Backup strategy best practice please.

Dear Experts,

I am running new tape library for my company data backup I need advice for best performance backup for system states and backup of users data and servers db (sql,oracle)

I found it some complex with BE for how I could do it in concepts like overwrite protection period and appended period.

I was using stratigy of :

for DB (sql + Oracle+exchage server DB ) and Users Files/folders

1) every day incremental backup data

2) every friday full backup data

for system state:

1) full backup at the end of each month.

these days I am working to configure the backup on Symantec BE2014 with tapes so,How Could I do ?what is the recommended OPP and AP for my stratigy? what is the steps for configuring the storage pools as I am doing this maually ( I dont activate barcode)? what is the partitions and how i could use it?

I will be clear with you I am new with configuring Tape library so,please guide me for the main ways to make it working correctly.

Thanks in advance.
