You are quite right.
The info about directories to backup is in the file
/etc/BackupPC/pc/helen.pl .
I had been looking for a file called config.

Yes, it was pointed out to me that there are instructions in

in Step-7:-Talking-to-BackupPC.
I note that these instructions end by advising the user not to follow them,
but to set up the GUI method.

Incidentally, I've been running BackupPC on my CentOS-7 server
for about a week now, and I notice that no config file is created
in /var/lib/BackupPC/pc/helen, where helen is the host-name.
It seems the GUI method stores the config file somewhere else.

Sure there is.  All of the configuration is stored in text config
files.  There is a main config file for global options and each host has
a config file in it's own directory.

The GUI config editor is just an alternative to hand editing.  It uses 
the exact same files.


Keep in mind that the config files are stored separately from the 
backups.  On my system, the backups are under /data/BackupPC and the 
config files are under /etc/BackupPC.

Sure there is.  All of the configuration is stored in text config 
files.  There is a main config file for global options and each host has 
a config file in it's own directory.


Running BackupPC is simply a matter of starting the process.  There are 
various scripts available for manually starting backups and getting stats.


That said, the GUI is by far the easiest way to add new clients and look 
for failing backups or other issues.

I have a couple of questions that this raises.

1. Why exactly does backuppc want to ssh to root?

2. The graphical interface seems to be treated as an extra,

Another small query.
I see that BackupPC starts 6 copies of httpd running,

Can this number (6) be changed?

1. It's just the default, it can easily be configured to start rsync 
through sudo, you need root privileges to backup all files.


2. You can do all operations through CLI, all of it is mentioned in the 
documentation. 
http://backuppc.sourceforge.net/faq/BackupPC.html#Step-7:-Talking-to-BackupPC


3. As mentioned earlier, this is just the default apache config. And can 
be altered through httpd.conf (though I wouldn't mess too much with it, 
the defaults are normally fine).

Thank you for your response.
However, I don't believe this short section gives sufficient information
to configure and run BackupPC.
Basically, it just gives a way of finding out what is happening
while BackupPC is running.
(Also it finishes by advising you to use the GUI instead.)

For example, what command would you give to tell BackupPC
that you want to back up /var/www (to choose a directory at random)?

I don't think that is true.
The simplest way to configure BackupPC is to run it with user backuppc, 
by changing "User apache" to "User backuppc" in /etc/httpd/conf/httpd.conf .

That goes in the config file (typically the per-PC one for this kind of 
setting, since you won't back up the same dirs on all clients).

http://backuppc.sourceforge.net/faq/BackupPC.html#Configuration-File

The options are described in the following sections, that particular 
setting is described in the well named section:

http://backuppc.sourceforge.net/faq/BackupPC.html#What-to-backup-and-when-to-do-it

Really, the backuppc docs are pretty good.

[CentOS] BackupPC is not easy to setup

[Timothy Murphy]

I finally got BackupPC working under Centos-7.1
after several hours of pain.
I had been running it for several years under CentOS-6,
and probably CentOS-5, but there seem to me
to have been several new issues that arise with CentOS-7.

In my experience, the official documentation on this,
,
is more or less useless unless you have a very long time to spend.
It suffers from the usual Linux disease of having
inordinately long explanations of everything
with no examples of the actual commands a real person has to give.

The explanation in 
(which I only found later) is much better, 
though it starts with the warning
"This page is no longer maintained, having been abandoned on 2009-09-17".

I thought I'd write a 1-page note to myself of the steps I took,
in preparation for CentOS-8...
I have a couple of questions that this raises.

1. Why exactly does backuppc want to ssh to root?
Is this just a way of running BackupPC as root?

2. The graphical interface seems to be treated as an extra,
but what other way is there of accessing BackupPC?
Is there a CLI approach?
If so, where is the list of transfer requests kept?

Another small query.
I see that BackupPC starts 6 copies of httpd running,
but so far only 2 have ever been used.
Can this number (6) be changed?

Yes, in the configuration of you httpd.

To enable access to all of the files on the client.

It is also possible to run the backup running the rsyncd- daemon on the
client.

> Is this just a way of running BackupPC as root?

Why do you want this? It's not required to run backuppc as user root.

There are some CLI applications available, BackupPC_tarCreate for
example to restore file from the command line.

I don't want (or not want) to do this.
I was asking the reason for ssh-ing from backuppc to root.
I don't recall any other application taking this route ?

I take it then that there is no CLI method 
of setting up and running BackupPC ?

Incidentally, I don't recall ever changing the user and group
under which BackupPC is to run when setting up BackupPC under CentOS-6.
Maybe this was done automatically during the CentOS installation
of this program?
(I certainly never used suexec explicitly.)

its using ssh to run rsync on the backup target...   it uses root so 
that rsync can access all files.
