debops.rsnapshot default variables

Host groups

rsnapshot_clients

Required. Inventory group of hosts that have rsnapshot installed and keep the backup files.

rsnapshot_clients: '{{ groups.debops_service_rsnapshot|d([]) +
                       groups.debops_service_rsnapshot_clients|d([]) +
                       groups.debops_rsnapshot|d([]) }}'

rsnapshot_servers

Required. Inventory group of hosts that should be backed up by rsnapshot. They have rsync installed and clients connect to them.

rsnapshot_servers: '{{ groups.debops_service_rsnapshot_rsync|d([]) +
                       groups.debops_service_rsnapshot_servers|d([]) +
                       groups.debops_rsnapshot_rsync|d([]) }}'

rsnapshot_external_servers

List of dicts which define external servers to backup on a particular rsnapshot client host. Most of the keys have the same names as the main debops.rsnapshot variables but without the rsnapshot_ prefix. The name key is required. See How to backup hosts outside of Ansible cluster for more information.

rsnapshot_external_servers: []

Examples:

- name: 'host.example.org'
  sleep: '10'

Backup client configuration

rsnapshot_snapshot_root

Directory where backups are stored.

rsnapshot_cmd_rsync

Main script executed by rsnapshot script to perform backups.

rsnapshot_scheduler_type

Method by which rsnapshot-scheduler issues new backup jobs:

• batch: use batch from the at package to run backups depending on system load. If not present, it falls back to sleep.
• sleep: use sleep command with a random delay in minutes to spread the load of the backup jobs.

rsnapshot_scheduler_type: 'batch'

rsnapshot_scheduler_batch_queue

Queue used by the rsnapshot backup jobs. A queue should be defined by a single, capital letter to ensure that the jobs are managed by batch command according to the current load average.

rsnapshot_scheduler_batch_queue: 'R'

rsnapshot_scheduler_batch_command

Command used to schedule backup jobs.

rsnapshot_scheduler_batch_command: 'at -q {{ rsnapshot_scheduler_batch_queue }} now'

rsnapshot_scheduler_sleep_max_delay

Maximum delay in minutes for the sleep scheduler type.

rsnapshot_scheduler_sleep_max_delay: '20'

rsnapshot_scheduler_run_max_delay

Maximum delay in minutes for the scheduler to check if another backup job has finished before running.

rsnapshot_scheduler_run_max_delay: '5'

Backup server configuration

Server configuration should be defined in the respective host file in the inventory, either in host_vars/ for a single host, or in group_vars/ for entire groups of hosts.

rsnapshot_retain

List of snapshots managed by rsnapshot for a given host. Each element is a YAML dictionary with following keys:

• name: name of the snapshot
• number: number of snapshots to preserve

rsnapshot_retain: '{{ rsnapshot_retain_hourly }}'

rsnapshot_retain_hourly

Keep a set of hourly snapshots which are then rotated daily, weekly and monthly.

rsnapshot_retain_hourly:

  - name: 'hourly'
    number: 6

  - name: 'daily'
    number: 7

  - name: 'weekly'
    number: 4

  - name: 'monthly'
    number: 6

rsnapshot_retain_daily

Keep a set of daily snapshots which are then rotated weekly and monthly.

rsnapshot_retain_daily:

  - name: 'daily'
    number: 7

  - name: 'weekly'
    number: 4

  - name: 'monthly'
    number: 6

rsnapshot_one_fs

Allow or prevent rsync` from crossing filesystem boundaries.

rsnapshot_one_fs: '0'

rsnapshot_ssh_port

This variable is not used directly by the rsnapshot command, but can be used by Ansible and scripts to connect to the correct port if SSH has been configured differently.

rsnapshot_ssh_port: '22'

rsnapshot_ssh_args

Additional arguments for the ssh` command.

rsnapshot_ssh_args: '-p 22'

rsnapshot_rrsync_script

rrsync script will be installed in this path (by default, /usr/local/lib).

rsnapshot_rrsync_script: '{{ (ansible_local.root.lib
                              if (ansible_local|d() and ansible_local.root|d() and
                                  ansible_local.root.lib|d())
                              else "/usr/local/lib") + "/rrsync" }}'

rsnapshot_ssh_command

Command which will be added to the SSH key in /root/.ssh/authorized_keys of each rsnapshot server host. By default it allows for read-only access to the entire filesystem.

rsnapshot_ssh_command: 'ionice -c 3 nice {{ rsnapshot_rrsync_script }} -ro /'

rsnapshot_backup_user

Override server backup user (by default, root).

rsnapshot_backup_user: False

rsnapshot_backup_host

Override server backup host (by default, FQDN of the host).

rsnapshot_backup_host: False

rsnapshot_backup_path

Override server backup path (by default, /, root filesystem directory).

rsnapshot_backup_path: False

rsnapshot_uuid

Add the host's internal UUID to the backup path, creating an unique backup for each instance of the server host, if the hostnames are reused.

rsnapshot_uuid: True
