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:
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
