Access "Snapshot: Remote mirroring for data"
This article is part of the Vol. 3 No. 10 December 2004 issue of How does your storage salary stack up?
Do you mirror your data remotely? Do you mirror your data to remote locations? At what distance is data remotely replicated? What technique(s) do you use?

Over the next couple of years, more than 63% of respondents that don't already replicate remotely plan to start.
