Yes, but it's not a deal-killer:  seeing as it's been running for years as-is, it'll be fine.  I thought it was a new configuration and you did that.  I'm with you:  if it ain't broke, don't fix it.  In this case, it's slightly broken, but not terribly.  It affects performance more than anything.

What is happening is that the nightly process (which deletes old backups, among other things) is runnning at the same time as your backup.  That causes the hard drive to thrash, and the backup will take longer (rather noticeably longer, depending on the size of your pool).  Obviously not the end of the world, but not recommended.

Given that change, if and when you create a *new* BackupPC server, you might not want to blindly use your current configuration.  The previous person seems to either liked to make configuration changes for the fun of it (or when they didn't really understand what they were doing), or didn't mind making big changes to solve smaller problems.  Either way, that's probably not a configuration you want to swallow without looking.
