RAID != backup

(for my fortran bretheren, != -> .ne. )

On /. is an object lesson in what not to do for valuable data.

Backups are important. This cannot be stressed enough.

More to the point, there are many things that are not backups.

Snapshots come to mind. Yet we see people use them in this manner.

In this day and age with “dedup” the fad d’jour (all it does is make each block that much more valuable, and important not to have go away …) backup is ever more important.

We have customers using JackRabbit and now ΔV as backup targets, from JackRabbit and other storage systems.

Important data needs backup/replication to other unconnected systems, to make restoration possible.
