Replicating backups/cleaning up archives (1st location)' has completed with warnings.

First couple errors are because I stopped the backup. We have been getting replicating 'succeeded with errors' messages as long as I have worked at current place (couple years).

We had a ton that fail, and I have found numerous articles here with older versions stating a fix was released. Also saw that changing vault locations is a 'temp' fix...

I can find the other errors if need be, but this specific one is only a month old. The replicating step ran in secs all month, then yesterday took 6 hours. Today's ran for 7 hours before I stopped it. I need ideas here, I've read that some of these errors can be ignored, but I have seen backups than can't be recovered from due to this.

Thoughts??
