setting up/converting windows 11-> ubuntu

[bruce]

hey karl/list.

Thanks for the remarks.  Much appreciated.

The 30k view is to backup everything every 2-3 days, using 2 1TB backup
drives to bounce/rotate between. This would give me a max of a 3-4 day gap
of lost information, assuming the backup drives dont fail.

So there would need to be an auto process for all of the backup processes
as well as periodic testing of backups.

All off this would be local. This would be for my personal use.

I think what I'm really in need of is a short term/initial sysadmin to
setup and test the process.

thanks
