RS819 – No Ability to run Virtualization

Written by James McDonald

September 19, 2023

So just found out that budget Synology Units can’t run Active Backup for Business if their CPU’s aren’t enabled for virtualization

The RS819 runs a Realtek RTD1296 quad-core 1.4GHz CPU and the Package Center doesn’t offer Virtual Machine Manager or Active Backup for Business.

So you can’t use this to protect a VMWare VSphere or ESXi instance

It looks like you need an Intel or AMD CPU that supports virtualization to be able to use ABfB.

So a RS422+ will do it.

Bummer Hal.


I’m not sure if it’s just the RS819 I have which is non-performant but the performance has been terrible. Can’t send Veeam Backups to an SMB share reliably without the backups failing with I/O errors.

Have tried to create an iSCSI LUN and use that as the backup target but same problem.

Currently doing a factory reset, and have removed the disks, wiped them clear with diskpart with the hope of it becoming more reliable/performant after.

Update: I ended up replacing it with an RS422+ which is now working reliably…. perhaps this particular RS819 is just a lemon.
