在下面的例子中，我将演示如何使用JFS2快照来在升级过程中备份和恢复文件系统。
In the following examples, I demonstrate how I used JFS2 snapshots to backup and recover a file system during an upgrade activity.
例如，使用快照，在需要修改多个配置文件或对应用程序执行升级时，我可以加快备份和恢复速度(如果需要)。
For example, using snapshots, I can speed up the backup and (if necessary) the recovery times when I need to modify a number of configuration files or perform an upgrade of an application.
虽然由于备份集不可用而导致队列管理器恢复失败的情况不常发生，但是我还是看到过几次这样的情况。

假如备份了我的应用程序，而不仅是我的私人数据文件，那么可能已经恢复了数据。
Had I backed up my applications, not just my personal data files, I could have recovered the data.
当我这次恢复这个数据库时，在备份起头之前再也不需要等待5分50秒，我只等待了2秒。
When I restored the database this time around, instead of having to wait 5 minutes and 50 seconds before the backup began to restore, I only had to wait just under 2 seconds.
现在还有一个很细节的地方没有做修复，就是INT类型的数据，备份的恢复问题！这个不太好做，大家容我点时间！
Now there is a very details of the place does not do repair is INT type of data backup recovery issues!
