Key differences against ZPAQ 7.15

  1. First goal: doveryay, no proveryay (trust, but verify). As a storage manager I need to be sure that my backups are perfect, so 'verify' is the objective of my zpaq fork.

  2. Second: do not break compatibility with 7.15. Although hard, it is important that the archive format does not change. Reference decompressor

  3. Third: most useful output: 7.15 is often cryptic but not very useful.

  4. Fourth: pack everything needed for a storage manager (compare directories, hashing, duplicate find, fix of utf-8 filenames, wiping etc) in a single program with a single source cpp.

  5. Fifth: 'smart' support for strange filenames and paths, Windows and non-Windows. It is not always trivial to restore files from Unix to Windows

  6. Sixth: smooth with ZFS (I almost always use FreeBSD servers)

  7. Seventh: run on multiple systems commonly used in storage (ESXi, non-Intel QNAP NAS).
