Spb Backup question?

[gemilove]

Can somebody help me what to do when, w/ this Spb Backup?
a) Normal Mode b) ROM Upgrade Mode or c) Device Upgrade Mode? (Overwrite existing files - check or not?)

==>Also In Customize Restore, PIM Data, Emails, Text Messages, My Documents, and System Data? If choose "restore registry" wouldn't it mess up the newly upgraded rom's registry? (maybe a newb's question, but)

for example,

Full backup in: when restoring to: Upgrade Mode

1) Juicy's Rom 3.1 Juicy's Rom 3.2 a, b, c ?
2) juicy's Rom 3.1 Jugalo's Rom .5 a, b, c ?
3) juicy's Rom 3.1 Juicy's Rom 3.1 a, b, c ?
(HTC Touch) (HTC Diamond)

I know it may look a little confusing, but if u know this program, then i'm sure u know exactly what i'm asking... Thank u very much in advance!
