==== BackupPC ====

BackupPC is a high-performance, enterprise-grade system for backing up Linux, WinXX and MacOSX PCs and laptops to a server's disk. BackupPC is highly configurable and easy to install and maintain. See http://backuppc.sourceforge.net/

I'm not the first author, it is an adaptation to nethserver of a smeserver contribs of Daniel Berteaud.

first you have to install my repository, [[nethserver|see how to do it]]

Then you can proceed to the nethserver-BackupPC installation.
  yum install nethserver-BackupPC --enablerepo=stephdl

==== Documentation====
Documentations are here : http://backuppc.sourceforge.net/faq/BackupPC.html
==== Usage ====

Once installed, the admin cgi user is 'admin' (think to set a password for ns6.6) but any users can perform a login however they can manage only the their backups(eg the admin user needs to set backups for this user). If you want to restrict the cgi interface only for the admin, then set the db 'CgiMultiUser' to disabled

see db commands

    # config show backuppc
    backuppc=service
        CgiMultiUser=enabled
        examples=enabled
        status=enabled
        sudo=/usr/bin/rsync,/bin/gtar,/bin/tar

  * CgiMultiUser -> enabled all users in ldap can use the backuppc CGI, disabled and only admin can do it
  * sudo-> you can add here more commands available by sudo to backuppc
if you want to modify something, then

    config setprop backuppc CgiMultiUser disabled
    signal-event nethserver-BackupPC-update

other DB available

    # config show httpd-bkpc 
    httpd-bkpc=service
        TCPPort=950
        access=none
        status=enabled

the service which run the other apache session can be controlled by 

  service  httpd-bkpc restart 

Available are  stop, start, restart, status or with the ns way (enabled or disabled)

    config setprop httpd-bkpc status disabled 
    signal-event nethserver-BackupPC-update

Then go to https://yourIP/BackupPC or Dashboard->Applications->BackupPC

You will find two urls
https://yourIP/BackupPC -> the cgi interface
https://yourIP/cygwin -> a web page to help the cygwin-rsyncd settings for windows

==== RSA Key ====

Automatically, a rsa key is created in /var/lib/BackupPC/.ssh (4098 bits) you can use it to authenticate without password if you want to backup a linux host

first you need to export the public key

    su -s /bin/sh backuppc
    ssh-copy-id -i ~backuppc/.ssh/id_rsa.pub root@192.168.xxx.xxx

and test if all is ok

     ssh root@192.168.xxx.xxx
if it is ok you can log without password, then do 'exit' to go out of the shell

**Of course you can use a lot of protocol (smb,ftp,rync,rsynd,tar,...)**

==== Remove all backups of a client ====

then

    rm -rf /var/lib/BackupPC/pc/client/
    sudo -u backuppc /usr/share/BackupPC/bin/BackupPC_serverMesg BackupPC_nightly run

==== Remove One backup of a client ====


    cd /var/lib/BackupPC/pc/client/
    ls
    rm -fR backup_number
    sudo -u backuppc /usr/share/BackupPC/bin/BackupPC_serverMesg BackupPC_nightly run


Removing a single backup must be done with extreme care. You can safely remove the last backup for example, but if you remove a backup on which another one is based on, you can screw up your backups

==== remove statistic line ====

After this, you will see space reclaimed and you can check it with df, but you still need to remove statistic line, otherwise you will see it in your web interface. To do that:

     vi /var/lib/BackupPC/pc/client/backups

  you can remove the line with the backup_number.

Relog to your web interface and voila! No more backup_number.

==== what it can be enhanced ====

some scripts to wake on lan computer before to backup them
some scripts to backup windows computers with  shadows copy

well a lot of more of course, i'm waiting your scripts and your ideas.
==== Debug ====
There is some logs if you need to debug

    ll /var/log/httpd-bkpc/
    total 8
    -rw-r--r--. 1 root root 694 May  4 06:03 bkpc_access_log
    -rw-r--r--. 1 root root 749 May  4 06:03 bkpc_error_log
    -rw-r--r--. 1 root root   0 Apr 19 05:09 httpd-bkpc-service_log

you can have a look also

    less /var/log/httpd/error_log
    less /var/log/messages

In order to debug you can launch the event and look if something goes wrong in log after you launch it

    signal-event nethserver-BackupPC-update
