——
You are architecting an HP StoreOnce Backup System solution for a customer with a primary and
a secondary data center on the same campus.
Backed up fileserver data should be replicated across data centers by VTL replication after a
backup is completed.
Customer gives you these sizing requirements:
Backup of one fileserver with 6 partitions, 150GB each
Daily full backup
Daily change rate by less 1% of the original data
Backup application is Data Protector 7.01
Retention time of 120 days should be achieved
Uni-directional replication between sites
Which HP StoreOnce Backup System is most cost effective and meets customer requirements?
A.
HP StoreOnce 2620 Backup System
B.
HP StoreOnce 4210 Backup System
C.
HP StoreOnce 4220 Backup System
D.
HP StoreOnce 4420 Backup System
Explanation:
6×150=0,9TB – first full bkp 1%x0,9*120 = 0,1TB total 1TB
The smallest model is SO2620i – 2,5TB usable
The count is wrong, because it’s needed to include the volume of first backup full, that will be 0,9tTB more, with a total of 1,98TB.
The option A still is the best option.
