Osoris asked 2 years ago

I have Exchange Server 2016 3 virtual server with almost 300 mailbox
For this year I want to implement one of these solutions: backup or Archive .
My questions are :
1- which one important more to start with?
2- if I will go with backup then which one is best from your opinion: veeam or barracuda backup appliance? And why ?

3- if I will go with Archive then which better: to go with built in Archive solution in exchange or barracuda email archiving appliance ? And why ?

Thanks a lot
