Since I started in 1982, I am somewhat old school I use tape drives. I currently have an HP LTO 3 and two VXA-320 backup drives on SCSI. I prefer tape drives because hard drives fail. In 2020, I replaced the VXA drives with a HP LTO4. In January 2021, I upgraded my workstation to Windows 10 and moved the Gigabyte setup into the backup workstation under VEEAM.
Gigabyte P67A-UD4-B3 motherboard Intel i7 2600K CPU 16GB RAM
Four Western Digital Black SATA drives: 1 TB, 2TB and a pair of 4TB
Intel GT NIC gigabit adapter Windows 7 Pro x64
I am able to get 90-100 MB/s backup speeds to disk across the network. I created 3 disk repositories Drive_M: Drive_N: Drive_O:
I backup every VM and split them on these repositories. I added the Windows 7 and 10 backups to VEEAM. VEEAM Community Version does 10 devices. I have my Windows workstations tape backup to the LTO 3 drive. The VMs are split up on two sets of tapes for the LTO 4. VEEAM Community is free. It does require a purchase of the VMWare Essentials Kit that is about $600 to start.
