XFS restore don't restore

[Fugazzi99]

Hi everyone,
I think I hit a problem of xfsrestore again.
I had some problems with my HD so I had to change it, after that I tried 
to restore from the last dump of yesterday.
I made it with the last xfsrestore/dump 3.1.2 but when I try to restore 
it with xfsrestore 3.1.0 from sysrescuecd I got for the root filesystem:

xfsrestore: using file dump (drive_simple) strategy
xfsrestore: version 3.1.0 (dump format 3.0) - type ^C for status and control
xfsrestore: searching media for dump
xfsrestore: examining media file 0
xfsrestore: dump description:

xfsrestore: restore complete: 4 seconds elapsed
xfsrestore: Restore Summary:
xfsrestore:   stream 0 /root/sdb/dump/old/backup/dump/root.dump OK (success)
xfsrestore: Restore Status: SUCCESS

It restored only the directory tree and nothing else, also for the home 
directory I got this messages and nothing got restored.
I had 6 backups on different drives but they were all made with the last 
dump 3.1.2 and so they are all unaccessible now.
Basically I'm a little fucked if I will not be able to restore one of 
them I have lost all.
Is it a know incompatibility with different restore versions or I'm lost?

Thanks for the help,
Fugazzi
