Having made good experiences with BackupBox, we now provide BackupBox-Lab for lab PCs. Backups are triggered on the client (push vs. pull), are encrypted and usually very fast. It is meant for self-managed PCs within the ETH network. If you are planning to backup multiple machines (eg. all measurement machines in your group), please contact us, we will provide you with an impersonal, shareable login.
BackupBox-Lab is self service and has its own website. Please find all usage and installation instruction over there.
