db2 connect to  odsdb user reportdb  using reportdb
db2 backup database odsdb  user reportdb  using reportdb    to e:\db2\backup 

db2 connect to  wasdb user db2admin  using db2admin
db2 backup database wasdb   user db2admin  using db2admin   to e:\db2\backup 


直接使用db2 backup db的命令，就可以完成你的需求，
如果系统出现问题，需要创建INSTANCE用户，再创建INSTANCE，再恢复DB
整个库的信息就全部恢复回来了。
