or scripts that activate / mount it automatically (that is what clusters are for.)
If you have clusterware, check if you can configure a simple disk resource for that disk/volume group.
Hope that helps

mount.nfs
MOUNT.NFS(8) System Manager's Manual MOUNT.NFS(8)
NAME
mount.nfs, mount.nfs4 - mount a Network File System
SYNOPSIS
mount.nfs remotetarget dir [-rvVwfnsh ] [-o options]
DESCRIPTION
mount.nfs is a part of nfs(5) utilities package, which provides NFS client functionality.
mount.nfs is meant to be used by the mount(8) command for mounting NFS shares. This subcommand, however, can also be used as a standalone
command with limited functionality.
remotetarget is a server share usually in the form of servername:/path/to/share. dir is the directory on which the file system is to be
mounted.
Under Linux 2.6.32 and later kernel versions, mount.nfs can mount all NFS file system versions. Under earlier Linux kernel versions,
mount.nfs4 must be used for mounting NFSv4 file systems while mount.nfs must be used for NFSv3 and v2.
OPTIONS
-r Mount file system readonly.
-v Be verbose.
-V Print version.
-w Mount file system read-write.
-f Fake mount. Don't actually call the mount system call.
-n Do not update /etc/mtab. By default, an entry is created in /etc/mtab for every mounted file system. Use this option to skip making
an entry.
-s Tolerate sloppy mount options rather than fail.
-h Print help message.
nfsoptions
Refer to nfs(5) or mount(8) manual pages.
NOTE
For further information please refer nfs(5) and mount(8) manual pages.

/etc/fstab file system table
