365 backup solution - Dell vs Veeam vs Microsoft

Backing up from Microsoft to Microsoft sorta violates one of the core tenets of backup - your fault domain is "Microsoft." Dell PowerProtect is Druva under the hood. After Dell or EMC (can't remember who it was) sold off Spanning and Mozy, Druva plugged the gap for endpoint / SMB / SaaS backup for Dell. Druva is... adequate. It's pricey for what you get, you'll be paying Dell as the middleman, and I'd rank it middle of the pack. Veeam is going to be better if you already have Veeam in place. I would not purchase Veeam just for 365 backup. That said, Veeam sells on ease of use, and it's not difficult to implement (it might cost, but professional services are generally not required or fairly straightforward). It's also not super-performant depending on where you're sending your backups, and large recoveries (essentially when you're recovering from a place with tiered pricing) are gonna be expensive. I would encourage you to reach out - if for nothing else other than to get quotes / see demos / understand what the rest of the market looks like - to Avepoint (which is by far the best player in this space and also have a suite of other very cool tools for compliance, but they only talk to bigger companies), Carbonite (which has both the remnants of CloudAlly as well as a white-label version of Avepoint that they shop to small businesses), Spanning, and Druva directly (I can't remember how Dell and Avepoint do deal reg, but if you're under 1000 users you're likely to get kicked back to Dell or Carbonite from Druva or Avepoint).
