Then follow the below guide to install and configure the BackupPC and clients.

• First update the debian server by using “apt-get update” command.
• Then start the installation of backuppc with other dependency packages.
  • aptitude install backuppc rsync libfile-rsync-perl libfile-rsyncp-perl par2 bzip2
• This will go through the BackupPC installation process and it will prompt some configuration details. Make sure those things are written down in a paper.
• Then you have finished the installation you may access the backuppc via the web interface.

Configure the Backup time and schedule as required. You must need to specify the Share folder details, User, and Samba share user password in Xfer configuration. This can be done to individual PCs or for the whole system.

Window client Configuration

• Create a user called “backuppc”
• Share the folders with the share name “Backup”
• Then permit the backuppc user to access the share folders.

Above are common configuration for all windows distribution. But for the Windows 7 you need to edit the registry and add new value.

• Click “Start” Button –» All Programs –» Accessories
  
• Right mouse click on “Command Prompt” –» choose “Run as administrator” –» Continue
• Type “regedit” and press “Enter”, this opens the Registry editor with administrative privileges.
• Navigate to the following folder:“HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System”
  
• Add a new “DWORD (32-bit) Value” called “LocalAccountTokenFilterPolicy” (without the quotes).
• Change the value from “0” to “1”

Finally reboot the Client PC. That'll be all and you can make backup successfully.

mod_rewrite does not overwrite properly

If your server does not rewrite properly then check the SELINUX property. This is for CentOS server. 

If it's set to permissive or enable then apache mod_write does not work properly. 

You should set the selinux to disabled mod and reboot the server. Then it should work fine. 

Time not showing in Roundcube. ( Date column is blank)

When you installed Roundcube Mails are showing properly but the time of emails do not show.

This issue occurred due to php.ini file configuration.

You need to set correct time zone in the php.ini file.

vi /etc/php.ini

date.timezone = "UTC"

 then restart the apache service. That's all. Enjoy it.
