Just pondering upgrade scenarios from 9.x to 10.
Is it possible to perform a selective backup on a running 9.2 system that includes all of the configuration and folders but doesn't include the content of the folders. Intent is it allow a rapid test of a restore to a 10.x server without having to wait for a couple of TB of file data to be saved then restored, just the config.
Even with an existing tested backup system in place there is a degree of doubt that Murphy and his legal team will arrive at some stage during an upgrade. Even more so if partial hardware updates are performed during the process making a fall back difficult. Utopia would be another system to migrate to but circumstances make this only partially possible.
I have access to a proxmox setup but it has less storage capacity than my current 9.2 system so a full restore during a test isn't currently possible.
