WhendeployingSysBack5.6inyour environment,understandthatwhenmachines executeremoteSysBack operationswitheachother, allmachinesmust beat the same levelofcode.For example:5.6.0machinesmayonlyexecuteremoteSysBack operations withother5.6.0machines.Machineswith5.6.1(orlater)installed,may onlyperformremote SysBackoperationswithothermachinesusing5.6.1(orlater). RemoteSysBackoperationsinclude,but arenotlimitedto:networkbackups, networkrestores,networkboot,andnetworkinstallation.

2. SelectIBMTivoliStorageManagerforSystemBackupandRecovery. 3. SelectBackup&RecoveryOptions.

Youcanalso accessthismenuusingthefastpath.Todo this,typesmitsb_backup at acommandline.Thefollowingscreenisdisplayed:

Understanding

Incremental

Backups

Incrementalbackups makeitpossibletobackuponlydatathathaschangedsince a priorbackup, significantlyreducingthebackuptimeandmediausage.

Incrementalbackups canbe performedforboth volumegroupandfilesystem backups.

Youperform anincrementalbackupbyindicatinganincremental backuplevel. Thislevelindicates thatonlyfilesthathavechangedsincethemostrecentprevious

levelshouldbeincludedinthebackup. Specifyinglevel0 indicatesthatallfiles shouldbe backedup.Level 0isstillconsideredanincrementallevel;it isthebase for allincrementallevelsthatfollow.

Anynumberof incrementallevelsfrom0through 9canbeused, butusingtoo manylevelscancomplicatetherestoreprocess.

Consider thefollowingincrementalbackupexamples:

Incremental backupof afilesystem isperformed asfollows:

Monday level0 Tuesday level1 Wednesday level2 Thursday level3 Friday level4 Saturday level5 Sunday level6

Inthiscase, ifyouneedtorestoretheentirefilesystem fromthebackup

performedonSunday,youmust restoreeverysinglebackupfrom0through6 in orderto incrementallyreapplythechanges todate.Alwaysrestorelevel0first (when restoringfromscratch)becauseonlylevel0containsa backupoftheentire filesystem.Then,inthecorrectsequence,reapplyeachlevelthatfollows,adding, replacing, andremovingfilesuntil thefilesystemsreturntotheirmostrecentstate.

Incremental backupof allvolumegroups,excepttherootvg group,isperformed as follows:

1stofmonth level0 everyFriday level4 Monday-Thursday level7

Inthisexample,a volumegroupbackupisperformedonthefirstdayof the month. EveryFridaya level4 isperformed, andeveryotherdayoftheweek (excluding SaturdayandSunday)alevel7 isperformed.Becauseonlythreelevels are used,nomorethanthreebackupsneedtoberestored.Ifyouneedtorestore theentirevolumegroup becauseoffailure,therestoresequencewouldbe: 1. Restore level0.

2. Restore themostrecentlevel4ifa level4 wasperformedsincethelastlevel0. 3. Restore themostrecentlevel7ifa level7 wasperformedsincethelastlevel4

orlevel0.

Note: Usecarewhencombiningbothvolumegroupand filesystemincremental backups.An incrementalvolumegroupbackupisidenticaltoperformingan incrementalbackupofeachindividuallogicalvolume andfilesysteminthe volumegroup.Therefore,afterperformingavolume grouplevel0 backup, youcanperform otherincremental backuplevelsforspecific filesystems.If alevel0backupofa filesystemisperformedafter alevel0ofthevolume groupcontainingthatfilesystem,anyhigher-levelincrementallevelsfor thatfilesystemareapplied tothemostrecent(filesystem)backup.

For volumegroupincremental backups,an entirelogicalvolume isincludedifany part ofthelogicalvolume haschanged.Ifnodatainthelogicalvolume had changed,thelogicalvolumeisnotincludedinthebackup.

Understanding

Pull

Backups

PullBackupshelpyoucentrallymanageyourbackups byenablingyoutoinitiate, and therebycontrol,backupoperationsfroma singlelocation.Youcanfurther automate thiscentralmanagementof backupsusingtheSysBackScheduling and ScriptingfunctionsdescribedinChapter20,“ScheduledBackupsand Scripts,”on page20-1.

Themachine that“pulls”thebackupiscalledthe“initiator”whilethemachine thatisbackedupiscalledthe“backupsystem”.Themachine thatreceivesthat backupdataiscalledthe“datadestinationsystem”.

Pullbackupenablementrequires, notonlyRemoteServicesconfiguration, butalso RemoteCommandAccessconfiguration.TheRemoteServicesconfiguration enablesthedatatobesentacrossthenetworkfromthebackupsystemtothedata destination machine.TheRemoteCommandAccessconfigurationenablesthe initiator systemtopullthebackupsfromthebackupsystem.

PullBackupscanbedone inatwo-wayorthree-waymanner.Whentheinitiator system isalso thedatadestination system,thisisatwo-waybackup.Whenthe initiator systemisa differentmachinethanthedatadestination system,and differentthanthebackupsystem,this isa three-waybackup.

Notethatforthree-waybackups,RemoteServicesmust beconfiguredbetween MachineA,thebackupsystem,andMachineB,thedatadestination.Remote CommandAccessmust bealsoconfigured betweenMachineA,thebackupsystem, and MachineC,thebackupinitiator.FormoreinformationonconfiguringRemote Servicesand RemoteCommandAccess,seeChapter8,“RemoteServices,”onpage 8-1.
