When operating synchronously , provides for zero work loss through delayed commit on the principal database 同步操作時(shí),為了提供零工作丟失,將在主體數(shù)據(jù)庫上延遲提交。
If the tail - log backup succeeds , you can avoid any work loss by restoring the database up to the point of failure 如果尾日志備份成功,則可以通過將數(shù)據(jù)庫還原到故障點(diǎn)來避免任何工作丟失。
Before first database backup in this figure , the database is exposed to potential work loss from time t0 to time t1 在此圖中的第一個(gè)數(shù)據(jù)庫備份創(chuàng)建之前,數(shù)據(jù)庫存在潛在的工作丟失風(fēng)險(xiǎn)(從時(shí)間t0到時(shí)間t1 ) 。
A tail - log backup is taken after a failure in order to prevent work loss and can contain either pure log or bulk log data 在發(fā)生故障后提取尾日志備份,以防止工作丟失,該備份中可以包含純?nèi)罩緮?shù)據(jù)也可以包含批量日志數(shù)據(jù)。
Under the simple recovery model , after each backup , the database is exposed to potential work loss if a disaster were to occur 在實(shí)現(xiàn)備份與還原策略之前,應(yīng)當(dāng)估計(jì)完整數(shù)據(jù)庫備份將使用的磁盤空間。備份操作會(huì)將數(shù)據(jù)庫中的數(shù)據(jù)復(fù)制到備份文件。
These recovery models rely on backing up the transaction log to provide full recoverability and to prevent work loss in the broadest range of failure scenarios 這些恢復(fù)模式基于備份事務(wù)日志來提供完整的可恢復(fù)性及在最大范圍的故障情形內(nèi)防止丟失工作。
To help prevent work loss before an offline restore or after a failure , we recommend that you back up the tail of the log to capture any log records that are not yet backed up 如果要將數(shù)據(jù)庫還原到事務(wù)日志備份內(nèi)的某個(gè)時(shí)點(diǎn),則建議您保留丟失的日志備份之前的事務(wù)日志備份。
Sql server 2005 usually requires that you take a tail - log backup before you start to restore a database . the tail - log backup prevents work loss and keeps the log chain intact 除非restore語句包含with replace或with stopat子句,否則,還原數(shù)據(jù)庫而不先備份日志尾部將導(dǎo)致錯(cuò)誤。
We recommend taking frequent enough log backups to support your business requirements , specifically your tolerance for work loss such as might be caused by a damaged log drive 與數(shù)據(jù)庫備份相比,事務(wù)日志備份通常使用更少的資源。因此,相對(duì)于數(shù)據(jù)庫備份,您可以更頻繁地創(chuàng)建事務(wù)日志備份,從而降低丟失數(shù)據(jù)的風(fēng)險(xiǎn)。
