# Fix Veeam Backups Next Run, a Veeam PowerShell script (Version 1)
# This script will properly set the Next Run schedule when entering a new day so that all jobs don't run between midnight and 1 am
# A Windows Task Scheduler must be configured to run this script on each Veeam Backup Repository server -- running at 11:55 pm each evening
# Run this on a Veeam Backup and Replication version 8 update 1 server
# You could even copy and paste it into Veeam Backup and Replication > Menu > PowerShell
