I had to abort a backup of my system because it stalled on the file /proc/kcore
. I check its size and, well, the file is enormous. Checking Google, it seems that many other people have absurdly large kcore files as well.
I have three questions:
- should I be concerned about kcore's size?
- if so, how can I reduce its size?
- is there any reason to backup the /proc/ directory?

First things first:
/proc
is a virtual filesystem. Do not back it up. Its contents do not exist on the disk.From
man 5 proc
:So, I'd be a bit concerned if the
kcore
is small.How do you reduce its size? Reduce your RAM.
