- 关闭所有到数据库的连接，将数据库置为“静默”状态：
db2 connect to sample user dbeinst1 using dbeinst1
db2 quiesce database immediate force connections
db2 connect reset
- 创建备份目录并给权限
mkdir /home/dbeinst1/db2backup
chmod 775 /home/dbeinst1/db2backup
- 开始备份
db2 backup database sample to "/home/dbeinst1/db2backup"
- 备份后的数据文件为
/home/dbeinst1/db2backup/SAMPLE.0.dbeinst1.DBPART000.20180522165141.001
- 解除数据库的“静默”状态
db2 connect to sample user dbeinst1 using dbeinst1
db2 unquiesce database
db2 connect reset
- 相同库名恢复：
db2 restore database sample from "/home/dbeinst1/db2backup"
- 不同库名恢复：
db2 restore database sample from "/home/dbeinst1/db2backup" into sampl1
