4. connect to pb_db --- connection;

5. create bufferpool testpool size 2000 pagesize 32 k -- temporary tablespace buffer pool;

6. create temporary tablespace temp pagesize 32 k managed by database using (file '\ home \ db2inst1 \ rdl \ data' 5000) extentsize 80 bufferpool testpool -- temporary tablespace;

7. create bufferpool pbloop immediate size 1000 pagesize 32 k -- User tablespace buffer pool;

8. create regular tablespace pbxt pagesize 32 k managed by database using (file '\ home \ db2inst1 \ rdl \ data \ user' 1024 M) autoresize no extentsize 32 overhead 10.5 prefetchsize 32 transferrate 0.14 bufferpool pbloop -- User tablespace

Db2 backup db pb_db to/home/db2inst1/rdl/data back up the database in the data folder to generate a 001 File

The steps for restoring a Db2 database are as follows:

1. view the memo history:

Db2 list history backup all for pb_db;

2. Restore data at a certain time point:

Db2 restore database pb_db from/home/db2inst1/rdl/data taken at 20140625141510

In this case, a warning is displayed, and entering y will be restored.
