To ensure that in the event of a disaster data can be restored with the minimum
recovery point possible, the backup is split into equal sections and is run in the
space of a month.
This process requires that the maximum backup size is restricted to 15 TB for
any full backup. Each LUN then takes incremental updates for the rest of the
backup cycle until a full backup is due again.

Off-host vs. Network
Due to the size of data that needs to be moved onto tape for disaster recovery
purposes in most forensics labs, the LUNs storage is divided into 15 TB LUNs.
This requirement allows for easier management and backup, and it also reduces
file system cluster failure over time in the event of a failure.
