That is, you can restore a backup image from a lower DB2 version into a higher version, but not the opposite.
可以将来自较低版本的DB2的备份镜像恢复到较高版本的DB2，但是反之则不行。
Therefore, the restore will be according to the backup timestamp to ensure the latest backup image is restored in order to minimize the loss of data.

The database backup image contains the DB2 agent module and information required for decrypting it.
数据库备份映像包含用于解密的DB2代理模块和信息。
Instead, the changes between each backup image are captured in the DB2 logs.
相反，每个备份映像之间的更改被DB 2日志捕获。
If a delta is preceded by an incremental backup image, you need the delta, the incremental backup, and the full backup image on which the incremental is based.
如果在增量备份之前执行了增量备份，则需要增量备份、增量备份以及增量备份所依赖的完整备份映像。
By default, the transaction log will be copied back to the same location that it was in, when the backup image was taken.
默认情况下，事务日志将被复制回当初备份时所在位置。
Restore log file option restores the log files saved in the backup image (more applicable for online backup and restore).
