Hint that a bunch of files are gonna be created related to a backup identified by name,
which is unique to the content of the backup, i.e. it won’t be the same name unless you are
backing up exactly the same thing.
Storage can choose to take actions like create a dedicated folder or do nothing.
Returns a string to identify this operation in potential succeeding file creation requests. Read more

Self: 'async_trait,
Asks to save a metadata entry. A metadata entry is one line of text.
The backup system doesn’t expect a metadata entry to exclusively map to a single file
handle, or the same file handle when accessed later, so there’s no need to return one. This
also means a local cache must download each metadata file from remote at least once, to
uncover potential storage glitch sooner.
Behavior on duplicated names is undefined, overwriting the content upon an existing name
is straightforward and acceptable.

The backup system always asks for all metadata files and cache and build index on top of the content of them. This means: Read more
