I would like to create external/offsite backup for some server and desktop true the free Veeam Windows Agent software.
I will like to use the VBR as backup destination, for all the server / desktop.
(I know that the server/desktop will be unmanaged from VBR, and only mangement direct from the klient server or desktop.)
I cut use the VBR Community Edition, but that will "only" allow 10 server/desktop, Unfortunately, that's not enough.
So here are my questions

1.)
I've read somewhere if I buy a socket license for VBR eg "Veeam Backup Essentials".
Then a unlimited number of "Veeam Agent for windows Free" will be able to connect to the VBR, and use the VBR as an unmanaged backup destination.
Can someone confirm that ?
2.)
Since my clients (server/desktop) is external, I will need to open up my firewall for port TCP 10001, in order for my agent to connect/backup to the VBR server. And my client don´t have static IP, so I must open TCP 10001 Worldwide.
Is port TCP 10001 secure/safe enough for that ?
Is the traffic running on this port 10001 encrypted, as eg. TCP-443 HTTPS ?
3.)
Can the "File level backup" run with CBT ? or is that only the images backup that can do that ?
For faster "File level backup" on large files.
Thanks for you help.!
