双语例句
- Dealing with huge databases such as those in data warehouse environment, both Oracle and DB2 provide incremental and differential backup to avoid copying unchanged data pages.
在处理像数据仓库环境中数据库那样的巨型数据库方面，Oracle和DB2都提供了增量和差异备份，避免复制未更改的数据页。 - The diagram below illustrates the concept of differential incremental backup.
下图阐述了差异增量备份的概念。 - Differential incremental backup backs up all blocks changed after the most recent backup at level n or lower.

部分差异备份，基于部分备份。 - After a full file restore, a differential file backup can be restored.
完整文件还原之后，便可还原差异文件备份。 - If you must recover a store, you must recover the store itself from the last normal backup, and then you can recover log files from an incremental or differential backup.
如果必须恢复存储，必须先从上一次普通备份恢复存储本身，然后才能从增量备份或差异备份恢复日志文件。 - Immediately after you complete the switch to the full recovery model or bulk-logged recovery model, take a full or differential database backup to start the log chain.
从简单恢复模式切换到完整模式之后，建议您：立即执行完整数据库备份或差异数据库备份。 - To make differential backup, restore, and recovery of full-text catalogs possible, the full-text catalog must be stored in a directory that is part of an NTFS file system.
若要使全文目录能够进行差异备份、还原和恢复，必须将全文目录存储在属于ntfs文件系统的目录中。 - The differential bitmap was invalidated for database%. ls. A full database backup is required before a differential backup can be performed.
数据库%1！在差异备份位图已作废。需要执行完整备份后，才能执行差异备份。 - A differential backup contains just enough log to allow recovery.
