Backup being skipped

I have a SP that performs a Full backup once a week on Saturday and Differential backups the other six days. It works fine on three servers but is skipping a large DB on one server. No email is produced and no log is created. The DB that is being skipped is 260 gig. Here is the SP:

-- CREATE PROCEDURE Proc_Red_Gate_BackupDBs_Differential AS

-- ****************************************************************************
-- Query Name: BackupDBs_Red_Gate_Differential_PBIMGSVR.sql
--
-- Description:
-- This script is meant to run daily. It creates a cursor and loops through it
-- to create either a full backup or incremental backup of any/all databases on
-- a server. It will create a full backup one day per week and incremental
-- backups the other six days.
-- This script stores the backups in the following format:
-- dbname_type..sqb IE: BSADB00_Full..sqb -or- BSADB00_Diff..sqb

    Can you confirm that the large database is being picked up by the cursor? Possible problems include a name that is too large for the variable (varchar(50)) or a name that has unicode characters (need nvarchar(50)) instead.

    Does the backup start if you run it manually using the command generated by the script?

    Yes it does.

    If you cut/paste the backup command and create a standalone SQL Server Agent job to backup that single database, and start the job manually, does it run?
