I have a client running BE 8.6 with a 20/40 DAT drive backing up 14GB of data. The past 2 weeks, they keep getting a failure with there backup. The log shows all data backed up except the System State (last part) and never does a verify. After the D drive is backed up, the following message appears "The media provided to continue the backup already contains data from one or more sets created during this operation. The operation can not be continued." The tape is then ejected and needs to be manually canceled.
I have tried moving all tapes to the Scratch Folder and do a full erase and I still get the same message. Please guide me as to what could be going on.
Thank you,
Rich
