What this does do: - appends to manifest and syncs before deleting old files from disk, to ensure safety amidst kill -9 or system crash What this could do but does not: - include file size, smallest/biggest keys in the manifest - keep track of value log files It might be nice to have file size and include all files, to verify that a `cp -R` or file-based backup/restore has included everything. Right now this just gets us crash safety.
