h1. Database Mirroring on remote site
h2. Introduction
To mirror production database(s) to remote site, there are a number of approaches:
# Use <code>(full)</code> database backup
# Use <code>(full + incremental)</code> database backup
# Use <code>(full + delta)</code> database backup
# Use <code>(full + incremental + delta)</code> database backup - _not recommended because it is too complex_
# Use <code>(full database backup + transaction logs)</code>
> the approach 1-4 are described in "Using DB2 incremental backup":http://www.ibm.com/developerworks/data/library/techarticle/dm-0910db2incrementalbackup/
The following sections will describe how the last approach actually works. Before that, let's do a compare:
