Taking a Snapshot (BUI)
(i.e. an automatic snapshot schedule is set for them), then quotas should typically not include
snapshots in the calculation. Otherwise, the user may run out of space but be confused
when files cannot be deleted. Without an understanding of snapshots or means to manage
those snapshots, it is possible for such a situation to be unrecoverable without administrator
intervention. In this scenario, the snapshots represent an overhead cost that is factored into
operation of the system in order to provide backup capabilities. On the other hand, there
are environments where users are billed according to their physical space requirements, and
snapshots represent a choice by the user to provide some level of backup that meets their
requirements given the churn rate of their dataset. In these environments, it makes more sense
to enforce quotas based on total physical data, including snapshots. The users understand the
cost of snapshots, and can be provided a means to actively manage them (as through dedicated
roles on the appliance).
Managing User-Generated Snapshots
The "retain user-generated snapshots on the target" property allows you to manage user-
generated snapshots independently on the source and target appliances. With this option set, any
user-generated snapshots will remain on the target, even when the original snapshot is deleted
on the source. As long as this property is set, user-generated snapshots will not be destroyed
on the target. Any retained user-generated snapshots, that are no longer needed, will need to be
destroyed explicitly from the target appliance. For details, see Destroying a Snapshot
CLI.
