Hi Alan. Welcome to the Opto forums.
Your not going to be too thrilled in the answers, but this is the best thread on the subject:
Not much has changed.
I can bump it again and see what the software guys are thinking, as I say in that thread, it does not come up very often.
Personally (20 years using PAC Control in a hospital with about 30 controllers) I just did my own manually via some sub-directories and copy/pasting the archives.
The hospital had me prove that I could do a ‘disaster recovery’ of the automation system in 30 minutes, no Internet was allowed and running my own git repo was not something I was all that interested in at the time. (Also, not being a programmer with any training, skill or appreciation for automatic version control did not help).
