Hi there,
I run Home Assistant for about a year as a VM on an ESXi host. It is set up to backup to a Nas share every day and keep 3 backups in retention. The backup share where this is stored has been exploding in size since this was set up, the last folder alone. called 'Latest is more than 300GB. I tried to understand the folder structure but gave up as each folder contain what seems to be full and partial backups.
Anyway, My Nas had a critical issue with two disk failed, so now I am trying to recover for the last 3 days.
Any attempt to deploy a new instance and upload from the WebUI to restore from backup has ended up in error 504 after a few minutes uploading what i think is the latest full, backup (6.5GB file)
Reading the forums, I see apparently there might be an issue with corrupting the backup if you try to upload backups taken to a Nas share as the web interface does not expect the backup to be compressed (?)
So I tried again, this time adding the samba share as ‘backup’, then as ‘media’ to my new HA instance, hoping it would then find the backups. I can add the share just fine, then the appliance still sees no backup whatsoever and offer to take a new backup.
Today after many different attempts, I have deployed again new instance, enable ssh and sftp, and I am decompressing the ‘full backup’ tar file I tried to upload earlier.
→ Can anybody confirm if I can just drag and drop the contents somewhere on the new HA instance to recover my backup?
Unfortunately I do not have access to the my old VM at all as the Datastore can’t be mounted.
Is there any best practices to backup (as in, is there a way to take backups you can actually restore?) I guess I will need to shut down the VM and export to OVA every week from now on as the backup in HA can’t be trusted. At least this will save a lot of space. I have about half a TB of HA backups just for this HA instance, and so far none of it is useful.
Sorry if this sound negative, but the HA backup thing is definitely completely broken.
