How can I install the vhdz image I downloaded from urbackup on win sever2019 hyper-v? can you help me?
A .vhdz image is a compressed form of a virtual hard disk. You’ll likely need to decompress it first before being able to use it in Hyper-V. The administration manual has instructions on how to do so here in section 10.7: UrBackup - Server administration manual
Give that a try and see if you have more success
