configuration backup is very large and contains netboot

Hi all,

I noticed that on one node of a cluster (Ontap 9.7), the system configuration backup was much larger than on others (1.5Gb instead of the normal 50Mb on the other nodes). I see that the complete netboot directory is contained in this backup (1.4Gb in size). How can I exclude this directory from the configuratioon backup or can I even just delete it in the root volume ?

Every time the configuration backup is taken, I get slow CP warnings for my root aggregate, so I would like to ease the stress by shrinking the config backup.

There used to be a KB describing this I think, but it seems to have disappeared. It was called  'How to find what is filling a node's root volume'

Thanks is advance

Grtz,

Tom
