Host Based Data Replication

• Advantages
• Software-Based (Cheap)
• Quick to Implement
• No SAN required
• Flexible, able to add new features as new
  software versions come out
• More flexible

• Disadvantages
• May require several products
• VM Only or Product Specific
• Doesnt always support differential copy
• YAV (yet another vendor)

VMWare Array Based Data Replication

WAN or Dark Fiber

Array Based Data Replication

• Advantages
• SAN and recovery all-in-one
• Block-Level, both physical and virtual data can
  be replicated with same process
• Integration with many backup products like
  Netbackup

• Disadvantages
• Can be spendy
• May or may not quiesce data
• Lock-In
• Vendor features vary wildly
• Requires SAN experience
• Replication is often not compressed (high
  bandwidth requirements)

VMWare Site Recovery Manager

• Newly Announced at VMWorld 2007
• Integration with Array (and maybe host?)
  replication SAN vendors to automate recovery
  processes and make recovery process easy(ier)
• Not much info available now, ask again later!
