Cost of Storage – Elements 5 & 6 that make up TCSO
by David Merrill on Sep 29, 2006
#5 Backup Window Time / Cost- Backup window time has a cost. This is often related to the recovery time objective or RTO. Stopping applications to back them up, impacts business operations. Slowing down networks, hosts and the storage infrastructure during intense backup times is an impact, and can be quantified in dollars (opportunity loss or opportunity costs). Many IT shops are looking to disk-based backup, snapcopy and VTL to reduce the backup window time and cost.
#6 Recovery time/cost from a catastrophic event – If/when catastrophic outages hit, IT and business will suffer outage time Engineering rapid recovery services can reduce application and business downtime. For catastrophic events, business and IT resumption should have defined value to the enterprise. Being able to recover faster, can reduce risks and loss from an outage. Again, these are business risk costs and opportunity costs that are defined with a faster recovery. Solutions to enable catastrophic fast recovery include remote site mirroring, synchronous replication etc.
