The common practice is to start a partial restore sequence by restoring a partial backup 但是，在恢复点处，未还原的文件组将失效。
2.
Each filegroup - restore sequence restores and recovers one or more offline filegroups to a point consistent with the database 未还原的文件组被标记为离线，不能对其进行访问。
3.
Piecemeal restore is available for a read - only secondary filegroup only if the following are true : was read - only when backed up 而在sql server 2000中，部分还原后，未还原的文件组将失效。
