Spec score 9.3 #5 of 151 in Backup software

What it is

UrBackup is backup software from UrBackup in Ulm, Germany, covering computers, mobile devices and servers. It runs on Android, Linux, macOS and Windows. The listed backup scope combines file and image backups, while restore modes are mixed. Ransomware protection is included. UrBackup core is AGPLv3+ open-source software with a self-hosted server for file and image backups; no price is listed for that plan. A free plan is available, with paid options from €15.50. The Change block tracking option for the UrBackup Client on Windows costs €15.50 a month, billed per client excluding VAT. It speeds incremental image and file backups, includes 2.x updates and works with UrBackup Server 2.x. A separate client for Microsoft Hyper-V 2016 or later backs up virtual-machine disks as images and restores those images to VHD or VHDX files.
