Backup Exec 2010 has just dropped, and I'm about to implement a new BEWS infrastructure, complete with CALs and new central servers.

When I specced this up last year, I ignored 2010 and focused on Backup Exec 12.5, since it's a mature product. In previous experience, major released of BE had numerous technical issues and seemed to improve significantly at the first service pack.

However, our refresh cycle on the backup infrastructure is slow, the main driver usually being lack of support for some new server type (in this case, ESX has driven our current upgrade need). With this in mind, I'm wondering if Backup Exec 2010 should be my first choice, as it'll last longer under current support than 12.5, which will approach EOL soon.

Has anyone got any perspective they could add to this? Right now, I'm leaning towards biting the bullet and going with 2010.
