I backed up a database:
(我备份了一个数据库:)
BACKUP DATABASE MyDatabase
TO DISK = 'MyDatabase.bak'
WITH INIT --overwrite existing
And then tried to restore it:
(然后尝试恢复它:)
RESTORE DATABASE MyDatabase
FROM DISK = 'MyDatabase.bak'
WITH REPLACE --force restore over specified database
And now the database is stuck in the restoring state.
(现在数据库仍处于恢复状态。)
Some people have theorized that it's because there was no log file in the backup, and it needed to be rolled forward using:
(有些人认为这是因为备份中没有日志文件,需要使用以下方式前滚:)
RESTORE DATABASE MyDatabase
WITH RECOVERY
Except that, of course, fails:
(当然,除此之外,失败:)
Msg 4333, Level 16, State 1, Line 1
The database cannot be recovered because the log was not restored.
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.
And exactly what you want in a catastrophic situation is a restore that won't work.
(确切地说,在灾难性的情况下你想要的是一种无法恢复的恢复。)
The backup contains both a data and log file:
(备份包含数据和日志文件:)
RESTORE FILELISTONLY
FROM DISK = 'MyDatabase.bak'
