One making a pickle of things before connecting computer? (9)

I believe the answer is:

preserver

I'm a little stuck... Click here to teach me more about this clue!

'one making a pickle of' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.

'before connecting computer?' is the wordplay.
'before' becomes 'pre' (prefix meaning 'before').
'connecting computer?' becomes 'server' (I am not sure about the 'connecting' bit.).
'pre'+'server'='PRESERVER'

'things' acts as a link.

Can you help me to learn more?

(Other definitions for preserver that I've seen before include "Museum curator maybe" , "Keeper" .)
