Bit of an oddity this one.
Three PCs in our home, each with online back-up problems. We either get a message saying have a server error 8707,536872940 that's asking us to try again later, or, it detects files to be backed-up and transfers approx 90%, then does nothing.
I'm preseuming this a temporary thing and will pass.
However, what we have noticed is that the system overlays (blue arows/green ticks) are back to blue arrows. One PC that just recently had every document backed-up (having green ticks) and has not had its documents altered now has the blue arrows. When the 360 scans for files to be backed up it is basically suggesting they all have 're-saved'. I've checked just how much of my online 25gb space has been used and it's still saying 23gb, just as it's always been, so I know it has all my documents stored online.
I've explained this problem the best I can.
Any ideas anyone?
