Problem with backup

[pichi]

hi everybody, i have a "little" problem, i can't make backups on my mail server, my server is dell poweredge 2650, and the backup is external Dell Power Vault 110T, i use tapes LTO Ultrium 200G compressed. my problem is that i get this error: Error with sense data info fld=0x1ad16 current st09:00 sense key medium error, although sometimes i can make backups, i have tried with little directories that have a size of 2Gb, but i get the same error, so i don't think is the data, because is static data, no one is reading mails, so what else could be??, the tapes not, because i use many, and it's the same, maybe the power vault 110T??
any ideas would be apreciated, thanks in advance

Try forum531 for backup issues. What software are you using and what commands?

Have you tried a cleaning tape on the power vault? Could be dirty heads. Have you tested a new, empty tape to see if you can make a backup?

yes, i have tried that, when i use the clean cartridge i usually can make backups, but then after that backup i want to make another and get the same problem.
