That is standard procedure, unless you have fancy expensive tools.

Sure, but to create such a thing, you need a considerably more 
sophisticated process for creating incremental backups. The 'standard 
procedure' backs up all data created or modified since the last full 
backup. You only need the metadata of all the current data to do that, and 
that's all in the file system.

You want deletion records for all data deleted since the last backup. You 
need both old and new metadata to construct that. Only the new metadata is 
contained in the file system.

You also need an archive structure which contains deletion records. AFAIK 
tar, cpio etc don't handle that.

I don't know. Is that question relevant to this list? Are you offering to 
sponsor the development of the features you find missing?

Or are you complaining because the gift you received isn't exactly what 
you want?
