Backup exec 備份MS SQL時 只能完整備份

 環境:

Backup exec 

Commvault

MS SQL

異常狀況:

Backup exec 備份MS SQL時，，設定差異備份，還是只會執行完整備份

解決過程:

Commvault 虛擬機備份設定中，如果選擇了File System and Application Consistent，就會把之前Backup exec 對MS SQL備份的備份鏈資訊重置，造成Backup exec之後備份必須做完整備份。

所以要把Commvault 虛擬機備份設定改成下面的Crash Consisten。

Environment:

Backup Exec

Commvault

Microsoft SQL Server

Issue:

When using Backup Exec to back up MS SQL Server, the job is configured for Differential Backup, but it always performs a Full Backup instead.

Resolution:

In the Commvault virtual machine backup settings, if “File System and Application Consistent” is enabled, it resets the SQL backup chain information previously created by Backup Exec.

As a result, Backup Exec is forced to perform a new Full Backup before Differential Backups can continue.

To avoid this issue, change the Commvault VM backup setting from:

• File System and Application Consistent

to:

• Crash Consistent
