That is correct.  The kludge I use to backup directories (rather than FSs) 
with ACLs is to run a script before the backup.  The script, in essence, 
does 'getfacl -R $DIR_WITH_ACLS > /home/amanda/$DIR_WITH_ACLS.acls.txt'.  
In the event you need to restore the directory, put the data back, and 
then do 'setfacl --restore=$DIR_WITH_ACLS.acls.txt $DIR_WITH_ACLS'.  
Of course, I also make sure that /home/amanda is getting backed up -- 
otherwise put the ACL file somewhere else.

If I have a whole FS that's not too big and needs ACLs, I'll often format 
it XFS and use xfsdump for just this reason.
