The PreserveDBOnExit setting prevents the journal from being deleted when 
the journaled file system the setting is specified for (in the journal 
daemon configuration file) is taken offline, such as when
the journal daemon is stopped and restarted.

If the journal is empty when the journal daemon starts of course the 
backup will be full incremental (and this full incremental must 
successfully complete before the journal can be used again).

The only method of forcing a full incremental without taking the journal 
offline is to use the NOJOURNAL client option on the backup command.

Using this option also has the advantage of keeping the journal intact 
while the non-journal backup is running.

Unfortunately this option may only be specified as a command line argument 
(it isn't valid in the client options file) so the only method of forcing 
periodic full (non-journal) incrementals
is to define a separate schedule to run the backup with the NOJOURNAL 
option.

Hope this is helpful ....

Hi Steve,

The PreserveDbOnExit  flag is already set.  Thus we *NEVER* do run FULL 
INCREMENTAL BACKUPs.  Now we see that we occasionally have newer versions 
of files that never actually got detected by the journal.

What I want is to - say once every month, actually *FORCE* a FULL 
INCREMENTAL BACKUP of a given node, on such a setup, without changing the 
actual COMMAND specified in the client schedule.

Stay tuned, could take a while however...

Regards,

Luc

Luc,

There is a flag you can set that stops the database from being invalidated 
by a stop of the Journal service.

I have usually set this because when journaling is required, an arbitrary 
full scan is usually not wanted.

Hi Marc,



Thanks for the feedback.



I forgot to state that the Windows admins have historically put in place a 
batch file to take backups.

It's been forked into more that 50 versions since.

None of which forward any of its cmdline arguments to the actual "dsmc i" 
command.



I've since been looking at the "Journal-based backup" section of the BA 
client install and users guide.

It lists about 7 possible ways to invalidate the journal db.

Most are not applicable to steady state (changed node, fs, server)

However, I see 2 ways that would work in my universe :

1.      "A policy changes occurs (new policy set activation)"

2.      "The journal service is not running"

3.      The journal service is stopped or started for any reason, even if 
it is restarted because the system is rebooted.

I think I'll focus on the 2nd way.

Looking into using DSMCAD to run "dsmcutil stop /name:"TSM Journal 
Service"" and "dsmcutil start /name:"TSM Journal Service"" as one-shots.



I'll keep you guys posted.



Still open to other approaches.



Regards,



Luc

Hi Luc,



You should be able to define a client schedule with "option=-nojournal"



So you would have two schedule.  The current one, plus one that 
periodically does -nojournal.

Thanks,

Marc...

Greetings everyone,



Our shop is TSM 717000 on AIX, with lots of Win BA clients v7164 with 
journaling enabled.



In a restore test of a Windows node, we found that a file that was changed 
in 2017 was never backed up.

We thus kept the previous iteration (circa 2016) as active in the actual 
node data.



We were led to journaling FAQ at

http://www-01.ibm.com/support/docview.wss?uid=swg21681523

So, now we are looking to implement the recommended "periodic FULL 
INCREMENTAL BACKUPS".



We have no actual access to the Windows clients, except for DSMCAD...

Thus I thought of doing a periodic rotation of node clopt on the 
server-side, however it seems that the NOJOURNAL option is only valid on 
the dsmc command-line.



How have you guys gone about implementing this ?
