Yes, since everyone on the official evaluation period is allowed for getting support (based on staff availability, though).

Does Windows Server 2012 R2 delete snapshots after 72 hours?

I believe this is a Veeam limitation. You can ask Support about a registry value, though you might instead want to focus the support case on improving performance to fit the backup within that window.

Thanks Alan, I doubt that the we will be able to fit the backup into 72 hours, as bottleneck is the network with 1GBit. This is the reason why I would like to go synthetic full once the initial backup ran successful. Support does not seem to answer me (for the time being), so If you or someone else is aware of this reg setting, I would really appreciate to have this info: We have to decide this week whether or not choose VEEAM or stick to BackupExec..

The key is mentioned in the v7 Patch 3 notes:

• Maximum volume snapshot life time is now customizable using the hvSnapshotLifeTimeHour (DWORD) registry value. Default value is 72 hours, but customization may be necessary to allow full backup of very large VMs on slow backup hardware.

Hi, just to follow up - setting the reg key worked. Backup finished after 140 hours!

edit says: I am now wondering whether I can set the deduplication ratio to a better rate now that we are running synthetic fulls only..

Considering the size of your backup file, I would recommend to go with the "Local 16+ TB" setting, performance-wise.
