Backup4all is Windows backup software that protects personal and business files and can back up to several destinations, including Google Drive, Microsoft OneDrive, Dropbox, Amazon S3, Microsoft Azure, Box and HiDrive. It runs on Windows 11 back to Windows Server 2008 and is installed on the user's own computers rather than run as a vendor-hosted service.
The software is developed by S.C. Softland S.R.L., a Romanian company based in Cluj-Napoca and founded in 1999, so the vendor is established in the EU. The software is not open source. Because it runs on the customer's own systems, the backups are stored wherever the customer sends them. A US cloud destination brings US law into play for that copy. A European organisation can keep the whole chain within the EU by choosing European or self-operated storage.
