CEDA Archive partial storage issues final update

The CEDA team have now restored the vast majority of datasets affected by the error that caused data to be mistakenly deleted. All priority datasets have now been restored. A small number of datasets are still awaiting restoration due to needing additional storage space - we are working on this and anticipate these datasets to be fully restored in the next few weeks. We still foresee a few problems, so please tell us if you spot anything.

We have learnt several important lessons from this experience:

• Our back ups work! Although the process has taken a little longer than we first estimated, the action of restoring data from back ups has been successful.
• Some internal processes need to change. We need to tighten up the way we add/delete data from the archive to make sure all files are counted in and out properly.
• Risky bulk operations, like data migration, need more time and effort to lower the risks.

Thank you for your patience whilst we have worked to resolve this issue.
