Sorry about throwing this pile of info at you. I'm a bit short on time
right now. But in the follow pasted info, you'll find your answers.
I'll leave you the task of trimming it down.

2.18. How do I split a compressed backup into smaller files onto another
hard disk?
This type of backup is typically done by those who want to split the
archive into smaller chunks to fit on a CDR or to avoid the 2GB file size
limitation. To do this type of backup you will need Dylan's boot disk,
your original A drive to backup and a DOS FAT formatted hard drive to put
the backup on. The drive needs to have enough space to hold the backup.
It should be noted that if your TiVo has been used much the backup will
be exceedingly large and doing a disk to disk image is generally a better
idea. If the A drive is from a virgin TiVo this compressed image could be
anywhere from 600MB to 20GB. The size will vary even for virgin TiVo's
because some have the store demo mode on them and some don't. For the
example below we will assume the following drive connections.
Original A drive connected to secondary port as the master drive (
/dev/hdc )
DOS/Windows formatted drive connected to Primary port as the master
drive ( /dev/hda ). The partition can be either a FAT16 or FAT32
partition. Dylan's bootdisk does support Ext2 partitions also if
you wish to use one.
Do not connect the DOS/Windows drive to anything but Primary master.
Byte swapping is used for all other devices and Linux will not be
able to mount DOS partition connected to them.
The following are the steps needed to do the backup.
1.Connect the drives as stated above
2.Boot the computer with Dylan's boot disk in the floppy drive
3.Login in as root
4.Type mount -t vfat /dev/hda1 /mnt (no quotes)
5.Type dd if=/dev/hdc bs=32k | gzip -9c | split -b 650m -
/mnt/tivodisk_ (no quotes).
Use dd conv=noerror,sync if=/dev/hdc bs=32k | gzip -9c | split -b
650m - /mnt/tivodisk_ (no quotes)
instead, if the first command gives you an error.
6.In the step above 650m denotes 650 Megabytes. This size file
should fit on a CD later for burning. You can make this value
whatever best suits your needs.
7.Go relax because this will take awhile. Depending on the speed of
the computer, size of the A drive, this could take anywhere from
3 to 24 hours!
8.When finished make sure there were no errors.
9.Type umount /mnt (no quotes)
10.Power down the PC.
To restore the backup do the following. Remember that this will erase
whatever is on the drive connected to the secondary master port.
1.Connect the drives as stated above
2.Boot the computer with Dylan's boot disk in the floppy drive
3.Login in as root
4.Type mount -t vfat /dev/hda1 /mnt (no quotes)
5.Type cat /mnt/tivodisk* | gzip -dc | dd of=/dev/hdc obs=32k (no
quotes)
6.Go relax because this will take awhile. Depending on the speed of
the computer, size of the A drive, this could take anywhere from
3 to 24 hours!
7.Make sure there were no errors reported
8.Type umount /mnt (no quotes)
9.Power down the PC

splitting up a file on floppys:
hi all.
it seem i remember that somehow linux can split files up on floppys, can
someone give me a hint as to what command i would use to do this. do i
use
TAR to do this (as one would do with PKZIP in windoze)? or is there
another
command.
thanks much.
also, this is my first post from AOhelL. if it is in HTML format please
yell
at me so i can fix it. thanks
