from Apple doc:
Your first Time Machine backup will be several gigabytes because it includes all files on your computer. It could take overnight, or longer, depending on how much data you have. Once the initial backup is complete, all subsequent backups are incremental.
It is recommended that you do not interrupt the first backup.
If the first backup is interrupted, when you resume, Time Machine verifies the integrity of the first partial backup. This takes some time and during this period the backup appears to progress very slowly. This is normal and your backup will resume once the integrity check is complete.
If you have an Ethernet cable, you can perform your first backup to your Time Capsule via Ethernet; this will allow for the fastest initial backup especially with client computers that use 802.11b or 802.11g.
If an interruption occurs, Time Machine will wait for a period of time to see if the Time Capsule becomes available again. After this time expires you will see a alert message stating "Time Machine Error. Unable to complete backup. An error occurred while copying files to the backup volume." In Time Machine preferences, the "Latest Backup:" field will state "Failed".
If this alert appears: "The storage location for Time Machine backups can't be found," open Time Machine preferences or click its icon in the Dock. Reselect your backup storage location.MacPro 2.66 mhz Dual-Core Xeon 2 terabytes of HD, Mac OS X (10.5.2), MBP C2D, iMac C2D, PB G4
Thanks for the reply. I had already been through that part of the loop.
Last night went to my local apple store and changed the Time Capsule.
I managed my first successful backup overnight. So far everything looks great and I think that it clearly points to a H/W problem in my previous unit.

I'm having exactly the same issue with my 15" MacBook Pro. It will get several gigabytes into the backup and then I'll get the error message "Unable to complete backup. An error occurred while copying files to the backup volume". I've started/re-started the backup multiple times, tried doing it wireless and via ethernet all with no luck. On the other hand, my wife's 20" iMac completed the backup successfully the first time. I'm beginning to believe the problem is with my MacBook Pro and not the TC itself.
The backup has now bloated to over 100GB out of a possible 200GB due to restarting each time. I've gone so far as to delete the previous backup attempts and even erasing the drive completely.
I'm at a loss as to what could be interrupting my backups that didn't affect mywife's iMac.

This sound like a different issue to that which I ran into.
From the your post, it doesn't sound like you're deleting the partial back ups. I'd recommend that you do that and try and start with as clean a slate as possible.
On a first pass, try deleting your partial backups. If that still has problems, I'd be inclined to sacrifice your wife's backup to get the TC back to it's original system. Then start with backing up only your machine.
I also presume that you're doing both of your initial backups using an Ethernet cable.macbook pro, Mac OS X (10.5.2)
