When configuring a weekly backup using xp_slsFastCompression, when the following parameter is specified:
@ElapsedDaysRequireFull = 7
The full backup is not created on the 7th day.
The logic is such that if the parameter is set as: @ElapsedDaysRequireFull = 7 , Litespeed will perform a full backup only if more than 7 days have passed since last full backup.
