任何在随后时间里被修改过的文件又会在归档位中记录下来。 差量备份(differential backups)不会在备份完成后清除归档块,而增量备份会在完成后清除归档块,这样就能避免有些文件不必要地再次被备份。使用归档块还能使用户真实地查看到那些文件需要备份。 速度更快的备份也需要付出有些代价——在这个情况下, 就是恢复...
To learn what incremental and differential backups are, first of all, you need to know what a full backup is. A full backup is to back up all the targets you selected as the backup source. For example, if you choose all the photos in the Pictures folder on your PC, a full backup ...

① Differential Incremental Backup (for level 1 parents only) 当使用 Differential backups、RMAN 寻找最近一次 level 1 之后有变化的块、如果找不到 level 1、则会捕获从最近一次 level 0 之后所有变化的块 ② Cumulative Incremental Backup (for level 0 or level 1 parent backups) 对于Cumulative backups...
Differential backup vs. incremental backup: what’s the difference? A full backup, as the name suggests, creates a complete copy of all selected files and data. It serves as a baseline backup, capturing every bit of information at a specific point in time. On the other hand, differential ...
答案:Differential 和 cumulative 是 RMAN incremental backups 的两种类型。有时候、RMAN differential backups 被叫做 RMAN cumulative Backups 然而、RMAN incremental backups 、有时、也会被叫做 RMAN differential Backups。以上这些情况、很容易让人迷惑不解 ...

Well, that’s literally what “backup” means. However, there are different types of backups, mainly “Differential Backup” and “Incremental Backup.” These types of backups come in handy when you deal with big data; thus, you need to know more about them. ...
