One more question on best-practice for Backup Plan

I am not a SQL Server DBA, but have a temporary need to play that role. I am
new to the Maintenance Plan Wizard, but have thus far implemented the
following:
1. Daily System Full Backup Job (Selected System Databases)
1.1. Check Database Integrity
1.2. Rebuild Index
1.3. Update Statistics
1.4. Clean Up History
1.5. Backup Database (Full)
1.6. Runs daily at 6:15AM
2. Weekly User Full Backup Job (Selected All User Databases)
2.1. Check Database Integrity
2.2. Rebuild Index
3.3. Update Statistics
3.4. Clean Up History
3.5. Backup Database (Full)
3.6. Runs every Saturday at 6:15AM
3. Daily User Differential Backup Job (Selected All User Databases)
3.1. Check Database Integrity
3.2. Backup Database (Differential)
3.3. Runs Sun thru Fri at 6:15AM
4. Hourly User Log Backup Job (Selected All User Databases)
4.1. Backup Database (Transaction Log)
4.1. Runs Hourly Sun thru Sat at 6:00AM
This doesn't seem quite right to me. I am mostly confused by the additional
maintance options in the Wizard (Check Database Integrity, Shrink Database,
Reorganize Index, Rebuild Index, Update Statistics, Clean Up History, and
Execute SQL Server Agent Job). I am wondering if these should be included in
the full, differential, log backup jobs as I have done above or if they
should be run seperatly as one or more standalone jobs on some frequency. Is
there any info on best practices and/or examples on how to handle these
other job tasks?
It depends on the size of your databases and your backup window.
For example if you have several databases of only a few gigabytes each one
perhaps you can do full backups daily. If your databases are hundreds of
gigabytes the backup procedure you show make more sense.
Hope this helps,

Should they be run as standalone jobs... and how do I select which to run.
For example, reorganize index and rebuild index do not seem to be candidates
to run together in a single job and I have heard that it is probably ot a
good idea to run Shrink Database at all.

Do not shrink your databases in a job and avoid it even manually.
Do not run reorganize index and rebuild index together. Most important, do
you really need to reindex? Do you have a fragmentation problem? How big are
your databases? How big are your tables? Spent some time learning about dbcc
showcontig.
Hope this helps,

Now I am wondering about History Cleanup... does that clean all outdated
backup files from system and user?

It is up to you how much data you want to keep.

long since been purged. Around here, we keep our customers backups on disk
that are required to erstore from the last full backup, and everythingis on
tape for 31 days. Anything older than that is gone and purged in our jobs
using Sp_delete_backuphistory
