The major improvement of the version 4.2 is the possibility to create virtual servers on different TCP ports. This means that multiple virtual servers can share one library.
Every virtual server is independent.
A specific license is required to use this feature. You can specify the owner of a tape or a pool if you have configured virtual servers. The owner of a pool or a tape can display only his own pool or tapes. It is possible to enter an e-mail address for each Arkeia user. Arkeia can send an e-mail when the backup is finished or when a new tape is needed.
