From EDGE:
Different retention on source vs target server is planned for a future release.
(with all due disclaimers about how nothing is guaranteed for future
releases...)

Hallo Robert,
to answer the last part of your question:
"...So if I have for a node a policy (archive) of keeping 365 days and on the
TARGET server I just want to keep 60 days. During the first replicate node
which policy works ? All data for 365 days will be replicate or just the data
for 60 days ? ..."
Some Facts:
Domains are not replicated. If same domain name exits on Target Replication
Server (TRS), it will be used, otherwise the “standard” one will be choosen.
Expiration is always handled by the source replication server (SRS). SRS
informs TRS to delete an expired Object during replication process.
Case 1: backups:
Assume you allow 4 versions on SRS and only 2 versions on TRS:
Replication will replicate all 4 versions (you can check with q occ and from
“backups” table on TRS).
“Half-Failover: If you change to the TRS with –forcefailover (or with a DSM
optfile pointing to TRS (same result)) , you can restore all 4 versions from
TRS.
“Full-Failover”: Now, you do a “remove replnode <node>” on TRS :
replication is removed (replstate=none and replmode=none)
You still !! can restore 4 versions on TRS: Only if you do a new BACKUP
(which now is possible), a “rebinding” will be done, forcing the policies of
the TRS to become effective (2 versions only).
Case 2: archives:
As long as the SRS is the owner, you will have RETVER=365 for all replications.
But if you change ownership of your node on TRS (remove replnode <node>), than
RETVER=60 days will become the effective value for your archives. The next
“expire inventory” will expire and delete all archive objects older than 60
days.
Some background for archives: Archives are never rebound (in terms of
active/inactive objects), because we have no versioning.
Archive copies remain bound to the MANAGEMENT CLASS specified, when you
archive them (only if the MG does not exist anymore or the archive CP is
deleted it will be rebinded to the default MG (or the grace period if the
default MG is not available).
Attention: pls check also the retention for your archive directories (may be
you are using also ARCHMC=)
So the final message is: keep SRS and TRS policies the SAME for a node to
replicated!.

Hi Michael
Thank you very much for the information ..... make more sense now.
Your link is very helpful too ..
I have just need another clarification about the policy retention , if they
are not the same in SOURCE and TARGET servers . I mean that I want to keep in
TARGET server less versions (type backup) or last days (type archive).
To make simple in source F.S (default) - Node (default) - server (ALL_DATA)
So if I have for a node a policy (archive) of keeping 365 days and on the
TARGET server I just want to keep 60 days.
During the first replicate node which policy works ? All data for 365 days will
be replicate or just the data for 60 days ?

Hallo Robert,
interesting questions:
As I'm currently documenting and testing as well the node replication feature
(see
http://www.mm-it.at/de/TSM_Node_Replication_CMDs_Options_at_a_glance.html)
I try to share my current knowledge:
Domain Change on Target Replication Server:
If you move a node to a different domain on the target, replication will move
it back
Means, that if I change a domain for the node on the target replication server
AFTER a successful replication and then try another replication to the same
node ,
the domain for the node on the target server changed back (without a
message!!!) to the original one.
replstate=purgedata
E.g. if you do: de fi node-name * replstate=purgedata datatype=backup,
then:
è Backup rule data is then set to state "Purge Data": à see q fi
node * f=d
è During next replication the objects will be deleted on the target server (see
message during replication) and
è The replstate for the filespace will be set to disabled
You can see the status of the deleted objects later on with q replicaton
node-name <processed=xx> f=d
What remains to be clarified for me: also with "update node" you have the
"undocumented" option of purgedata for the replstate, but I can not see any
"purge data" status
è My be TSM development can clarify - thanks
Expiration:
The Source server instructs target to delete objects during replication

Betreff: Tsm replication 7.1
Hi to all
Long time ago I test the replication feature for DRM purpose. Now I wanted to
implant it between two TSM servers version 7.1 and O.S Windows 2008 R2 64B.
I have some questions:
· The command replicate node if no domain exist in the TARGET server
as in SOURCE server , put the node under the domain STANDARD.
My question is after it can I update the node to a different domain (created on
the TARGET server but in the SOURCE server is not exist) , and in the next
replicate node it will go to this domain and not to STANDARD ?
· In SOURCE server in the command "update fi" it is an option
replstate=purgedata" I don't quite understand the purpose ?
· When replicate node with type ARCH have in ARREPLRULEDEFAULT
the options : ALL_DATA , ALL_DATA_HIGH_PRIORITY , DEFAULT , NONE . I
am using ALL_DATA
If I have a node in the SOURCE server with archive copygroups rentention of
360 days and in the TARGET server in the archive coypgroups retention of the
domain STANDARD is 90.
My question what happen in the replicate node to the TARGET server when no
same archive copygroups retention ? Did all data will be replicate and only
after running an expire inventory in the TARGET server only the data for 90
days will remain ? or already during the replicate node only the data for 90
days with will replicate ?
T.I.A Best Regards
Robert
