But sometimes you do need to 'package', and the fact that we use RPM files to package/bundle up a set of files and some metadata is an example of that.
The guts of a RPM file is gzip'd CPIO/SVR4 format file. More recent versions of RPM can also use bzip2, lzip, lzma, or xz compression.
But 1) this is not a backup, and 2) there is a checksum.
Checksums are good. It doesn't matter whether they are on the result of a rsync or are for a bundled package.
And why should you not use a RPM format for bundling up a collection of files that constitute a backup? Isn't that what, in effect, they are used for anyway? Don't you see they symmetry?
You don't understand. A backup is something you rely on for recovery in case of disaster. It has to be reliable, and has to last long. An rpm is not critical. If the download went bad, the checksum notices and you can download it again. If there was an error in creation, the users complain and it is created again. A backup can not be created again if bad. They are different use cases. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
