This setting specifies the minimum retention period that the vault retains its recovery points. If this parameter
is not specified, no minimum retention period is enforced.

<p>
If specified, any backup or copy job to the vault must have a lifecycle policy with a retention period equal to
or longer than the minimum retention period. If a job retention period is shorter than that minimum retention
period, then the vault fails the backup or copy job, and you should either modify your lifecycle settings or use
a different vault.
