UrBackup can protect individual files and system images, so a replacement must be tested against both recovery scenarios you actually use.
Choose a spare machine and a small folder of non-sensitive files. Run a full backup, change and delete some files, then restore a previous version to a separate location. If image backups matter, boot the recovery environment on spare hardware or a virtual machine and verify that the system starts. Measure recovery time, storage consumption, and whether the backup remains usable after the server is restarted.
Check retention rules, client permissions, encryption, and off-site copies. A green backup dashboard is not evidence that recovery works. Write down the exact restore steps and repeat them with someone who did not configure the backup system.
