BackupPC is highly configurable and easy to install and maintain. See http://backuppc.sourceforge.net/ Maintainer Stephane de Labrusse at stephdl@de-labrusse.fr Is this Module helpful to you ? Please consider donating Installation First you need to install my repository, see how to do it Then you have to install the copr BackupPC repository wget https://copr.fedorainfracloud.org/coprs/hobbes1069/BackupPC/repo/epel-7/hobbes1069-BackupPC-epel-7.repo -O /etc/yum.repos.d/BackupPC4.repo Then you can proceed to the nethserver-BackupPC installation. yum install nethserver-BackupPC4 --enablerepo=stephdl Upgrade from BackukPC v3 first you must remove the V3 rpm -e --nodeps nethserver-BackupPC BackupPC then install the copr repository wget https://copr.fedorainfracloud.org/coprs/hobbes1069/BackupPC/repo/epel-7/hobbes1069-BackupPC-epel-7.repo -O /etc/yum.repos.d/BackupPC4.repo then install the rpm yum install nethserver-BackupPC4 --enablerepo=stephdl You have to add manually all your hosts, the configuration should be found and valid, find the name by `ls /var/lib/BackupPC/pc` 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 in the user panel of the server-manager) 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 The user with the administrator privileges is the user 'admin', think to create it and set a password Then go to 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 Backup your clients on the network Backup a Linux host with rsync To configure a Linux host client to be backed up, configure SSH from the backup server as follows in order to exchange certificates and to perform a login without passwords. 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. Now you can go to the admin backuppc panel to set the backup of your host by the rsync protocol Note: There are times when the backuppc user needs a real shell specified in /etc/passwd, for example, when the backuppc user is used to run sudo commands or pre/post scripts. Of course you can use a lot of other protocols (smb,ftp,rync,rsynd,tar,…) Folders/files exclusion The UI is not very easy to understand how to exclude file or folder, this is a screenshot to explain it Backup a Windows Client with rsyncd To configure a Windows client to be backed up via the protocol rsyncd, install rsync on the Windows client. rysnc needs to be running as a service on the Windows client to ensure communication. You have a web folder to ease this installation, go to https://YourIP/cygwin and log in with the user 'admin' (create it and set a password in the server-manager) When you download and run cygwin-rsyncd, the cygwin and rsync files are installed in c:\rsyncd. A new windows service called RsyncServer is created and activated (ie: run). The c:\rsyncd directory will have an uninstall executable which will remove the service and installation files. You will need to edit the c:\rsyncd\rsyncd.conf and c:\rsyncd\rsyncd.secrets files to set your client-specific shares, backup user name and password. You should restart the Windows RsyncServer service to get the new settings or restart your computer. You can find the rsyncd.conf and the rsyncd.secrets files. They can be used as configuration files, but you can also write your own options in rsyncd.conf. The file rsyncd.secrets contains the master password, you can use it or change it to increase the security. Dont let in all hands this secret file. Once rsyncd.conf and rsyncd.secrets saved on your windows client and the settings adjusted to the correct values, you need to run a .bat file to adjust the windows firewall (the TCP port 873 need to be opened and the ping incoming request must be allowed). Please use the correct version backuppc-fw-W7.bat or backuppc-fw-xp.bat files. Past the content in a file, name it with a .bat and run it as an Administrator you can find (copy and paste the content or save the file) cygwin-rsyncd.exe rsyncd.conf (use it as is or like a template) rsyncd.secrets (your random password, change it if you want) backuppc-fw-W7.bat (a bat to open the 873 port in the W7 firewall) backuppc-fw-xp.bat (a bat to open the 873 port in the XP firewall) Example of rsyncd.conf We have share name (cdocs), path, the valid user , the path to the rysnc.secrets file, an allowable host (this being the local backup server IP), modes, read only and list. The options are mostly explained in the file. [cdocs] Path = /cygdrive/c/Users/<USERNAME> comment = c: User Data strict modes = false auth users = <valid-back-up-user> secrets file = c:/rsyncd/rsyncd.secrets hosts allow = 192.168.1.1 read only = false list = false This is strings to write in the configuration of your host in backuppc RsyncShareName <-> value of [cdocs] (eg cdocs and all other shares in rsynd in your window host) RsyncdUserName <-> value of auth users RsyncdPasswd <-> written in the secrets file XferMethod <-> rsynd The final thing that must happen to make rsync work properly is to load rysnc as a service on the Windows client. The file service.bat shows the following command to accomplish this: c:/rsyncd/rsync.exe -a "--config=c:/rsyncd/rsyncd.conf --daemon --no-detach" There is also a “gotcha” – sometimes port 873 is blocked by Windows Firewall, so you may need to fix that ( use the provided .bat following your microsoft OS) Clean up BackupPC Clean up the old backups sudo -u backuppc /usr/share/BackupPC/bin/BackupPC_nightly 0 255 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. E-smith database The settings of e-smith database are workable as is, they are here for documentation purpose # 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-BackupPC4-update Known Issues “aborted by signal=PIPE” Sometime the backup fails with this error, this error is related to the remote ssh service. You must set in the /etc/ssh/ssh_config of your remote host ServerAliveInterval 120 then restart your ssh service One other way could be to set in the setting of backupPC (RsyncClientCmd)the default value for all hosts $Conf{RsyncClientCmd} = '$sshPath -o ServerAliveInterval=120 -q -x -l root $host $rsyncPath $argList+'; Miscellaneous 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 less /var/log/httpd/error_log less /var/log/messages less /var/log/BackupPC/LOG In order to debug you can launch the event and look if something goes wrong in log after you launch it signal-event nethserver-BackupPC4-update Issues Please raise Issues on github Source sources are https://github.com/stephdl/nethserver-BackupPC4 module stephdl backuppc4.txt Last modified: 2021/03/29 14:07by Stephane de Labrusse
