HowdoesDeduplicationworkwithRemoteReplication?
CommVaultSimpanasoftwareisbuiltfromacommonsetofre‐usableserviceswhichhavebeenoptimizedfor
moderndatamanagement.Theseincludeadvanceddatabackupandrecovery,archive,encryption,compression
anddeduplication.Eachindividualserviceandcapabilityoffersitsowncompellingadvantage.Incombination,the
benefitfordatamanagementis
compelling.

Organizationsplanningfordatacentralizationfromremotesitesandsystemsareconcernedwithnetwork
efficiency.Toaddresstheseconcerns,CommVaultSimpanasoftwareoffersafullrangeofcapabilitiesdesignedto
ensurethatonlythedatawhichmustbereplicatedissentacrossWideAreaNetworkconnections.Bycombining
advanced
capabilitiesforbackupandarchivetogetherwithcompression,encryptionanddeduplication,
CommVaultSimpanasoftwareprovidesbetterefficienciesfortransmissionofanytypeofdataacrossWAN
connectionsthanisotherwiseachievable.

Theeffectofefficientbackup:CommVaultSimpanabackupsoftwareincludescapabilitiesforselecting
incrementalanddifferentialdataforprotection.
SyntheticFullcapabilitiesmakethisevenmoreefficient,andis
oftensuitableforprotectingdataacrossWANconnectionswhentherateofchangeonremotedataislow.

Theeffectofarchive:CommVaultSimpanaarchivecapabilitiesfurtherreducetheburdenondatabackupby
removingstaticandlessfrequentlyused
datafromprimarystores.Removingthisdatatosecondarystoragenot
onlyfreesuptheprimarydiskandspeedsapplicationperformance,italsoreducestheamountofdatathatmust
bebackedup,preservednightlyorweekly,androtatedoffsitefordisasterrecovery.

Theeffectofcompression:Dependingonthe
typeofdata,compressionalgorithmscanoftenreducethesizeof
thedatabeingsentovernetworks–sometimesmorethandeduplication.CommVaultSimpanasoftwareoffers
theabilitytocombineuseofcompressionwithdeduplication,formaximumnetworkefficiencyforalltypesof
data.

Theeffectofencryption:CommVaultSimpana
softwareincludesadvancedencryptionalgorithmsincludingAES
256,Blowfishandotherpopularencryptionmethods.Theseareofferedforuseincombinationwithdata
compressionanddeduplication,toensurethatdatasentacrossWANconnectionsdoesnotpresentasecurityrisk.

Theeffectofdeduplication:CommVaultSimpanaoffersFileDeduplication
capabilitiesforfile,documentand
emailattachmentdeduplication.Whenappliedtodataatremotesites,deduplicationremovesanyduplicatedata
beforethatdataissentonWANconnections.Uniquelydesignedforusewithcompressionandencryption,
CommVaultSimpanadeduplicationoffersbetterefficienciesfortransmissionofanytypeofdataacrossWAN

connectionsthanisotherwiseachievable.
