I just thought I would ask for opinions on backups that people use. I have
thought about the old fashioned dump/restore; IDK if that would be good for
modern use or not. My system isn't really that big. My allotted size is 30 Gig,
and it's not full. There's dar and xar and fsarchiver. There's backing up with
btrfs too.
I am thinking about back ups of the whole system and rpms I have
installed. And maybe not backing up logs, old settings like are stored in the
root directory of the user(s) and root account.
Does anyone use any of these or other backups? I just want to save my rpms
and not have to download all from scratch. IDK if dar or dump would backup
things like /sys or other system directories. I have created dump backups but
not really restored from scratch.

I've been using BackupPC for many years. It can use rsync via ssh for remote
backups or rsync directly for local (LAN) backup. It can automatically dedup
as well.
I use it to do daily incremental backups and weekly full backups for 12
systems, Four locally and eight remotely. A couple of years ago my workshop,
office and server room was destroyed in a fire. Because I had recent backups I
was able to get the four servers I lost back on-line and fully functional after
only a single day scrambling to get new hardware and rebuild the backup server.
Note that I send compressed archive copies to a remote server and that is what
I used to restore the primary backup server.
I have never had a problem with backups and have successfully restored complete servers and individual filesor directories for many years. My current primary backup server is running on CentOS 7 and has been since CentOS 7 was first available, and on CentOS 6 before that. My secondary backup server is on my local Fedora workstation.
I'll be building a new backup server, probably on Rocky Linux 9, soon. I
cannot imagine using anything but BackupPC.
As for you wanting to backup your system's RPM files, BackupPC can be
configured to backup an entire server or workstation, or only parts of them
including individual files. For example I backup only /etc, /home and a few
other critical directories on four servers, and for each of them I cause a
daily database dump and create a list of packages currently installed, that
also get backed up. It can take longer to restore those servers, but as they
are not critical infrastructure, I wouldn't matter much if they were down for a
day or two while we procure and rebuild those servers.
