It's "normal". Especially for the backup process with default VMM setting.
As long as number of free memory pages is above 'minfree' (see vmtune command),
AIX keeps allocating free memory for computation or file cache (in this case),
unless you turn on strict maxperm.
And file cache pages dont' go away until files are removed of umounted.
If you don't understand what I say, go look at 'vmtune' command and
read AIX Performance Tuning Guide.
