+
+### Backblaze B2
+

+
+Still cheapest I believe. 10GB free.
+
+[Official Kopia documentation](https://kopia.io/docs/repositories/#backblaze-b2)
+
+* Register.
+* Create a new bucket for kopia repository.
+  * note **bucket name**
+* Add a new application key with the access enabled to the new bucket.<br>
+  After filling the info the site one time shows `applicationKey`
+  * note **keyID**
+  * note **applicationKey**
+* in Kopia add new repository `Backblaze b2` fill in the required information:
+  Bucket Name, KeyID and the Key.
+* Set global policy.
+  * Recommend setting compression, `zstd-fastest`.
+  * Set schedule.
+  * Retention rules.
+* Pick what to backup.
+* Done.
+
+In few minutes one can have reliable cloud backup that compresses the data
+and deduplicates.<br>
+
+**Save the repo password set plus all the info used.**
+
+Might be worth to check bucket settings, Lifecycle. I think it should be set to
+`Keep only the last version of the file`
+
+For cli just follow the official documentation.
+
+To restore files go in to Snapshots > Time > Start time > Mount as Local Filesystem.<br>
+The snapshot will be mounted as `Y:`
