How does the verify in BE 2010 R2 work?
A verify is where Backup Exec reads the data it's written for the backup, and ensures that it's consistent. It doesn't compare it with the original backup data or anything like that
Where is the verify executed, on the BE media server or on the server where the backup runs?
On the Backup Exec media server.
Who has more usage/load the agent or the media server?
The media server - the agent isn't doing anything during a verify.
Is there a lot of traffic/bandwidth used when the verify runs or does it run entirely on the Backup Exec media server?
No bandwidth is used during the verify, as there's no need to communicate with the Remote Agent.
How complex is the verify for the media server?
Not very.
Could a duplicate to tape job affect the verify (for instance a running verify of the file-server and a duplicate job of the already finished mail server at the same time)?
I would imagine it could. If you're trying to verify a backup job on a Backup-to-Disk device at the same time as writing another backup job to it, you may be getting poor disk perfomance.
What configuration do you have for the disk holding your Backup-to-Disk folder?
