Hello Freddy,

In order to limit memory resources for a PRM group, you use the memory cap field of the group's corresponding memory record. Then all processes that run with that PRM group are subject to that specified upper limit. In your case, you would want to make sure that only processes associated with the backup are assigned to that particular PRM group through either user or application records.

#!PRM_MEM:{PRMID|GROUP}:SHARES:[CAP]:[SUPPRESS]::[[IMPORT]:[EXPORT]:[LOCKABLE]]

For example:
#!PRM_MEM:backup:10:40:::::

This give the PRM group 'backup' a guaranteed 10% of available memory while capping its memory consumption at 40% of available memory. You would need to figure out what % amount corresponds to 400 MB on your system.

Hope this helps.
