Hi Wes,

Interesting idea Constantin.
However, perhaps instead of or in addition to your idea, I'd like to have a
mechanism or script that would overwrite the older snapshots [u]only if[/u]
some more current snapshot were created. Ideally this mechanism would
prevent your idea of expired snapshots being removed in some case where the
creation of new snapshots somehow failed.
yeah, that could be another pair of snapshot properties: number of snapshots to
minimally/maximally keep.
Additionally, by only removing the snapshots after the creation of their
replacement is successful, this should prevent the possibility of data loss
if there were a major system problem during the creation of a new snapshot as
well.
Yes, snapshot replacement should always be split up into creating a successor,
see if it was successful, then delete the old one.
Best regards,
Constantin
