Yes, every time a backup operation is run files are bound/rebound to
management classes. Remember that as the "file" percolates up through
the include/exclude list if it doesn't have a "match" or if its
"match" doesn't have a management class specified it takes the
default.
When a file is "rebound" to a new management class, ALL COPIES
contained within the adsm server are rebound.
In your below problem say...

This is OK, no matter where you move the data within the adsm server
the file will retain their management class characteristics
> 3. issue move data opticvolume stgpool= tape storage pool
same as with #2 ***BUT*** if you now, on your client, rebind the
client files to some other management class... IT DOESN'T MATTER where
the old copies are on the adsm server, they are rebound AND EXPIRED
based on the most recent client/server processing.
If you wish to take long term "no limit" / never expiring versions of
client data... use "archive" and if you don't want to push that extra
data across the network you could perform an "EXPORT" of say the
client's active data and then (using the right options) you could
import that client & its data at a later time .
OK, I've probably made this about as clear as mud... sorry.
Maybe this will help...
If you want to keep something for "A PERIOD OF TIME (duration)" then
you have to ARCHIVE it, otherwise "versioning" determines the life of
the file on the adsm server... You could set a "no limit" versioining
but there ain't enough tape in the world for that AND as soon as the
active version of a file binds to a new management class... so go all
the inactive versions ! ! !

Thank you very much for your answer.
Still some things are not clear for me...

Is the file bound to a management class at the time of the backup operation,
through the include/exclude list file, isn't it?

Next day I return to my day by day management class and I make backup
operations on the same files/directories, but this time they will have the
rules specified in the copy group of my management class, management class
which is different than mgmt class mentioned above ( that " no limit " class
)?!
Do this mean that I rebound my files after the backup is finished?

Ok, let's say I choose to move my data.
Are this the rights steps?
1. Make the backup with the "no limit" mgmt class
2. issue move data volname stgpool=another storage pool ( optical - sice i do
not have disk space
3. issue move data opticvolume stgpool= tape storage pool
Thank you for your help.
