File to tape task hanging

[pawell]

A couple weeks ago strange issue starts to happen sometimes. File-to-tape task may hang until cancelled. In this time veeam constantly writes logs of this task to archive. Size of archive is 2-4Gb.

Could you give more details, please?
Do you receive any message when the file to tape job is cancelled? Does it write files to the tape at all?
Thanks!

Also what are the source and destination settings for that File-to-tape job?

Thanks

I found couple of errors in mail like "Volume F: have 137708 problems. Details: File not found.Session has timed out". Task was executing for 2 days before this exception occured. In other cases I stopped task manually.
Source is file server with Server 2012 R2. Destination is tape library IBM TS3200 connected to this server.

"Volume F: have 137708 problems. Details: File not found.Session has timed out".

Any chances that some files on the source were modified/deleted while the job was running?

Yes it`s possible. I will make some changes in my backup schedule and see what will happen. Thank you.
