Hi Steve, thanks for answering... Yeah, the destination is tape, i see on StorageAgent console the connection to server and opening tape, during the backup I see the bytes increasing on "Backup by LANFree: " (but, this value is ALWAYS lower than the value of normal backup... i don't know if this is normal). VALIDATE LANFREE node policyset shows me that the node is capable to LANFree backups.
During the backup (using webclient interface) I can see two speeds, well.. A screenshot of backup report is at link: http://img18.imageshack.us/img18/9278/backupz.jpg The screenshot is in portuguese but I think is easy to you guess what is each value... Time: 5:45 Hours Size: 181 Gb No compression Rede == Network Agregada == Aggregate, combination... (not sure how TSM show it) Ok, this is what I have... If need more info just let me know.
