I have BackupPC-3.3.1-7.fc25.x86_64 installed on Fedora 25.  Stopped

Could never get the patches to 3.x to work for me.  My backup pool is
now more than a year out of date.

(I have been running an alternative backup mechanism (NetGear ReadyNAS
built-in backups), with a separate destination, so the old pool isn't
important.)

I'd like to install version 4.x, but must've missed any step-by-steps
that have been published. I've found the Hobbes repo, but there's
nothing there in the way of docs.

The main thing is to merge config.pl. Your old one should not be overwritten and the new one from the 4.x package should be renamed to config.pl.rpmnew.

You can diff the two and merge what you need from the old one into the new one. The main difference being (IIRC) that the rsync path and rsync arguments being split into two different variables.

Something like:

# cd /etc/BackupPC

# mv config.pl config.pl.old

# mv config.pl.rpmnew config.pl

# diff -Nau config.pl.old config.pl > changes.diff

Then review changes.diff and merge what you need over to the new config.pl

It is a bit time consuming because the supplied default config.pl and the changes made the first time you click save from the CGI interface create a lot of false positives in the diff. 

Thanks,
