Question Legato - Networker Recover Performance


I have some concerns about Legato - Networker Recover performance.

To describe our system:

server = IBM pSeries, with Total Storage Cabinet in RAID configuration
system = IBM Unix Aix 5
backup system = Legato Networker 6.1
storage library = IBM Ultrium Tape Library with 2 drives.
storage media = LTO Ultrium 2, 200GB uncompressed, 400GB compressed.
full backup size = 800 GB
full backup rate = 1GB per minute.
full recover rate = 260 MB per minute

Our backup time covers around 13 hours of full backup. We are quite happy about this. But we are not satisfied with the recover rate. At this rate, our recovery would take about 2 days, and many things might happen, power failure, hardware and media failure etc.

Does it really take some time to recover data from backup? Our data consists only of ORACLE database.

We already tests by setting the Parallelism from different values (4, 2, 1), and we got the same results. We only have one client which is the server itself.

I hope someone could give me some answers. Thank you in advance.
