sql - 使用文件组的目的

Question

我不明白在 SQL Server 中使用 Filegroup 的目的？它可以提供什么好处？

Answer 1

If you're using Enterprise Edition, you can do a piecemeal restore. That is, you can place critical and not-so-critical tables on different filegroups and, in the case of disaster, recover them at different times. This requires a lot of forethought, but is handy.
