[Borgbackup] recommended check option

[Boris Kirkorowicz]

Hi,
the backup job running since January has finished now.

I split the data to multiple repos. Two of the repos ended with rc=1:
> terminating with warning status, rc 1

I guess this is due to an interruption of the IP connect to the backup 
disks yesterday:

Now I wonder what is to do best. First thing might be

borg check /mnt/rs1219a/Boris

but there are some options mentioned in the docs that I do not 
understand, resp. their meaning. What is the recommended procedure here?
