ansible_role_restic_archiver

ansible role to "archive" restic backups.

The scenario for this role is:

• You have the restic rest server running in write-only mode
• you send backups from other servers to your restic backup server

Now you don't want to store all backups indefinitely, but only for the last days a daily backup and otherwise weekly, monthly, yearly a few... just like you do it.

Of course you don't want to give access to others, so you solve the whole thing with a local cronjob. And this cronjob is built with this Ansible role.

As a bonus feature, you can optionally transfer the backups to another disk (even with a different password). Which is also a very charming backup concept from a security point of view.
