Sun Microsystems 10 manual Dd Use case Multi-network backup

Version 3.1-enSolaris 10 Container Guide - 3.1 3. Use Cases Effective: 30/11/2009

3.5. Multi-network backup

Requirement

[dd]A company has several different networks that are separated in different stages either by firewalls or by routers. Different computers are installed in the individual networks. The backup is to be simplified by allowing direct system backups in the individual networks to be performed from one location without having to connect the networks by routing.

Solution

[dd]A server with backup server software is installed. Several zones are created on this server that have a network connection to each network. Backup clients are started in the zones that communicate with the backup server in the global zone via the internal network or that write directly on an available backup device as a backup server. The following details are used in particular:

∙Sparse root zones, that is, the zones inherit everything possible from the global zone.

∙The backup client or backup server software is installed separately for each zone.

∙A device is provided from the global zone to a local zone.

∙Network setup to connect from the global to the local zone.

Assessment

[dd] This use case has the following characteristics:

∙The operating division's expenses for creating the zones are low.

∙Backup and restore can be organized and carried out from one central location.

∙Higher backup speeds can be achieved by direct backup. Routers or firewalls are not burdened by backup data.

∙Possibly, licensing costs are saved for backup software.

∙Backup hardware is shared among departments and networks.

It has, unfortunately, turned out so far that some software manufacturers have not yet released backup server software for application in zones. Therefore, this use case is applicable with some restrictions only. Backup clients have already been released for application in zones here and there.
