Just wanted to say I think Hassio is pretty bulletproof.
I was running it for years on a PI but my SD cards would fail eventually. I discovered that by adding ram to my Synology DS220+ I could run it in a VM.
Well My NAS got hit by lighting and would not light up. I have the autobackup HACS addon and a scheduled task to copy the backups from.the samba share to my win8.1 desktop
So I loaded oracale virtual box on my desktop, downloaded the vmk file and followed the instructions for configuring the VM. After a while I was presented with a new install setup or option to restore a backup. Lo and behold after a while I was alive again.
Then I decided I did not want the VM on my main desktop so I repeated the above after a fresh backup to my PVR camera system with 16gb ram. Both windows systems seem to be faster than the Synology nas.
Then my replacement NAS arrived and after following the procedure to take my discs out of thee bad nas into the new nas I had my original Hassio up and running. Copied the latest backup from my windows box to the back share on hassio and then it was listed in the native backup section of hassio. Restored again the backup I made before shutting down the windows VM and all is well.
So the 2 takeaways are
#1 Automate backups to a media that will be available if Hassio is down like a windows folder or even a thumb drive.
#2 Hassio backups are hardware independent. I went from a different kind of VM (ova I think) to vmk, and back.
Thanks for a great product !
