I've been reading about database mirroring on SQL Server 2008 R2 / 2012 and I have a question: does it matter if the database being mirrored is live? Do I have to do anything special or different if my database is live?
- I have a (one) database on premises that's our production database. A few hundreds transactions happens per second, and 99.999% are read operations. Our plan is to mirror this database (single database) to SQL Azure (IaaS) as a "backup" structure, if the on premises environment crash for any reason, we just point to the cloud.
- I would like a zero loss, but I settle for a 5 seconds loss
- Latency wont be a problem... slow running is better than no running...
- I have just one node and one database
