DR replica for a MS SQL 2005
Posted on 2010-09-14
We have a production SQL database and considering a DR instance for it. after a lot of research
I selected log shipping to keep secondary instance Suncronized with Primary one.
Today , this scenario crossed my mind ;
- let's say log shipping happens every 30 min. if something happens and we failover to DR instance; then we lose some changes that happened
during this period (0 to 30 min) , in addition ; users will make change to DR instance during the fail-over ; how all these changes will get merged
after Primary is backup ?
- Is there any utility or software to monitor this situation ? any suggestions ?
