Zumastor 0.7 (Stable branch)
The Zumastor Linux storage project adds enterprise storage features to Linux, primarily improved snapshots and remote replication. Point-in-time, near zero-cost, block level snapshots can be added to any existing filesystem and performance does not degrade with multiple snapshots. Remote replication is achieved by sending minimal block level deltas between snapshots without having to traverse the entire filesystem like rsync does. License: GNU General Public License (GPL) Changes:
This release adds an experimental "revert to snapshot" feature, an experimental "multilayer replication" feature (e.g. for doing star topology software distribution), and lets downstream replicas retain snapshots (which is of importance when using the system as part of a backup scheme).Image

NAME

       snapconv - Sinclair ZX Spectrum snapshot converter

SYNOPSIS

       snapconv [ -c ] [ -n ] infile outfile

DESCRIPTION

       snapconv converts between ZX Spectrum snapshot files.

OPTIONS

       -c     specifies  that  all data in the output snapshot should be compressed, even if that compression will result in a bigger file than if
	      some data is left uncompressed. This helps compatibility with some buggy programs that can only read entirely compressed .z80 files.

       -n     specifies that the output snapshot should be uncompressed.

       -f     specifies that the A and F and A' and F' registers should be swapped.  Version 0.5.0 and older of  libspectrum(3)  had  a  bug  that
	      resulted	in  these registers being swapped in SZX snapshots only. Version 0.5.1 and newer of libspectrum(3) automatically recognise
	      these snapshots and correct the problem, but this flag is necessary to fix some snapshots created by development	versions  only	of
	      libspectrum(3) which had the bug fixed, but cannot be distinguished from snapshots containing the bug.

       infile specifies the snapshot to be converted. This file can be in any of the snapshot formats supported by libspectrum(3).

       outfile
	      specifies  the  output snapshot. The format will be determined by the file extension and can be in any of the formats libspectrum(3)
	      supports for output.

BUGS

       None known.
