Hi,
this question to mqs expert people having already done backup (and restaur) of the FS mqs (/var/mqm, /opt/mqm) just before we are going to do save mqs before upgrade to 5.3:
- i have been said that the best way to save (then to restaur) this filesystems is to use the copy (cp) utility with the ' -rp' options
(cp -rp /var/mqm /MQS-SAVE/var_mqm) to be able to copy:
+ the dty and all its files including any subdirectories
+ to preserve the owner & group IDs, permissions modes, modif & access time
is that right?
some other consideration?
thanks for help

can we take a backup when the Qmgr is up and running?
The safest way I use is to shutdown the Qmgr and use any OS backup ulility to save the configuration.
cp,tar,cpio anything,doesn't matter!! |

You can NOT take a backup against a running queue manager.
(The required logs are in a constant state of possible flux/change.)

unless I am mistaken you could always use the saveqmgr script to create a backup buildfile of the Objects in the existing MQManager (even when the MQManager is running).
/usr/mqm/BIN/saveqmgr -m QMGrName -f filename
Then upgrade and use that file to populate the MQManager:
runmqsc MQMgrName < filename > filename.out
Or if you feel it is absolutely necessary you can back up the /var/mqm filesystem/directory with the following command:
tar cvf /whereever/youwant/tosaveit/MQ-SAVE.tar /var/mqm
but I guess if you want you can stop the MQManager/s and use
cp -rp /var/mqm /whereever/youwant/tosaveit/MQ-SAVE
as long as there is plenty of space in FileSystem you plan to place the MQ-SAVE file has plenty of space.
But all in all I am thinking you may be over or under thinking about this on a technical level.
