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

Sure, but to create such a thing, you need a considerably more=20
sophisticated process for creating incremental backups. The 'standard=20
procedure' backs up all data created or modified since the last full=20
backup. You only need the metadata of all the current data to do that, and=
=20
that's all in the file system.

You want deletion records for all data deleted since the last backup. You=
=20
need both old and new metadata to construct that. Only the new metadata is=
=20
contained in the file system.

You also need an archive structure which contains deletion records. AFAIK=
=20
tar, cpio etc don't handle that.

I don't know. Is that question relevant to this list? Are you offering to=
=20
sponsor the development of the features you find missing?

Or are you complaining because the gift you received isn't exactly what=20
you want?
