  • TSM 7.1.1 PERFORMANCE ENHANCEMENTS NODE REPLICATIONS

    RECONCILIATION

    3

    Prior to TSM 7.1.1, replication has always done a reconcile (Abgleich)

    Compares complete list of files between the source and target server

    Used to synchronize the source and target servers

    Reconcile in TSM 7.1.1- Examines entire list of files in a file space (much like pre 7.1.1)

    Used during the initial replication between 7.1.1 servers

    Once reconcile completes, change tracking processing takes over during the next replication

    Automatically runs following a database restore on the source or target server

    Can run manually using REPLICATE NODE FORCERECONCILE=NO|YES

    Synchronize source/target files - used like an audit

    Resynchronize source/target files if the db is regressed (other than DSMSERV RESTORE DB)

    Restartable remembers where it left off if cancelled or after some catastrophic server event

  • TSM 7.1.1 PERFORMANCE ENHANCEMENTS NODE REPLICATIONS

    RECONCILIATION

    4

    Change Tracking in TSM 7.1.1 eliminates need to query target server for its list of files

    New and change files are assigned a change identifier: when its stored & when meta data is updated

    Replication only processes files with a change identifier incremental replication

    Replication picks up where the last replication left off

    Improves performance for fs with lots of files

    New Replication rule that enables replication based upon Domain

    In addition to current replication by Server, Node and Filespace

  • TSM 7.1.1 - NODE REPLICATION WITH DISSIMILAR POLICIES

    5

    Description: Decouple target from source server policy, allowing target server to manage replicated

    files via its own policy

    Benefits: Maintain more or fewer versions of replicated backup files between the source and target replication servers Retain replicated archive files for more or less time on the target replication server If fewer versions of files are kept or retained for less time on the target server, the amount of target server

    storage required can be reduced

  • TSM 7.1.1 - NODE REPLICATION WITH DISSIMILAR POLICIES

    6

  • TSM 7.1.1 - NODE REPLICATION WITH DISSIMILAR POLICIES

    7

    Server Support: Different policy for retention time & number versions can exist on

    primary & target server

    On source server first run VALIDATE REPLPOLICY Default is to disable dissimilar policies If disabled, the serves will act as they do today and honor the source servers policy

    On source server SET DISSIMILARPOLICIES server on Once enabled, target server is notified during the next replication VEREXIST, VERDELETED, RETEXTRA, RETONLY, RETVER, RETMIN will impact what is kept Expiration then runs independently on each server target server runs expiration

  • TSM 7.1.1 - NODE REPLICATION WITH DISSIMILAR POLICIES

    8

    Backup data: VEREXIST, VERDEL, RETONLY, RETEXTRA control when a backup is deleted

    Archive Data: Only RETVER controls the length of time a file is retained for

    Space Management Data: Retains the same behavior with or without dissimilar policies enabled

    VALIDATE REPLPOLICY

    Must be ran prior to enabling dissimilar policies

    Displays differences in policy settings for all nodes that exist on both source and target servers

    Can be used to validate policy settings are correct, or to debug policy related issues

    If no server is specified, defaults to current replication target server

  • TSM 7.1.1 - NODE REPLICATION WITH DISSIMILAR POLICIES

    9

    SET DISSIMILARPOLICIES Issued on source server to enable dissimilar policies for a specific target server

    Must run VALIDATE REPLPOLICY for the given target server before this can be enabled

    QUERY REPLSERVER New field added to tell you if Dissimilar Policies is enabled for target replication server or not

    Rebinding of Files on the Target Replication Server In 7.1.0

  • TSM 7.1.1 - NODE REPLICATION WITH DISSIMILAR POLICIES

    10

    Changes for Expiration

    Source server If dissimilar policies enabled, source server holds onto a file until it has been replicated to the target

    Files that have not yet been replicated, must be replicated before they can expire on the source

    Files that have been updated ( active inactive or inactive expire immediately ) must be replicated (updated) before they can expire

    Bypass this requirement temporarily by updating the node or filespace replication rule to NONE

  • TSM 7.1.1 - NODE REPLICATION WITH DISSIMILAR POLICIES

    11

    Changes for Expiration

    Target Server All files are now deleted by expiration on the target server

    Replication process no longer directly deletes files, instead deferred until expiration processing on the target server

    The exceptions are group data and hsm data: These are still deleted during replication processing

    If dissimilar Policies is enabled, the targets policy take affect as data is ingested into the server

    This is exactly the same way a client backup is handled

    As a file comes in, if there is an extra version, it is set to be expired

    If dissimilar Policies is not enabled, the data's state is copied from the source serve

    If it is active on the source, it will be active on the target

    If it is inactive on the source, it will be inactive on the target

    When expiration runs, it will delete files as it always has

    Files that are expired will be removed whether dissimilar policies is on or off

    Dissimilar Policies just dictates how files are set to expired during the ingest of the data

    ARCHIVE data that has passed its retention data is only expired on the target if dissimilar policies is enabled

  • TSM 7.1.1 - NODE REPLICATION WITH RECOVERY OF DAMAGED FILES

    12

    Description: Retrieve files that have been damaged on the source server from replication target server Benefit: Assist with local recovery of files that have been damaged on the source server

    Replaces damaged files with good copies that have been replicated

    Includes files on volumes that have been updated as destroyed

  • TSM 7.1.1 - NODE REPLICATION WITH RECOVERY OF DAMAGED FILES

    Scenario:1) Server A replicates data to Server B2) Storage pool volume or files on Server A is lost or data is otherwise inaccessible3) Storage pool volume or files is restored from Server B to Server A

    Server Support: Must enable: SET replrecoverdamaged on

    Additional step in replication process, if source server has damaged files in a file space

    being replicated

    Notifies the target server to resend them at the end of the replication

    When source replication ends, the target would start process to resend the damaged files

    Damaged files are deleted and replaced with new copies, retaining original insertion date

    New parameter on REPLICATE NODE command: RECOVERDAMAGED=YES|NO|ONLY

    RECOVERDAMAGED=ONLY will not do replication, it will only recover damaged files

    New column in Replicated_Objects tracks damaged files
