[Borgbackup] speeding up borg check

I've read the docs on borg check 3 times and I'm still lost :-(... It 
says in detail what --archives-only and --repository-only do, but I 
don't know what that means...

I'm backing up a ~1TB filesystem daily where almost nothing changes and 
I want to run a prune and a check after the create. The check currently 
takes 11 hours (slow disk & cpu). Ideally, what I'd like is for check to 
do the maximum number of verifications short of reading the whole TB. So 
check any indexes, directories, presence of files, etc. Just don't read 
the full TB to verify each bit, I'd do that explicitly once a week or 
once a month. Is this possible?

Thanks!
