The  Best  HA/DR  Solu%on  for  Today’s  Enterprise  

Double-­‐Take  DR  –  What  is  it?  •  Double-­‐Take  DR  is  for  the  protec%on  of  en%re  servers  (Windows  

only)  or  data  that  can  afford  a  longer  RTO  at  a  frac%on  of  the  cost  of  Double-­‐Take  Availability  

•  Can  be  used  for  DR  of  Tier  2  and  Tier  3  servers  that  do  not  require  the  low  RTO  of  Availability  

•  Can  be  used  to  supplement  exis%ng  local  HA/DR  strategies  

•  S%ll  offers  sub-­‐second  RPO  to  minimize  data  loss  

•  Can  be  used  for  centralized  backup  scenarios  

Double-­‐Take  DR  for  Windows  –  High  Level  View  

1.  Source machine can be 2003, 2008, or 2012 on any platform either locally or remote

2.  Target machine is 2008 R2 or later and .VHD files are used for each volume protected

3.  Recovery machine can be any platform or even the source but must match source OS and

architecture if recovering the entire server as data only can be recovered to any machine

anywhere

The Double-Take driver sees bytes of I/O en route to

the file system and copies them

into memory

As confirmation of the write travels

back to the application, Double-

Take then sends the bytes to the

target
