Full, diff and tlog backups based on recovery mode

,

    This a script which creates stored procedures that can be executed adhoc or set as sql agent jobs to check the recovery status and generate full, differential or transaction log backupf for each database if the database recovery status is set to full.  We have terabytes of data and set all production databases to full and all test and demo databases to simple. This helps to ensure all our production databases are backed up while avoiding unnecessary backups.
    The full and transaction log backup call the sqlmaint utility which simplifies deleting old backups by setting the -delbkup parameter. The differential backup includes an extra vbscript component to delete old backups as you cannot use the sqlmaint utility.
    Complete instructions are in the script so please read and follow carefully. Feel free to email me with any questions. When you get to the visual basic script portion, check the format as unlike SQL, all code must be on the same line or use the ampersand, followed by a space and then the underscore keystroke & _ after each line to continue to the next. My thanks to Mr. Knight as I used his book "SQL Server 2000 for Experienced DBAs" for reference when building components of this script.

/*to implement:
    A-execute sql script to create three stored procedures, usp_fullbackups, usp_diffBackup and
      usp_Tlogbackup.
    B-create visual basic script file by following instructions in VBScript section.
    C-Change all 5 paths in marked areas
        Path change 1, change -BkupDB path to location of full backups
        Path change 2, change this path to point to location of diffBackupFileDelete.VBS
        Path change 3, change path to location of differential backups
        Path change 4, change Path next to -BkUpLog to location of transaction log backups
        Path change 5, change path to physical location of vbscript file
    D-Change length of times to keep full, differential or transaction log backus where marked
        Change retention date 1 next to -DelBkups i.e. 2days, 2weeks, etc.
        Change retention date 2 next to -DelBkups i.e. 2days, 2weeks, etc.
        Change retention date 3, change number to subtract from now date
                i.e. 1 to delete after 1day, etc
    E-In SQL Agent, create and enable following jobs
        1.Full Backups, step one type command: exec dbo.usp_fullbackups
        2.Differential backups, step one type command: exec dbo.usp_diffBackup
        3.Transaction Log Backups, step one type command: exec dbo.usp_tlogBackup. 
        Set each job to run according to policy (e.g. full backups weekly, differential daily,
        and tlogs hourly around full and differential times). 
    F- monitor jobs to ensure they execute and check for sufficient disk space.    
    G-also ensure that sql server and agent accounts have sufficient access to backup and vb script 
      directory.
