I am using Backup Exec 8.5 rev 3572 software to backup my data daily, this morning I got an OFO error telling me that device C wasn't initialized and thus the backup wasn't successfully completed. The exact message was: "OFO Initilalization failed Device:C:" I read the log file and it seems that the backup was completed successfully as well as the verification process went to 100%, after that the progress switched to on-hold and later switched to failed with unknown percent completed. The Error code for this error was OFO Error: 0x41. If anyone has any input on this I would greatly appreciate it. Thank you.
