本文讨论对数据仓库的最大备份改进之一——增量备份。
This article discusses one of the most powerful backup improvements for data warehouses - incremental backup.
要指定是否对数据库启用增量备份,需要使用TRACKMOD配置参数。
To specify whether incremental backup is enabled for a database, you use the TRACKMOD configuration parameter.
换句话说,您必须对数据库进行完整的备份,从而为执行增量备份提供一个基准点。
In other words, you must take a full database backup so that you have a baseline against which incremental backups can be taken.
本文对数据成时间序列的动态决策表,用增量式算法提取决策表的规则模型。
In this paper, we extract rules of the decision table by an incremental algorithm for the dynamic decision table of the time series data.
为使通过QC树对数据仓库进行常规的增删改操作和查询操作变得更加方便和高效,提出了QC树增量维护和有效查询的详细实现算法。
In order to make it more convenient and more effective to add, delete, update and query a data warehouse through QC-tree, this paper suggested how to incrementally maintain and query QC-tree.
但现在由于我在永久进行增量块级备份,就能开始极其频繁地对数据拍取快照。
But now because I'm doing incremental block level forever, I can start taking snapshots of my data much more frequently.
