Reset latest snapshot to avoid it getting stale
...
When switching to new storage that doesn't yet have any snapshots, we would otherwise keep the old latest snapshot around.

Split up success and error notification
...
Now, we don't do partial backups anymore. A snapshot is only done at the end and no information can make it to the backup before. Hence the old error notification with number of apps backed up didn't make sense anymore.

Offer option to recycle backup after restoring
...
The most common restore scenario is assumed to be moving from one device to another, like when the old one was lost or stolen. Most users probably don't continue to use the old device themselves still.
Since they just restored this backup on their phone, most data is already in this backup. Deduplication allows re-using that, so it doesn't need to be saved again.

Delete repo and exit process when key changes
...
There is no easy way to re-initialize all data based on the old key, so to prevent usage of the old key we need to exit our process. When the app is started again, only the new key will be used.

Clean up metadata as it lost most of its importance
...
Historically, metadata was uploaded to the backend after each app update and contained all essential data that is now in snapshots. We still support reading metadata for legacy backups and use the metadata classes as a common wrapper for snapshots. However, there is no need anymore to write out complete historic metadata and maintain duplicated unused information there. This got removed. THe information we do still save and write out is only for UI representation of backup state.
The time of last backup is now managed by SettingsManager.

Fully implement BlobCache
...
This class is responsible for caching blobs during a backup run,
so we can know that a blob for the given chunk ID already exists
and does not need to be uploaded again.
It builds up its cache from snapshots available on the backend
and from the persistent cache that includes blobs that could not be added to a snapshot,
because the backup was aborted.
