Hello Taylor,
Thanks for your help.
In fact, i can't manage, i think this kind of behaviour, with system manager.
XDP is based on the label and to the destination the retention is applied on the snap's label. I can't have on the source volume more than 2 daily snapshots because of huge daily change in each volume.
For example, i need to have the daily snapshot of the sunday tagged "weekly" on the destination volume but still daily on the source.
I'm sorry if it is not clear at all.
I really don't want to use a script, it will be a nightmare to maintain that.
Thanks again
Serge
