1: 假如你有一个全备，然后你在它之后做了一些日志备份，然后又做了一个差异备份，然后又做了一些日志备份，接下又做了一个差异备份，然后又做了一些日志备份，此时Sql server 崩溃，并且发现差异备份文件损坏，但全备和日志备份文件正常，这种情况下能否将数据库还原到当前时间点而不用差异备份？
2: 假设同样是问题一的情况，但把差异备份换成是全备，即顺序为全备、日志备、全备、日志备、全备、日志备，现在第二、三个全备都损坏，当Sql server 崩溃时，能否将数据库还原到当前时间点而不用差异备份？

Question 1: Consider a scenario where you issue a full backup. Then issue some transaction log backups, next a differential backup, followed by more transaction log backups, then another differential and finally some transaction log backups. If the SQL Server crashes and if all the differential backups are bad, when is the latest point in time you can successfully restore the database? Can you recover the database to the current point in time without using any of the differential backups?
假如你有一个全备，然后你在它之后做了一些日志备份，然后又做了一个差异备份，然后又做了一些日志备份，接下又做了一个差异备份，然后又做了一些日志备份，此时Sql server 崩溃，并且发现差异备份文件损坏，但全备和日志备份文件正常，这种情况下能否将数据库还原到当前时间点而不用差异备份？
Question 2: Assume the same scenario, however instead of issuing differential backups, all three of the differential backups were full backups. Assume all the full backups are corrupt with the exception of the first full backup. Can you recover the database to the current point in time in this scenario?
