UrBackup is an easy to set up Open Source client/server backup system, that through a combination of image and file backups accomplishes both data safety and a fast restoration time. File and image backups are made while the system is running without interrupting current processes. UrBackup also continuously watches folders you want to be backed up in order to quickly find differences from previous backups. Because of that, incremental file backups are really fast. Your files can be restored through the web interface, via the client or Windows Explorer while the backups of drive volumes can be restored with a bootable CD or USB-Stick (bare-metal restore). Currently, there are over 21,000 running UrBackup server instances (with auto-update enabled) with some instances having hundreds of active clients. A web interface makes setting up your own backup server really easy. The custom client makes fast file and image backups possible.

We believe you shouldn't have to give up your privacy or control to get the benefits of the cloud. Arq backs up your files to a cloud account you already have, or attached disk, or both, with strong, end-to-end encryption so your data are only readable by you. Arq uses filesystem snapshot technology to make perfect, point-in-time backups of your files, even if your files are changing during the backup process. Arq keeps multiple backups of your files — a backup history. So if you discover a file was corrupted, or accidentally deleted, or encrypted by a ransomware attack, you can go back and get the old version. Arq Backup integrates with many different cloud providers. So if you have a cloud account with some extra space available, use it for encrypted, versioned backups of your important files.
