Hi Jennifer,

The backup always only applies to the filesystem backup, not systemstate. 
You’ll have to change the mode of the systemstate backup to get a full. 

Or use move nodedata to move it all together. 

BTW, you would just have needed to remove the node from the collocation group. 
Nodes not in a collocation group are collocated by node.

Subject: [ADSM-L] Question on Collocation


 I use collocation and I have a node where the System Admin has requested that 
his data from a particular node be isolated on tapes by itself. I created a 
collocation group and have associated this one node with the new group. This 
node had previously been backing up to a different collocation group. I created 
a new Policy Domain and associated the node with it as well. This policy domain 
is set to send the data direct to tape instead of going to our diskpool. I also 
modified the settings on the server to allow this system to have 2 mount points.
 I had the SA launch a "full" manual backup from the GUI - using the "Always 
Backup" option. Here are the problems I am seeing.
 1.       I can see that the system state data when to a tape that was already 
used by other nodes (which tells me the collocation is not working)
 2.       It only mounted 1 tape in a drive while performing the backup
 3.       The metrics at the end showed that it inspected 283 GB of data and 
only transferred 175 GB which means it did not actually perform a full backup.
 Any ideas to help get a FULL backup of this data alone on a single 1 or 2 
tapes and ideally using multiple tape drives to speed things up? (for backup 
and restore)
 Thanks!
 Jennifer
