Simple Explanation of Storage Policy & Subclient Policies?

[Mike00s10]

Hello, I am new to Commvault and just purchased 7.0 Galaxy Express Email & Server Edition last week from Dell. I have installed the CommCell and Clients without issue (other than having so many options on custom install to choose from). Where I get confused is what the difference/correlation is between the Storage Policies you can create and the subclient policies you can create. What I am wanting to do is fairly simply in theory but actually implementing it for the first time for me is confusing me. I have tested using the EZ configure wizard to create a recurring backup but I then am not able to modify or change that backup in any way it seems? Here is what I want to do:

- 1 Weekly System Backup (w/ system state) for all servers

- 1 Server backup job consisting of 6 50gb pre-allocated "message store" files Mon-Wed-Fri

-1 Server backup job consisting of 6 50gb pre-allocated "message store" files Tues-Thurs-Sat

Any help or clarification here would be greatly appreciated.

In short:

With Storage Policies you define where to backup up to (which 'Storage Resources' are used for backup and restore operations) and for how long you require to keep this backed up data restorable (the retention criteria).

With Schedule Policies you decide when to run which operation for which client and what type of data protection operation you want to use (full, incremental or differential). When using backup-to-disk-copy-to-tape operations we haven some more choi9ces but let's keep it simple.

With subclient you decide what to backup per machine (the 'content' of file systems and/or databases).

when you put them all together you have a data protection strategy.

Subclient policies are used when you have lots of machines that have exactly the same content, filters etc that are different from the 'default subclient'. I think you don't need this for your environment.

Thank you very much for that breakdown, that does help clear up some things for me a bit. I guess my next observation is that Galaxy Express does not have the "schedule policies" feature (it's something they deemed only necessary for Galaxy Enterprise I guess...). So if I understand what you have so kindly explained to me, I will want to create one storage policy for data that is retained for 2 weeks (file system/system state backups) and one other one for the message store data which only needs to be retained for 3 days, correct? I shouldn't need to deal with subclient policies from what I gather as well, so then I just need to go into each client and "add schedule" under the schedule feature when you right click on the "defaultbackupset"?

My other observation is with regards to the EZ backup wizard, it lays everything out nicely for you but once you've created a recurring backup policy for a client is where I get lost, it seems as if you are not able to modify those policies once they've been created...Am I just not looking in the right place after I have created a recurring backup with the EZ wizard?
