I have been getting this error for the backups, I don't know what to do. We don't have support anymore and have tried checking the KB articles but nothing helps.
We have dell Data domain with CIFS Share, where our application guys dump their backups. From that share, we take backup via Symantec Backup exec and store it in tape. However, after taking backup for approx 10 ~11 TB job fails with this error everytime. Can someone please help or suggest something on this.
I have below errors and exceptions also.
File XXX was not found, or could not be accessed.
File YYY was not found, or could not be accessed.

Would recommend you checkout these TNs if you haven't already - the top one is the most informative:

Additionally I'd be tempted to look at whether tape heads need a clean/cleaning tapes have expired etc.
Also have you tried a backup writing to disk instead of to tape to see if this works, to try and narrow down the problem?
