Your question is a very good one. Many of the respected storage solution
providers now have a "spinning disk" alternative (or add-on or integration)
for backup and disaster recovery plans. Which you use (or both) just depend
on your specific backup and disaster recovery needs. Due to the lowering
costs of spinning disk solutions, and the speed of restoring data, they are
becoming more popular. You will probably get a lot of "advice" here. But you
have to make the decision yourself based on your own needs. Here are some
things to think about (not an all inclusive list).
- How important is my data?
- What is the cost in money, time or reputation of my data is lost?
- How extensive is the effort to recreate my data, if lost?
- Can my data be recreated if lost?
- What is the cost of the protective measures? (i.e. disks, time, tape, etc)
- Does cost of protection exceed cost of recreation?
- If lost, how fast will I need data restored? (takes longer from tape)
- Do I need incremental backups or are snapshots good enough?
- Do I need the capability to "roll-back" transactions to specific
dates/times?
There are more....
Your decision.
