您要查找的是不是：
- Tail log backups capture the tail of the log even if the database is offline, damaged, or missing data files. 尾日志備份可捕獲日志尾部,即使數據庫離線(xiàn)、損壞或缺少數據文件。
- If the tail of the log is damaged, changes since the most recent log backup must be redone. 如果日志尾部損壞,則必須重做自最新日志備份之后所做的更改。
- In this case, you do not have to have a log backup. 在這種情況下,不必準備日志備份。
- The time and date of the last log backup operation. 上一次日志備份操作的時(shí)間和日期。
- If the tail of the log cannot be backed up, you can restore the database only to the time of the most recent regular log backup. 如果日志尾部無(wú)法備份,則可以將數據庫僅還原到進(jìn)行最近常規日志備份的時(shí)間點(diǎn)。
- This parameter identifies a transaction mark in the log backup. 此參數在日志備份中標識一個(gè)事務(wù)標記。
- The database must be recovered to the end of a transaction log backup. 必須將數據庫恢復到事務(wù)日志備份的結尾。
- We recommend starting then because the first log backup can take a long time. 之所以建議在此時(shí)開(kāi)始備份,是因為第一個(gè)日志備份會(huì )花費較長(cháng)的時(shí)間。
- This can slow down database startup and also log backup and restore operations. 這會(huì )降低數據庫啟動(dòng)以及日志備份和還原操作的速度。
- Apply the transaction log backup that was created at 5:10 A.M. On Wednesday. 應用星期三凌晨5:10創(chuàng )建的事務(wù)日志備份。
- Some time after the Log_2 log backup, data loss occurs in the database. 在Log_2日志備份后的某個(gè)時(shí)間,數據庫出現數據丟失。
- A bulk log backup includes log and data pages changed by bulk operations. 批量日志備份包括由批量操作更改的日志和數據頁(yè)。
- Restoring a log backup rolls forward all pages in the roll forward set. 還原日志備份將對前滾集中的所有頁(yè)進(jìn)行前滾。
- This can make the log backups very large. 這會(huì )使日志備份非常大。
- When you use back up the tail of the log on a damaged database, some of the metadata ordinarily captured in log backups might be unavailable. 對受損數據庫備份日志尾部時(shí),日志備份中正常捕獲的部分元數據可能不可用。
- A tail-log backup is a log backup taken right before restoring a database, typically after a failure on the database. 尾日志備份指在還原數據庫之前(通常在數據庫出現故障之后)執行的日志備份。
- Before you can create the first log backup, you must create a full backup, such as a database backup. 在創(chuàng )建第一個(gè)日志備份之前,您必須先創(chuàng )建一個(gè)完整備份(如數據庫備份)。
- The Database Engine might prevent you from reusing a name until you take a log backup. 數據庫引擎可能會(huì )在進(jìn)行日志備份之前阻止您重新使用名稱(chēng)。
- For each extent updated by a bulk-logged operation since the last log backup, the bit is set to 1 in the bitmap. 對于自上次日志備份后由大容量日志操作所更新的每個(gè)區,在位圖中將每個(gè)位都設置為1。
- However, first, at least one log backup must be taken on the principal database. 但是,首先在主體數據庫中必須至少執行一個(gè)日志備份。
