I have a charitable client (40 users) who is running 4 VMs on a HP ML350 Gen9 Host (ESXi 6), 64GB of RAM, Dual Hex Core CPU, 8 * 900GB disks.
1 * MS 2012 Server - Domain Controller
1 * MS 2012 Server - Exchange 2013
1 * MS 2012 Server - FileMaker Server
1 * MS 2012 Server - Terminal Server
2* 8TB QNAP NAS - Shadow Protect backup to NAS, Image Manager running on a spare Hyper-V server to replicate backup to mobile drives to take offsite.
I'm after some recommendations/tips are tricks from an expert for this type of environment, ideally using the equipment they currently have, to have a solid backup/disaster recovery solution, to protect them from attacks, ransomware, corruptions, and hardware failures, bear in mind they are a charity, so the Microsoft products and services are pretty affordable.
I'm thinking if it makes more sense, I could rebuild the spare Hyper-V server (HP ML350 Gen6 with 32GB RAM and Dual CPU) to ESXi 6, and take advantage of the features of the VMware better, but open to options to use the spare HP ML350 Gen 6 hardware.
Office 365 with Exchange is on the cards, but we are also happy to keep going with on-premise until the right time to migrate.
Thanks in advance.
