/***************************************************************************
Purpose: To create a list of backups that are overdue.
Full, Differential and Log backups are considered.
An overdue status would be:
1a. Full Backup not taken for 24 hours where there is no Differential backup
1b. Full backup not taken for 7 days where there is has been Differential Backup within the last 24 hours
2. Differential backup not taken for the last 24 hours
3. Log backup not taken for the past 6 hours
This script will only work automatically for backup schemes that have performed at least one successful backup of each type required
This is an acceptable limitation, as when setting up/changing backups, one should manually check the first few cycles anyway
