db2 备份出现不解的错误

这是脚本：
/home/db2inst1/sqllib/db2profile
db2 backup db sias online to /home/db2inst1/db2backup include logs

[db2inst1@alan ~]$ ./db2backup.sh  
SQL2413N  Online backup is not allowed because the database is not recoverable
or a backup pending condition is in effect.



执行脚本出现这样的这样的错误提示，请各位高人指点迷津...收起
