儲存在 Data Domain 上的用戶端備份後端容量報告是 Avamar 7.3 版推出的新功能。
 

注意：Data Domain 5.7.0.0-496793 或更新版本為必填。

後端容量報告適用於 GSAN自 Avamar 版本 5.x 起提供，使用複寫技術來計算重複資料刪除後的備份大小。

若要報告儲存在 Data Domain 上的用戶端備份，DDOS 會使用實體容量測量 （PCM） 或實體容量報告 （PCR） 功能。這可讓您透過目錄樹狀結構、目錄樹狀集合、MTree 或 MTree 集合來計算準確的磁碟用量。下列文章提供了詳細說明：Data Domain：實體容量測量或實體容量報告常見問題

下列步驟使用管理主控台伺服器 （MCS） 記錄，概述 Avamar 如何使用 PCM 功能取得儲存在 Data Domain 上的備份的後端容量報告資訊：
  1. 當後端容量報告啟動時，MCS 服務會產生執行緒來執行報告：
03/31-13:17:01.00044 com.avamar.mc.rpt.job.ReportManager$1.run 
INFO: Started: com.avamar.mc.rpt.job.BackendCapacityDDReportJob@a471a6aa (1 running, 0 waiting) 

03/31-13:17:01.00045 com.avamar.mc.rpt.job.BackendCapacityDDReportJob.run 
FINE: Running report <REPORT_NAME>
  1. MCS 會擷取報告中所選之用戶端或網域的備份：
03/31-13:17:01.00045 com.avamar.mc.rpt.job.BackendCapacityDDReportJob.publishStatus 
FINE: Fetching backups 

03/31-13:17:01.00119 com.avamar.mc.rpt.job.BackendCapacityDDReportJob.fetchBackups 
FINE: Including domain: /clients/ 

03/31-13:17:01.00203 com.avamar.mc.rpt.job.BackendCapacityDDReportJob.getClientBackups 
FINE: Including client: /clients/test.local.domain (23 backups)(test.local.domain)
  1. 收集所有備份後，MC 會呼叫 Data Domain 的 REST API，以建立壓縮測量：
03/31-13:17:13.00602 com.avamar.mc.rpt.bcrdd.CompressionMeasurement.<init> 
FINE: Creating URI: https://dd.local.domain:3009/rest/v1.0/dd-systems/d57a21caedf6d961%3Ac514d833dda5914e/stats/compression/measurements 
03/31-13:17:13.00602 com.avamar.mc.rpt.job.BackendCapacityDDReportJob.publishStatus 
FINE: Created measurement for: dd.local.domain

測量包括所有用戶端的備份：

03/31-13:17:13.00605 com.avamar.mc.rpt.job.BackendCapacityDDReportJob.publishStatus 
FINE: Submitting measurement 1 of 1

  1. 報告可能需要幾分鐘才能完成，在此期間，MCS 會繼續監控 Data Domain 的測量結果：
03/31-13:21:12.00658 sun.net.www.protocol.http.HttpURLConnection.getInputStream0 
FINE: sun.net.www.MessageHeader@1017660a7 pairs: {null: HTTP/1.1 200 OK}{Content-Type: application/json}{Content-Length: 553}{X-DD-AUTH-TOKEN: c6cd873bdaf7c3861d60ba35e10eab189}{X-DD-UUID: d57a21caedf6d961:c514d833dda5914e}{Cache-Control: no-cache}{Server: Data Domain OS 5.7.2.10-541351} 
03/31-13:21:12.00658 com.avamar.mc.rpt.job.BackendCapacityDDReportJob.publishStatus FINE: Monitoring 1 measurements
  1. 在 Data Domain 上完成測量後，MC 會收到以下資料：
03/31-13:22:18.00806 sun.net.www.protocol.http.HttpURLConnection.getInputStream0 
FINE: sun.net.www.MessageHeader@6e4fa4fb7 pairs: {null: HTTP/1.1 200 OK}{Content-Type: application/json}{Content-Length: 984}{X-DD-AUTH-TOKEN: c6cd873bdaf7c3861d60ba35e10eab189}{X-DD-UUID: d57a21caedf6d961:c514d833dda5914e}{Cache-Control: no-cache}{Server: Data Domain OS 5.7.2.10-541351}

  1. MCS 會完成工作，並將報告資料插入 report_history MCS 資料庫 （MCDB） 的表。這可讓您從 Avamar UI 檢視報告：
03/31-13:22:18.00814 com.avamar.mc.rpt.job.BackendCapacityDDReportJob.run FINE: Finished (317769 ms)

注意：Data Domain 的後端容量報告不包括儲存至 Avamar 的備份 GSAN 倉庫。同樣地，「後端容量」報告 GSAN 不包括 Data Domain 上的備份。
