Virtualization is increasingly gaining in importance every day and is now the first choice in many IT environments. It allows you to simultaneously run multiple operating systems on the same server.

By consolidating the server with the help of eEVOS, you can dramatically reduce operating costs in your company.
Secure and reliable backups are essential in order to fulfill the business requirements for disaster recovery scenarios. A fast and reliable recovery of VMs is also very important in order to keep the downtimes as small as possible.

Most important features

  • Easy setup and management
  • Backup Server can be any NAS Server
  • Maximum space savings thanks to deduplication
  • Support for Microsoft VSS (Volume Shadow Copy Service)
  • Easy backup job scheduling (hourly or on certain days)
  • Retention time (decide how long your backup should be kept on backup server) *
  • Independent from your eEVOS installation – restore your VMs on any eEVOS installation.
  • Automated Email reporting (daily, weekly, monthly) *
  • Email notifications in case of failed backups *

How does eEVOS VM-Backup work?

eEVOS VM-Backup analyzes the data blocks of a virtual machine and groups the duplicated blocks together.
This process is called deduplication.

The duplicate data blocks are backed up only once, so the backups and especially the subsequent backups are much smaller than using the conventional differential or incremental backups.

Any NAS server can be used as backup server. Due to the I/O load we recommend better performing NAS solutions such as euroNAS Premium .

How we make sure that the data is consistent

To achieve the greatest possible consistency, you can optionally perform an automatic checksum verify after each backup.
Support for Microsoft volume shadow copy service (VSS) ensures the highest possible consistency of your data on the Windows VMs.
As a result, all data within VM can be copied, that otherwise might be blocked by write operations (such as the registry or the system database).

VM-Backup Restore

The VMs can be recovered quickly and easily. The recovery can be performed on any eEVOS server.
There are different types of restore depending on your requirements

New VM

This option is offered automatically if there is no virtual machine with this name on the eEVOS Server.
During recovery, it will automatically create new VM on the drive of your choice.
This option should be used when recovering on a new system or migrating VMs.


When restoring to a snapshot, the restored VM will be shown in the snapshot management of the VM. You can then use the option “recover from snapshot” to set this VM online and replace existing running VM.
Another advantage is that it will restore the memory of your backup as well so you will get the same state of the running system as it was during the backup.

Replace existing VM

The existing VM is restored from the backup and completely replaced

New VM-Clone

Instead of replacing the existing VM you can create a new VM from the backup that will have a new name. In order to avoid conflicts, it will automatically change the MAC address of the virtual network cards.
