If a mirror has already been completed, another full mirror will overwrite the data on the target. Difference Mirror Compares all files in the replication set on the source and their current state on the target machine. The comparison is based on the date, time, and size of the file (DTS-Check). Changes can be transmitted on file or block level. NEW: Use of the NTFS Change Journal The difference mirror after a reboot of the source server only checks the changed files since Double-Take services stoped. This dramatically shortens the mirror times after a (planned) reboot!
