Hi Xavi,

You can install MSP360 Backup agent on any machine and use trial license. Follow the article below to create bootable iso. As your server has RAID controller, do not forget to download them from the vendor website, unzip and specify the path to them in the "Path to drivers" field. USB or ISO file is created, boot it on the affected machine.
