Error "<packindex/pppppppp> says <snapshot/ssssssss> depends on missing pack <data/dddddddd>, non-restorable!"

The message is similar to the 'Reindex needed' issue. It indicates that a specific backup snapshot, 'ssssssss', refers to data chunks, 'dddddddd', that cannot currently be found inside the Storage Vault. The specified backup snapshot is not currently restorable.

The error message may show more than one snapshot.

The index of encrypted data chunks in the Storage Vaults is carefully curated. It is still possible for the index of data chunks can become mismatched with the actual chunks stored. This can happen:

if a file was manually deleted from the Storage Vault, or
if your storage platform experienced data loss for any reason (e.g. RAID failure), or
if the Unlock action was used in an unsafe way, or
if a retention pass went back in time (e.g. via VM snapshot resumption)

Solution

We need to remove the packindex 'pppppppp' from the Storage Vault, then run a Retention Pass into the Vault to recalculate and regenerate the packindex.
