You can try running the utility from this location -- it may already be there:
/usr/local/psa/bin/pleskbackup (
http://kb.swsoft.com/en/286)
Or you can simply install the utility with autoinstaller:
Just run '/usr/local/psa/bin/autoinstaller' (or '/usr/local/psa/admin/bin/autoinstaller')
OR:
1 Download the autoinstaller for your operating system from
http://www.swsoft.com/en/download/plesk8/ and save it on your server's hard drive.
2. Change your working directory to the directory where the Auto-installer utility resides, for instance: # cd /root/plesk
3. Set the execution permission for Auto-installer: # chmod +x plesk_auto_installer_file_name
4 Run the Auto-installer: # ./plesk_auto_installer_file_name
During installation, BU utility will be placed to the directory /plesk_installation_directory/bin (in order to work with the utilities, you should log in to the server shell as 'root').
During the configuration update, choose your current Plesk version and select 'Plesk Backup Manager' (you could also consider adding 'Plesk Updater' and 'Plesk migration manager' for future).
As soon as BU is installed, proceed with backing up your data:
ftp://download1.swsoft.com/Plesk/Plesk8.2/Doc/plesk-8.2-unix-backup-restore-guide/index.htm
With this utility you can back up individual user accounts with domains, individual domains (Web sites), schedule backups, restore your data from backup archives. If you grant your customers with the permission to use the backup utility, they can back up and restore their own account settings and Web sites through the control panel (there will be a shortcut to their backup repositories on their Home pages (Home > Backup)).
Backuping the entire server is only possible via the command line:
/plesk_installation_directory/bin/pleskbackup all <backup file name>
or:
/plesk_installation_directory/bin/pleskbackup all ftp://[<login>[:<password>]@]<server>/<filepath>
for help see:
/usr/local/psa/bin/pleskbackup --help
The created backup archive will include your control panel license key, mail server and DNS server settings, information on database servers, domain templates, virtual host skeletons, user accounts, domains, web sites with web content, SSL certificates, databases, mailboxes, site applications, and custom buttons.
