Restore - Linux vs Solaris

[Sysadmin]

In the spirit of using Linux as much as possible,  I use my FC4 
server to back my Solaris system.  I have built a custom script that 
reaches across to Solaris system and executes a remote command using 
SSH.  The remote command used is "ufsdump".  The command looks something like
ssh -l user host ufsdump -0uf  - /partition-to-be-backed-up 
|cat  >/destination-directory/filename

Everything is fine til I need to restore from a back up.  It seems 
that I can backup and restore the smaller partitions (in this case 
2.2Gb) without issue. However, when I try to restore a backup for a 
larger partition(in this case 7.6Gb), I am unable restore without 
moving the backup file to a Solaris system.  Once I move the backup 
file to a Solaris system, it seems to work correctly. So the backup 
is being created accurately.

Is there any know differences between the Linux "restore" command and 
the Solaris "ufsrestore" command?  In both cases I am doing an 
interactive restore.
Linux -- restore -vif backup-file.dmp
Solaris -- ufsrestore -vif backup-file.dmp

I would appreciate any insights.
