Hi Rodrigo,
export/import or implementing a complete new server to server communication
can be quite time consuming, especially when you need a fast solution.
Why not install a temporary client machine with enough HD space and restore
all needed data right in front of the ADSM server that has the data in its
pools. Then get the temporary machine to the location that has the data loss
and just do a filecopy to the original/rebuilt server hardware.

Good luck!

Regards
Michael
