ansible_role_restic_archiver ====================== > **Beta:** This role is in beta status. ## Description [Restic](https://github.com/restic/restic) is a versatile Go based backup solution which supports multiple backends, deduplication and incremental backups. This role installs restic on a client, configures the backup repositories and optionally sets up cronjobs to run said backups. Aditionally, it will setup executable scripts to run a Backup manually. > This Project borrows heavily from the > [donat-b/ansible-restic](https://github.com/donat-b/ansible-restic) > ansible role. We try to make this role more semver deployment friendly > by allowing to use version tags and keep these snapshots and adapting the > automated backup definition for use with windows systems. ### Backup Scripts This role will create a backup script and a file with credentials usable with the `source` command on linux for each backup in the `restic_script_dir`. These executable scripts can be used to manually trigger a backup action, but are also used for automated backups if you have set `restic_create_cron` to true. make sure to not change the files manually, as this can interfere with your backups quite a bit. on Linux, if you want to take a manual snapshot, you can run the backup like this: ```bash $ /path/to/backup/script/backup-example.sh ``` by default, such a snapshot will be given the tag `manual`, so you can distinguish them from automatically created snapshots. You can also append more tags by simply appending them: ```bash $ /path/to/backup/script/backup-example.sh --tag deployment ``` ### CRON / Scheduled Tasks In order to make use of defined backups, they can be automatically setup as scheduled tasks. You have to be aware of the fact that (on linux systems at least) you need to have administrator permissions for configuring such an action. If you cannot use the automatic creation of the tasks, you can still make use of the generated scripts. If you are for example on a shared hosting server and can define a cronjob via a webinterface, simply add each backup file to be executed. Make sure to prefix the command with `CRON=true` to imply that the snapshot was created via a scheduled task: ```bash CRON=true /path/to/backup/script/backup-example.sh ``` ## Installation ```bash ansible-galaxy install arillso.restic ``` ## Requirements * bzip2 ## Role Variables | Name | Default | Description | | ---------------------- | -------------------- | --------------------------------------------------------------------------- | | `restic_url` | `undefined` | The URL to download restic from.

You can specify the following keys: ```yaml exclude: exclude_cache: true exclude: - /path/to/file iexclude: - /path/to/file exclude_file: - /path/to/file exclude_if_present: - /path/to/file ``` Please refer to the use of the specific keys to the [documentation](https://restic.readthedocs.io/en/latest/040_backup.html#excluding-files). ## Dependencies none ## Example Playbook ```yml - hosts: all roles: - restic ``` ## Author - Matthias Leutenegger
