Kopia is a free, open source cloud backup software with simultaneous compression and encryption.
Kopia supports backup of files and is suitable for both businesses and individuals. It supports many major cloud services that are usually reserved for storing backups.
It is a fast and safe tool backup that runs in the background, through a set schedule.
Kopia is available in both a command line interface (CLI) and a graphical interface (GUI). You can choose to create unlimited snapshots of a folder and recover any version you want, with a few clicks. For backup storage it supports Google Cloud, Amazon S3, Backblaze B2, WebDav and some others.
The program perhaps the most powerful in its class and at the same time free. It supports many compression algorithms. This will help you save storage space and make the backup process faster and more efficient.
In its settings it uses "Policies" with which it defines each backup task in a policy. There you can select or exclude certain files from the destination folder, enable compression, and have custom scheduling options.
