#tools + #backup

If you back up your files to Backblaze B2 using software that uploads files when they change, Backblaze B2 retains old versions of the file. This is helpful because the old versions can be used if the original file is accidentally deleted. On the other hand, keeping old versions forever can clutter things. For an application like this, you may want a Lifecycle Rule that keeps old versions in a backup/ folder for 30 days and then deletes them, as in the following example:

Keep only the last version of the file This rule keeps only the most current version of a file. The previous version of the file is "hidden" for one day and then deleted.

Rclone is a command-line program to manage files on cloud storage. It is a feature-rich alternative to cloud vendors' web storage interfaces. Over 70 cloud storage products support rclone including S3 object stores, business & consumer file storage services, as well as standard transfer protocols.

Rclone has powerful cloud equivalents to the unix commands rsync, cp, mv, mount, ls, ncdu, tree, rm, and cat. Rclone's familiar syntax includes shell pipeline support, and --dry-run protection. It is used at the command line, in scripts or via its API.
