When the secondary site conducts remote business recovery, the backup data chain of secondary
site will be inconsistent with that of primary site; in other words, when the data center of primary
site breaks down, the backup files will be lost at the primary site and then the full image files and
incremental backup files synchronized from the primary site will exist at the secondary site. Then
full migration is conducted.
There are four specific scenarios as follows:
1) The primary site loses all the backup files (including the full image files and incremental
backup files.
2) The primary site loses the full image files and part of incremental backup files.
3) The primary site loses part of incremental backup files before the secondary site is recovered.
4) The primary site loses all the incremental backup files.
