Refer toyourExchangeServerdocumentationforthisinformation.Some commonlyusedstrategiesaredescribedbelow.

v

Ifyouchoosea strategythatinvolvesincrementalordifferentialbackups,

circularloggingmust bedisabledonthestoragegroupsoftheExchangeServer. v Youshouldnotmixincrementaland differentialbackups.Differentialbackups

Incremental backupsperformedafter differentialbackupscontainallchangessince thelast incrementalorfullbackup.Restoresaremorecomplicatedwhenusinga mixed strategy.Youneedtodetermineonanindividual basiswhichtransactionlog backups(differentialorincremental)torestorealongwiththefullbackup. v IfyouplantouseVSSBackups,youshouldcontinuetouseLegacyBackupsas

v Incrementalanddifferentiallegacybackupscannotberestoredwith fullorcopy

Thisapproachisbestfor ExchangeServersthatarerelatively smallbecauseeach backupcontainsenough datatorestoretheentirestoragegroup.Eachbackup takes longertoperform,but therestoreprocess isthemostefficientbecauseonly themostrecent(orotherappropriate)fullbackupneedstoberestored.

Full

backup

plus

incremental

backups

Thisstrategyiscommonlyusedwhen thenormalbackupwindowornetwork capacitycannotsupporta fullbackupeachtime.Insuchcases,aperiodicfull backupfollowedbyaseriesofincremental backupsallowsthebackupwindow and networktraffictobe minimizedduringpeakusage times.For example,you canperform fullbackupsontheweekendandincremental backupsduringthe week.Thefullbackupscanbedone duringlowusagetimeswhena largerbackup window andincreasednetworktrafficcanbe tolerated.The restoreprocess

becomesmore complex,however,becausea fullbackup,aswellassubsequent incremental backups,mustberestored.Inaddition,transactionswithinthelogs must beapplied whichincreasesprocesstime.Asaresult,themoretransactions applied, thelongertherecoveryprocess.

Ifyouusethis backupstrategy, youmust decidewhethertheTivoliStorage Manager storagemanagementpolicies aremodified,toensureallincremental backups arestoredtogetherontheTivoliStorageManagerserver(collocated).This helpsimproverestoreperformancebyreducingthenumberofmediamounts necessary forrestoringa seriesofincrementalbackups.See“HowTivoliStorage Manager serverpolicyaffects DataProtectionforExchange”onpage16formore information.

Thisprocessprovides aneasierrestorethanthefullplusincrementalbackup. This approach mightbeusefulif yourbackupwindowandnetworkcapacitycan handlethebackupof alltransactionlogs thataccumulatebetweenfullbackups.

Thisisbecauseitrequiresthetransferofonlyonedifferentialplusthelastfull backuptoaccomplisha restore.However, thesameamountofdatamust be transferred inthedifferentialimage,asintheseries ofincrementalbackups. Therefore,afullbackupplusdifferentialbackuppolicyincreasesnetworktraffic and TivoliStorageManagerstorageusage.Thisassumesthatthedifferential backups areperformedwith thesamefrequencyastheincremental backups.
