【IT168 服务器学院】关于分区数据库的备份和恢复：
　　备份：
　　db2_all ''<<+0<db2 backup db sample online to /home/db2inst1/db2backup/online''
　　db2_all ''<<-0<db2 backup db sample online to /home/db2inst1/db2backup/online''

　　恢复：
　　db2_all ''<<+0<db2 restore db sample from /home/db2inst1/db2backup/online''
　　db2_all ''<<-0<db2 restore db sample from /home/db2inst1/db2backup/online''
　　>>也可以并行
　　  备份
　　  db2_all "<<+0< db2 backup db sample online to /home/db2inst1/db2backup/online"
　　  db2_all "||<<-0< db2 backup db sample online to /home/db2inst1/db2backup/online"
　　  恢复:
　　  db2_all "<<+0< db2 restore db sample from /home/db2inst1/db2backup/online"
　　  db2_all "||<<-0< db2 restore db sample from /home/db2inst1/db2backup/online"

　　前滚：
　　db2_all ''<<+0<db2 rollforward db sample to end of logs on all partitionnums and stop''
　　执行此命令之前，要把所需要的日志放置到指定目录上，具体可参考单节点数据库的备份、恢复与前滚
