SQL Server的近連續數據保護(CDP)

With version 4.5, ZCB now supports incremental (log-based) backups of SQL Server. This helps a great deal since log backups contain a list of all the individual changes to the database, and hence, provide an ability to restore the database to 任何 歷史時間戳記,與實際備份時間無關。

我們為什麼稱這個 -CDP而不是CDP?請注意,日誌備份不會在每次更改事件時自動觸發,並且仍然是“基於計劃的”。雖然這可以最大程度地減少CPU /內存/帶寬資源上的備份開銷,但這也意味著您只能還原到時間戳記 之前 日誌備份已成功進行。也就是說,請注意,您始終可以選擇更高的日誌備份頻率(例如,“每15分鐘”),以使其盡可能接近真正的CDP系統。

這是可以指定的方式 任何 還原時間點:

While we’re discussing SQL Server backups, there is some more good news:  ZCB now performs Virtual Device Interface (VDI) based differential backups that can be 顯著地 more compact and efficient than our earlier VSS based differential backups!
