Upgraded CPU and Mobo - now doin full backup

[Cralis]

I have a backup done onto an external; USB drive across a network. It's a 280gig backup and takes a few days due to speed. And since doing the initial backup, incremental backups nightly have been quick.

However, yesterday I replaced the motherboard and CPU on my machine.

Last night, it started a full backup, A new vbk file is being created. Why is this happening? It should be doing an incremental. Can I stop it, and tell it to use the old one?

Hi Craig,

VEB tracks the BIOS ID during backup. Once you changed the motherboard, your machine got a new BIOS ID forcing new full backup to be created. There is no way to map older backup in such case due hardware changes which may affect your bare metal recovery process.

Why would a backup program need to track the BIOS id?

[Dima P.]

To automatically preserve an owner and map the backup during recovery. Also because of the drivers, but I’ve mention that before.

How does all of that relate to the bios? Wouldn't that be me more along the lines of looking at disk signatures rather than BIOS signatures?

[Dima P.]

Disk signature is not good enough since it does not completely reflect hardware changed of your computer. By the way, if the motherboard was changed I also recommend to recreate the recovery media, so it has a new set of network and storage drivers included.
