Data Domain 5le systems:

, The administrati(e 5le system /called dd(ar0 – dd(ar

, The storage 5le system /called %tree0 – bac'up /datacol<0 Data Domain System Protocols:

, +FS – +et!or' 5le system /+FS0 clients can ha(e access to Data Domainsystem directories and %trees7 , "IFS – The "ommon Internet FileSystem /"IFS0 clients can ha(e access to Data Domain system

directories and %trees

, VTL – The (irtual tape library /VTL0 protocol enables bac'up applications to connect to and manage Data Domain system storage as i* it !ere a tape library7 $ll o* the *unctionality generally supported by a physical tape library is a(ailable !ith a Data Domain system con5gured as a VTL7 The mo(ement o* data *rom a system con5gured as a VTL to a physical tape is managed by bac'up so*t!are /not by the Data Domain system07 The VTL protocol is used !ith Fibre "hannel net!or'ing7

, DD oost – The DD oost protocol enables bac'up ser(ers to communicate !ith storage systems !ithout the need *or Data Domain systems to emulate tape7 There are t!o components to DD oost: one component that runs on the bac'up ser(er and another component that runs on a Data Domain system , +D%P – I* the VTL communication bet!een a bac'up ser(er and a Data Domain system is trough +D%P1no Fibre "hannel /F"0 is re3uired7 Ahen you use +D%P1 all initiator and port *unctionality does not apply7

Foreign Dis's – The *oreign state indicates that the dis' contains (alid Data Domain 5le system data and alerts the administrator to the presence o* this data to ma'e sure it is attended properly7 This commonly happens during chassis s!aps1 or !hen ne! shel(es are added to an acti(e system7

Lin' *ailo(er is supported by a bonding dri(er on a Data Domain system7 The bonding dri(er chec's the carrier signal on the acti(e inter*ace e(ery H79 seconds7 I* the carrier signal is lost1 the acti(e inter*ace is changed to another standby inter*ace7 $n address resolution protocol /$#P0 is sent to indicate that the data must o! to the ne! inter*ace

–G%anage VL$+ and IP $lias:

VL$+ and IP alias net!or' inter*aces are used: , For net!or' security

,To segregate net!or' tra8c ,To speed up net!or' tra8c ,To organi6e a net!or' ;o! It Aor's:

I* youJre not using VL$+s1 you can use IP aliases7 IP aliases are easy to implement and are less expensi(e than VL$+1 but they are not a true VL$+7 For example1 you must use one IP address *or management and another IP address to bac' up or archi(e data7 Kou can combine VL$+s and IP aliases7

Data %anagement: –GSnapshot:

Snapshot location: datacol<bac'up

ex: datacol<bac'upaustin7snapshot  datacol<bac'upscla7snapshot !here1 7snapshot is a directory

, #eplication donJt replicate snapshot o* a (olume1 it has to be manually con5gured *or replication7 –GFast "opy:

$ *ast copy copies 5les and directory trees o* a source directory to a target directory on a Data Domain system7 Kou can use the *ast copy operation to retrie(e data stored in snapshots7 Fastcopy ta'es space /itJs li'e a clone07

–G#etention Loc': – Licensed *eature

- #etention loc' is an optional1 system-licensed so*t!are *eature that enables organi6ations to protect their data in non-!riteable and non-erasable *ormats *or a speci5ed length o* time1 up to MH years7 #etention loc' protects against:

 $ccidents and user errors  %alicious acti(ity

– Data !hich has been loc'ed using the retention loc' *eature ma'es the data !riteable and non-erasable7 Files cannot be modi5ed e(en a*ter the retention time *or the 5le expires7 The retention period o* a retention-loc'ed 5le can be extended but not reduced7

- In order *or a 5le to become loc'ed !ith the retention loc'1 the 5leJs access time /called Eatime0 must be set to a *uture date that is beyond the minimum retention period con5gured on the Data Domain system7

– The act o* setting the atime is the signal to the Data Domain system to loc' the 5le7 $s soon as this (alue is set1 the 5le is loc'ed and cannot be deleted or modi5ed be*ore that date7

Data saniti6ation:

- Data saniti6ation is sometimes re*erred to as electronic shredding

– Aith the data saniti6ation *unction1 deleted 5les can be o(er!ritten using a DoD+IST compliant algorithm and procedures

– It remo(es any trace o* deleted 5les !ith no residual remains pre(enting normally deleted data *rom being reco(ered7

Data &ncryption:

- $lso called inline data encryption

– Protects data on a Data Domain system *rom unauthori6ed access or accidental exposure – #e3uires so*t!are license

– Ahen data is bac'ed-up1 data enters (ia +FS1 "IFS1 VTL1 DD oost and +D%P Tape Ser(er protocols7 It is then:

 Segmented  Fingerprinted

 Deduplicated /or globally compressed0  2rouped

 Locally compressed  &ncrypted

Important – encryption at a more granular le(el is not possible7 Cnce enabled all the i ncoming data !ill be encrypted7

File System "leaning:

- "leaning reclaims physical storage occupied by expired data7 For example1 as retention periods on bac'up so*t!are expire data1 old bac'ups are remo(ed *rom the bac'up catalog7 Space *rom expired bac'ups becomes a(ailable only a*ter a system cleaning process reclaims the dis' space7

- Ahen application so*t!are expires bac'up or archi(e data1 they are deleted in the sense that they are no longer accessible or a(ailable *or reco(ery *rom the application7 The data is not deleted immediately it is remo(ed during a cleaning operation7 In the case o* retention loc'1 expired 5les !ill not be deleted until the retention loc' period ends7

- Delta compression is a global compression algorithm that is applied a*ter identity 5ltering7 The algorithm loo's *or pre(ious similar segments using a s'etch-li'e techni3ue that sends only the di4erence bet!een pre(ious and ne! segments7

- Delta compression reduces the amount o* data to be replicated o(er lo!-band!idth A$+s by eliminating the trans*er o* redundant data *ound !ith replicated deduplicated data7 This *eature is typically bene5cial to remote sites !ith lo!er Data Domain models

- In a typical bac'up en(ironment using in-line deduplication1 client data is sent to a Data Domain system !here the data is identi5ed in segments7 These segments are identi5ed to be uni3ue data or duplicate segments7 I* they are uni3ue1 they are compressed and !ritten to the storage subsystem on the Data Domain7
