Federico,

Here's a cut and paste out of my personal documentation. Hope this helps,

Restore procedure:
- Compressed dumps may be restored with the command:
  gunzip -c xfsdump.gz | xfsrestore -i - /restore/path

  This is useful to restore files that a user may have deleted, for example.

- For example, a user's home directory can be restored interactively
  by using the command:
  
  gunzip -c /mnt/backup/home/home_xfsdump0.gz | xfsrestore -i - /home

  Then by selecting the user's home directory with "add", followed by the 
"extract" command.

- Full restoration may be performed by using the -r
  (Cumulative) option in xfsrestore. Read xfsrestore man page
  thouroughly before attempting to do this!

Note: Be sure to only restore the backup dumps up to the date you wish to 
restore to!  For example, if you want to restore to Tuesday, only restore 0, 1 
and 2 - not anything else!


hope this helps,

Ian.
