zpaqfranz - Man Page

zpaqfranz command archive[.zpaq] [files|directory]... [-switches]...

zpaqfranz is like 7z or RAR on steroids, with versions/"snapshots"

 Conceptually similar to Mac time machine, but much more efficiently
 Keeps backup always-to-always, no need to ever prune (CryptoLocker)
 Easily handles millions of files and TBs of data, non-latin support
 Cloud backups with full encryption, minimal data transfer/bandwidth
 Data integrity check CRC32+XXHASH|SHA-1|SHA-2|SHA-3|MD5|XXH3|BLAKE3
 Thorough data verification, multithread support (real world 1GB+/s)
 Specific zfs handling functions,full multiplatform interoperability
 Particularly suitable for minimal space storage of virtual machines

 Windows, FreeBSD, OpenBSD, Linux, MacOS, Solaris, OmniOS and others

archive assume by default a .zpaq extension.

If archive contains wildcards * or ?, then the archive is multipart, where * matches the part number and ? matches single digits. The concatenation starts from 1.
For example, arc?? would match the concatenation of
arc01.zpaq,
arc02.zpaq,
arc03.zpaq (...)
until the last one.
DO NOT FORGET THE DOUBLE QUOTEs!

 Running on "weird things" requires compiling with the right switches 
 -DNOJIT           : Not-Intel CPU (ex. Apple M1/M2, ARM...)
 -DSOLARIS         : Solaris-based OS
 -DANCIENT         : Very old system (cheap NAS...)
 -DBIG             : BIG ENDIAN
 -DESX             : ESXi server
 -DALIGNMALLOC     : Enforce mem alignment (sparc64...)
 -DHWSHA2          : Enable HW SHA support (Ryzen...)

 Use the autotest command if necessary.
 
 If the executable is named "dir" act (just about)... like Windows' dir

 If the executable is named "robocopy" runs... some kind of robocopy-like
 WET RUNS (-kill automagically enabled), with -space enabled.
 ex robocopy /tmp/zp /tmp/backup1 /tmp/backup2

 zpaqfranz currently does not store owner/group (it will be in the future).
 If you really need you must use tar.
 
 "Strange" systems with little memory (NAS, ESX servers...) can crash.

 zpaqfranz supports -stdin and -stdout (zpaq does not)
