Scheduling second item screws up existing schedule in Retrospect bug reports Posted June 26, 2012 · Report reply So, I thought I had figured out the new scheduling syntax, but alas...... I have a proactive script set to run M-F from 8 PM to 8 AM the next day....... SO WHY did it start running a backup at 445 PM? It is causing me much disruption and grief. I'm considering other incremental backup solutions even though I've been using Retrospect for many years.
