两者都能执行完全系统备份。
这是完全系统备份，您要定期执行以保存整个系统。
This is the full system backup that you would do periodically to capture the entire system.
全系统备份是某一指定时间点(即归档检查点)上整个系统的快照。
A whole-system backup is a snapshot of the entire system at a single point in time (known as the archive checkpoint).
全系统备份本身就是很好的主意，我希望您不定期地对系统进行备份。
Full system backups are good things in their own right, and I hope you back up your system on at least a semi-regular basis.
如果您正在计划对您的Linux系统进行重大升级，则现在可能是执行全系统备份的好时机。
If you're planning on making major upgrades to your Linux system, this may be a good time to perform a full system backup.
我们相信，Google能够创建一项功能来进行全系统备份而无需让用户能够读取整个ROM空间，如果那是他们想要的话。

如果您想恢复一个Whole-System-Backup（完全系统备份），那么并不需要指定'-w'标志。

对于这两种类型的备份(全系统备份和并行备份)，都可以指定备份级别，例如，如果此备份应该是一个完全备份或增量备份。
For both types of backups (whole system and parallel) you will be able to specify the backup level, for instance, if this should be a full or an incremental backup.
全系统备份是连续执行的(一个dbspace备份完成后接着另一个dbspace备份)，并且可以不使用任何逻辑日志来还原它们。
Whole-system backups are performed sequentially (dbspace after dbspace) and they can be restored without applying any logical logs.
在并行备份期间，不管是标准备份(onbar -b)还是全系统备份(onbar - b - w)，都是多个进程同时运行，并将数据备份到不同的dbspace中。
During a parallel backup, whether it is a standard backup (onbar -b) or whole-system backup (onbar -b -w), multiple processes run simultaneously and back up data to separate dbspaces.
在不远的将来，很多组织会将其基础设施如邮件，备份和安全系统迁移至SaaS应用，以租赁方式来节省开销。
In the near future, many organizations will, for example, dispense with their own infrastructures for E-mail, backup, and security - and save costs by renting instead.
