討論了用于創(chuàng)建日志鏈的最重要的日志序列號(hào)。 - If you switch from the full or bulk - logged recovery model to the simple recovery model , you break the backup log chain
如果從完整恢復(fù)模式或大容量日志恢復(fù)模式切換到簡(jiǎn)單恢復(fù)模式，則需要中斷備份日志鏈。 - It's difficult to find log chain in a sentence. 用log chain造句挺難的
- We recommend that you never use no log or truncate only to manually truncate the transaction log , because this breaks the log chain
盡管可用此選項(xiàng)手動(dòng)截?cái)嗍聞?wù)日志，但是極力建議您不要這樣做，因?yàn)檫@會(huì)將日志鏈斷開(kāi)。 - If a transaction log backup in this log chain is lost or damaged , you can restore only transaction logs before the missing transaction log
如果此事務(wù)日志鏈中的事務(wù)日志備份丟失或損壞，則您只能還原丟失的事務(wù)日志之前的事務(wù)日志。 - The database mirroring synchronous mode guarantees that the log chain is unaffected by a mirroring failover and that only valid log is restored
數(shù)據(jù)庫(kù)鏡像同步模式可以保證日志鏈不受鏡像故障轉(zhuǎn)移的影響，也可以保證只還原有效的日志。 - Immediately after you complete the switch to the full recovery model or bulk - logged recovery model , take a full or differential database backup to start the log chain
從簡(jiǎn)單恢復(fù)模式切換到完整模式之后，建議您：立即執(zhí)行完整數(shù)據(jù)庫(kù)備份或差異數(shù)據(jù)庫(kù)備份。 - The copy - only log backup has no effect on the log chain , and other log backups behave as if the copy - only backup does not exist . for more information , see
在進(jìn)行完整數(shù)據(jù)庫(kù)備份或差異備份時(shí)， sql server會(huì)備份足夠的事務(wù)日志，確保還原數(shù)據(jù)庫(kù)時(shí)生成一個(gè)一致的數(shù)據(jù)庫(kù)。 - 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

這些選項(xiàng)通過(guò)放棄活動(dòng)日志以外的所有日志，無(wú)需制作日志的備份副本即可刪除不活動(dòng)的日志部分，并中斷日志鏈。 - These options break the log chain , because they remove the inactive part of the log without making a backup copy of it and truncate the log by discarding all but the active log
例外情況是如果檢查點(diǎn)發(fā)生在backup語(yǔ)句仍活動(dòng)時(shí)，則不截?cái)嗳罩?。有關(guān)自動(dòng)檢查點(diǎn)間隔的詳細(xì)信息，請(qǐng)參閱 - However , if the old log file is not found and if the database was shut down cleanly and has no active log chain , the attach operation attempts to build a new log file for the database
但是，如果未找到舊文件日志，數(shù)據(jù)庫(kù)上次是完全關(guān)閉且現(xiàn)在沒(méi)有活動(dòng)日志鏈，則附加操作將嘗試為數(shù)據(jù)庫(kù)創(chuàng)建新的日志文件。 - If a log backup becomes missing or damaged , start a new log chain by creating a full or differential database backup and then backing up the transaction log to start a new log chain
完整的日志鏈要求事務(wù)日志備份序列不能中斷，它從完整備份或部分備份（或者部分完整備份或部分差異備份）結(jié)尾一直擴(kuò)展到恢復(fù)點(diǎn)。
