If you are creating the save set, can you make a series of smaller save 
sets? I tend to make a lot of little save sets like one per file or one 
per directory so it's quicker to do a restore of a particular file 
rather than having to restore a large save set just to get one file that 
was deleted.

Some other posts suggested using zip but I believe zip has an  upper 
limit of ~2GB.

File attributes for a save set can be manually restored by using set 
file/(attr=rfm:fix,lrl:32256) where the 32256 is obtained from a 
dir/full of the save set looking at the record format. We have copied 
save sets to a Linux box and then used bzip to compress them enough to 
fit on a Blu-Ray disk and needed to do that to restore the save set.
