Back up most of what's on computer's terminal as a result of the recent cuts (4)
I believe the answer is:
scab
'a result of the recent cuts' is the definition.
I can't judge whether this definition defines the answer.
'back up most of what's on computer's terminal' is the wordplay.
'back up most of' becomes 'cab' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'what's on' says to put letters next to each other.
'terminal' indicates one should take the final letters (terminal refers to the end).
The last letter of 'computers' is 's'.
'cab' put after 's' is 'SCAB'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for scab that I've seen before include "Strikebreaker; mange" , "that blocks cut" , "Encrustation for the strikebreaker" , "Sign of skin wound" , "One regarded with contempt" .)
