Booting from a tape is generally not supported in PC hardware. A basic tape drive cannot do it: you need a tape drive that has special support for booting a PC from a tape. It is done by having the tape drive emulate a CD-ROM/DVD to make the PC boot a restore program, then the program restores the rest of the tape content as normal. The boot tape must have a special structure, and only some backup programs can create a bootable tape.

You would be then tied to this specific technology: as there is no real standard for booting a PC from tape, different manufacturers' solutions might not be compatible with each other.

HP's technology for this is called One-Button Disaster Recovery (OBDR):

It might be easier to re-arrange your filesystem layout so that your root filesystem (including your standard backup software) fits into a single bootable backup DVD. Restoring that would give you enough functionality to restore the rest of the system from multiple non-bootable DVDs, if necessary.

I would highly suggest Mondo Rescue. It can span your system image across multiple ISO files/images. You can store them anywhere (tape, NFS share, CDs, etc), and then restore the system from them. I did a bare metal restore over NFS last week, smooth as silk.

I forgot to mention that the restore process is handled from a bootable CD. You then tell it where to pull the ISO images from (tape, NFS share, CDs, etc). This is a much more compatible method for PC-style hardware.
