Incus publish storage location

Incus

Hi All,

I want to backup a huge container. I make a snapshot from the container and then publish it. after that i will export the image to a file.

However my question is it possible to store the publish on a different drive? I have not enough storage and want to write it to a usb drive.

You can configure Incus to store its images and backups within a storage pool rather than directly on the host.

That’s done with the storage.images_volume and storage.backups_volume server config keys.

when i want to revert the storage to the deafult can i do this:

incus config set storage.backups_volume default /var/lib/incus/images ? Even if there is allredeay data in it?

No, you’d just unset the keys:

  • incus config unset storage.backups_volume
  • incus config unset storage.images_volume

If you perform:

incus export c1

You get a c1.tar.gz in your pwd.

Why is it that there are redundant copies of all exports in this location as well?

/var/lib/incus/backups/instances

Because incus export is making use of the backup API.

It effectively triggers a server-side backup which lands in /var/lib/incus/backups/instances, then gets downloaded by the client and deleted from the server.
