In short, SLPs will manage and automate duplications. It guarantees duplication in the sense that it keeps on trying until successful, while the retention of source copy is set to Infinity until duplication has completed successfully. 
Once SLPs have been configured for backup and duplication, you select an SLP as backup storage in your policy or in the schedule.
If different retentions are needed for daily, weekly, monthly, etc, you need to create different SLPs and select it in the relevant schedule.

Lot more information in NBU Admin Guide I in chapter 14: Configuring storage lifecycle policies

Are we supposed to do SLP"s for all the clients in particular master server/enviroment or is it client demand specific.

I would say yes, its a client demand config.

SLPs are mostly used to manage backup to disk and then duplicate to tape.

Not all companies backup all clients to disk (Advanced or Dedupe). The requirement may be for a handful of critical clients to be backed up this way and the rest directly to tape.
So only the critical client policies will use SLP, the rest normal Media Manager STU in policies.

"Are we supposed to do SLP"s for all the clients in particular master server/enviroment or is it client demand specific."

You're not supposed to do it for any, unless the backup environment was designed to run SLP.

Many people add SLP on as an after thought, without correctly sizing the system to run SLP.  THis means the system is busy 24/7 wioth only just enough time to run the backups, duplications , before the next days backups start ...

This is fine until there is some downtime ....

The issue is then that as the system is busy 24/7, there is no time to catuch up on missed backups / duplication, and sudden;y this is a major major issue.
