I remember that for a disaster recovery kit I would periodically backup (find|cpio) just the root filesystem (in maintenance mode) and then store that tape with the boot&root set in the safe. If the root filesystem became damaged and the system unable to boot then I would use the boot&root and then:
to restore the root filesystem. (perhaps also need to re-write the MBR)
Once system was booted I could sort the other filesystems.
Only then, with non-root filesystems mounted, would I use last nights backup tape to restore the whole system (which would include the very latest root filesystem (which would overwrite).

mkbootdisk
MKBOOTDISK(8) System Manager's Manual MKBOOTDISK(8)NAME
mkbootdisk - creates a stand-alone boot floppy for the running system
SYNOPSIS
mkbootdisk [--version] [--noprompt] [--verbose]
[--device devicefile] [--size size]
[--kernelargs <args>] [--iso] kernel
DESCRIPTION
mkbootdisk creates a boot floppy appropriate for the running system. The boot disk is entirely self-contained, and includes an initial
ramdisk image which loads any necessary SCSI modules for the system. The created boot disk looks for the root filesystem on the device sug-
gested by /etc/fstab. The only required argument is the kernel version to put onto the boot floppy.
OPTIONS --device devicefile
The boot image is created on devicefile. If --device is not specified, /dev/fd0 is used. If devicefile does not exist mkinitrd cre-
ates a 1.44Mb floppy image using devicefile as the filename.
--noprompt
Normally, mkbootdisk instructs the user to insert a floppy and waits for confirmation before continuing. If --noprompt is specified,
no prompt is displayed.
--verbose
Instructs mkbootdisk to talk about what it's doing as it's doing it. Normally, there is no output from mkbootdisk.
--iso Instructs mkbootdisk to make a bootable ISO image as devicefile.
--version
Displays the version of mkbootdisk and exits.
--kernelargs args
Adds args to the arguments appended on the kernel command line. If this is not specified mkbootdisk uses grubby to parse the argu-
ments for the default kernel from grub.conf, if possible.
--size size
Uses ize (in kilobytes) as the size of the image to use for the boot disk. If this is not specified, mkbootdisk will assume a stan-
dard 1.44Mb floppy device.
