Which way should we choose to shorten backup time?

A company performs a full backup for its data in a daily basis for disaster recovery purposes. However, their backup process cannot be completed within the assigned backup time window.
What would you recommend to this company about how to restructure its backup environment in order to minimize the backup time? We got 4 candidates,
1. Perform LAN based backup
2. Weekly full backup and daily incremental
3. Weekly full backup and daily cumulative
4. Add more ISL to increase bandwidth
when comparing incremental backup with cumulative backup ,incremental backup time is surely shorter than cumulative backup time .But I don's know adding more ISL is allowed in an existing storage system,or can this operation really shorten backup time ?
