Using Management Node Backup Tool

Management Node can be backed up using the hspc-mn-backup utility shipped with Parallels Business Automation - Standard distribution. After Parallels Business Automation - Standard installation hspc-mn-backup is located at the Management Node in the /usr/sbin directory.

The hspc-mn-backup utility allows you to:

Create Management Node backup.
Restore Management Node from backup.
Migrate Management Node from one server to another. In this case, hspc-mn-backup creates a Management Node backup, moves it to a server specified, and restores Management Node on a new place.

The following Management Node directories are backed up:

Directory	Description
`/var/lib/mysql/`	Parallels Business Automation - Standard database
`/etc/my.cnf`	MySQL configuration file
`/var/www/.ssh/`	Virtuozzo hardware nodes access
`/etc/hspc/`	Parallels Business Automation - Standard configuration files and license
`/etc/httpd/`	Frontend configuration files
`/etc/hspcd/`	Application server configuration files
`/var/opt/hspc-root`	Customization files
`/var/opt/hspc-event-manager/`	Event manager templates
`/vz/`	Parallels Virtuozzo Containers integration files

Management Node backup is a compressed tarball and by default, it is put into a current directory. A backup file is named hspc-mn-backup_YYYY.MM.DD (as design), where YYYY.MM.DD is a backup creation date in the Year.Month.Day format (for example, hspc-mn-backup_2006.09.06.tar.bz2). A backup creation date is also used as a backup identifier (ID) and you can use this ID in the hspc-mn-backup command line to specify a backup file to deal with.

Command line syntax:
