Retention

You can inject the retention policy using a strategy.

Key	Parameters	Control
Configuration.Node.Retention	[at < path >] after < value > (days | weeks) keep ((every < value > (hours|days|weeks))|none)

Possible values :

• [at < path >] : optional parameter. If specified indicates the path from which to inject retention. In it is not specified, retention will be injected on the whole account.
• value : numeric value used to specify the beginning of the period (for the first value) and the frequency of the retention (for the second value).
• time units :
  • hours, days, weeks : pretty straight forward, isn't it ?
  • none : no retention's end

Important note

Thanks to go to the Data retention section for more thorough explanation of the data retention model.

Example

You wish to apply a linear 60 days retention on your backup account and a degressive 12 weeks retention on your D: drive according to the following model:

• After 1 week, keep one version per week
• After 4 weeks, keep one version per 4 week period
• After 12 weeks, do not keep any history

Resulting strategy :

Configuration.Node.Rotation : after 60 days keep none
Configuration.Node.Rotation : at D: after 1 week keep every 1 week
Configuration.Node.Rotation : at D: after 4 weeks keep every 4 weeks
Configuration.Node.Rotation : at D: after 12 weeks keep none
