Most businesses typically backup and replicate their entire footprint, and the costs can be
about 3 times the cost of primary storage.
For example, if you have 1PB of source data on primary storage, you are paying for:
- 1PB Replication/Mirror – Storage at the same cost as your primary storage
- 3PB Backup Storage – Typically businesses have about 3 to 5 backup copies
- 1PB Backup Software License – You need to license the backup software on the entire footprint
So, on 1 PB of data, you are spending 4PB of storage on backup and DR, and 1PB of backup
license. Estimate the costs of these in your environment.
