The user must have a policy that grants it privileges to upload to the S3 bucket. This value is required when backend='s3'. * aws\_secret\_access\_key | string Secret access key for the AWS IMA user. The user must have a policy that grants it privileges to upload to the S3 bucket. This value is required when backend='s3'. * backend | string Accepted values are s3 | scp | sftp | ftp | rsync | file An empty string will disable backups. * backup\_frequency | string Default: manual Sets the crontab backup frequency to a valid cron string or one of the following: hourly|daily|weekly|monthly|manual If set to manual, crontab backup will not run. * deletion\_frequency | string Default: daily Using retention period, a crontab executes at this frequency to delete stale backups. Sets the periodic deletion cron's frequency to one of the following: hourly|daily| Note: hourly runs at 40th min mark every hour and daily runs at 2300 everyday. * disable\_encryption | boolean By default, duplicity uses symmetric encryption on backup, requiring a simple password. Duplicity also supports asymmetric encryption, via GPG keys. Setting this value to True disables encryption across the entire application. * encryption\_passphrase | string Set a passphrase required to perform symmetric encryption. * extra\_packages | string Space separated list of extra deb packages to install. * gpg\_public\_key | string Sets the GPG Public Key used for asymmetrical encryption. When set, this becomes the primary method for encryption. * install\_keys | string List of signing keys for install\_sources package sources, per charmhelpers standard format (a yaml list of strings encoded as a string). The keys should be the full ASCII armoured GPG public keys. While GPG key ids are also supported and looked up on a keyserver, operators should be aware that this mechanism is insecure. null can be used if a standard package signing key is used that will already be installed on the machine, and for PPA sources where the package signing key is securely retrieved from Launchpad. * install\_sources | string List of extra apt sources, per charm-helpers standard format (a yaml list of strings encoded as a string). Each source may be either a line that can be added directly to sources.list(5), or in the form ppa:/ for adding Personal Package Archives, or a distribution component to enable. * known\_host\_key | string Host key for remote backup host when using scp, rsync, and sftp backends. Valid host key required when using these backends. The format is: hostname[,ip] algo public\_key ex: example.com,10.0.0.0 ssh-rsa AAABBBCCC... * nagios\_context | string Default: juju Used by the nrpe subordinate charms. A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: juju-myservice-0 If you're running multiple environments with the same services in them this allows you to differentiate between them. * nagios\_servicegroups | string A comma-separated list of nagios servicegroups. If left empty, the nagios\_context will be used as the servicegroup * package\_status | string Default: install The status of service-affecting packages will be set to this value in the dpkg database. Valid values are "install" and "hold". * private\_ssh\_key | string base64 encoded private SSH key for SSH authentication from duplicity application unit and the remote backup host. * remote\_backup\_url | string URL to the remote server and its local path to be used as the backup destination. Backends and their URL formats: file: 'file:///some\_dir' ftp & sftp: 'remote.host[:port]/some\_dir' rsync: 'other.host[:port]::/module/some\_dir' 'other.host[:port]/relative\_path' 'other.host[:port]//absolute\_path' s3: 's3:other.host[:port]/bucket\_name[/prefix]' 's3+http://bucket\_name[/prefix]' scp: 'other.host[:port]/some\_dir' sftp: 'other.host[:port]/some\_dir' * remote\_password | string This value sets the remote server's password to be used for scp, ftp or sftp backups. If unset, it may still be able to authenticate via SSH private key. * remote\_user | string This value sets the remote host username for scp, ftp or sftp backups. * retention\_period | string Default: manual Sets the retention period of backups. By default, it is set to 30 days. Can be set to: manual, d, h but not both hours and days. For example, 30d, 7d, 36h, etc... If set to manual, crontab for deletion of stale backups will not run.
