I personally run frequency with a clever schedule so i have failover
days incase full backups dont work at a weekend.
For eg. the weekly full schedule i set to run every 5 days, but with a
window of sat,sun and monday nights 10pm-8am. This means if backups fail
over the weekend i can see on monday, fix the problem then they run that
night. They automatically try 5 days later which is the following
saturday and are back in sync. A 7 day frequency would only try the
following monday.
On the other hand if backups work on the first saturday they try again 5
days later ( thursday ) but the window doesnt allow them to run, so they
keep trying until saturday which is normal running day for full backups.
See below if any help.
