Avamar: Sådan genereres en backend-kapacitetsrapport for sikkerhedskopier, der er gemt på et Data Domain

Backend-kapacitetsrapportering for klientsikkerhedskopier, der er gemt på Data Domain, er en ny funktion, der blev introduceret med Avamar version 7.3.
 

Backend-kapacitetsrapporten for GSAN, der har været tilgængelig siden Avamar version 5.x, anvender replikeringsteknologi til at beregne størrelsen af sikkerhedskopier efter deduplikering.

Til rapportering af klientsikkerhedskopier, der er gemt på Data Domain, bruger DDOS funktionen PCM (Physical Capacity Measurement) eller PCR (Physical Capacity Reporting). Dette gør det muligt at beregne nøjagtig diskbrug af et katalogtræ, samling af mappetræer, MTree eller en samling MTrees. Følgende artikel indeholder en detaljeret forklaring: Data Domain: Ofte stillede spørgsmål

om måling af fysisk kapacitet eller rapportering af fysisk kapacitetTrinnene nedenfor ved hjælp af logføring af Management Console Server (MCS) beskriver, hvordan Avamar bruger PCM-funktionen til at indhente oplysninger om backend-kapacitetsrapporter for sikkerhedskopier, der er gemt på Data Domain:

1. Når en backend-kapacitetsrapport startes, opretter MCS-tjenesten en tråd til at køre rapporten:

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>

2. MCS henter sikkerhedskopierne for den klient eller det domæne, der er valgt i rapporten:

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)

3. Når alle sikkerhedskopier er indsamlet, kalder MC en REST-API til Data Domain for at oprette en komprimeringsmåling:

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

Målingen omfatter sikkerhedskopier af alle klienter:

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

4. Det kan tage et par minutter at fuldføre rapporten, hvor MCS fortsætter med at overvåge målingen fra Data Domain:

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

5. Når målingen er fuldført på Data Domain, modtager MC dataene:

03/31-13:22:18.00806 sun.net.www.protocol.http.HttpURLConnection.getInputStream0

6. MCS afslutter jobbet og indsætter rapportdataene i report_history tabel i MCS-databasen (MCDB). Dette gør det muligt at se rapporterne fra Avamar UI:
