Thank you for the script! This coupled with a Windows job to squirrel away the backup separately will do the trick nicely.
As a PS, my thanks to the whole community that has developed weewx. For years I've been stuck on Davis's creaky old Weatherlink software to archive the data and upload to Weather Underground. Having a dedicated little device to do it is so much better. - Jeff On Fri, Jun 21, 2024 at 3:30 PM vince <vinceska...@gmail.com> wrote: > My script for Linux is (here) > <https://raw.githubusercontent.com/vinceskahan/vds-weewx-backup-data/master/weewx-backup-copy.sh> > if > you want to see how I do it.
