Re: [Veritas-bu] Netbackup change policy attribute question

There is no contradiction between your understanding and bpexpdate -recalculate.
The original question was about policy settings (not retention levels) and change in the policy will not be propagated. The change in retention levels will be propagated but will affect all backups of all policies which are using the affected retention level.

So if expiration date need to be changed for a subset of images covered by one policy the right way to do it is using the bpexpdate -recalculate command with -policy switch.

No, but it is my understanding that if you change the Retention Period for a Retention Level under Master Server Host Properties, that will change the period for all existing images, regardless of the policy, backed up under that level.

Hi,

No, NetBackup does not propagate changes in retention retrospectively.

If you need to change retention of existing images, you need to run bpexpdate with the -recalculate switch for the images in question.

Conversely, if I change the attributes from 45 days to 1 year, will the data that was backed up prior to the policy change abide to the new policy.
