Symptoms

AlwaysON 数据库的 Avamar SQL 备份完成，但出现异常。
完整备份后强制增量备份失败，并显示以下错误：“Error: A log gap was identified or a full backup was not found“

以下是日志中的片段： 
2017/11/09-18:48:57.86599 [avsql_assist]  ===> sqlconnect::~sqlconnect
2017/11/09-18:48:57.86599 [avsql_assist]  <=== sqlconnect::~sqlconnect
2017/11/09-18:48:57.86599 [avsql_assist]  <=== avsql_assist::snapup_check_timestamps
2017-11-09 13:48:57 avsql Error <15762>: Skipping incremental backup after full for <AlwaysON_DB_Name> database. Error: A log gap was identified or a full backup was not found.

为数据集中的备份选择了辅助副本。
未进行第三方或本机备份。

Cause

SQL Server 中的日志序列号 （LSN） 编号与备份元数据不匹配。
在主副本上执行完整 + 增量备份时会导致此问题。
 

Resolution

要解决此问题，请将 Avamar Server 升级到以下 Avamar 软件版本：
  • 19.4.100-124 或更高版本
