It can run while backuppc is running though it will obviously miss
some new files added by backuppc after you started running the
program. My routine is non-destructive (it doesn't 'fix' anything) so
it shouldn't conflict.

I don't think i understand the question...

Look at the usage info ;)
Or if you trust it to detect and fix it all in one step:
   BackupPC_fixLinks.pl -f [> optional output file to capture all the
   detections and status's]

Or to do it sequentially:
   Detect:
   BackupPC_fixlinks.pl  > [output file]
   Fix:
   BackupPC_fixlinks.pl  -l [output file]
