Why the Cloud?
"Each Microsoft product group is moving to the cloud as a fundamental business platform.”
-Microsoft Build, 2011
“This is the bet for the company. For the cloud, we’re all in”
-University of Washington, 2010
MSIT should have the goal of "making the cloud the center of our IT development and planning process."
-Memo 2011

Database Backup & Restore
• Two concepts
• Fly all databases to SPO datacenter and restore
• Longer read only window, done in one fell swoop
• Break into batches
• Sites stay in Read/Write while db’s flown over
• Sites locked when incremental updates flown over following weekend
• Limits Read Only window to 72 hours; weekend maintenance windows

Site Collection Backup/Restore :
• Granularity to keep the read/only window ~ 24 hours, enabled weekday execution
• Site Restore triggers the link fix-up we need to move the host name
• ~ 200 GB or ~1000 sites per day (whichever comes first)
• Requires two staging environments, very manual
