65 e.g. Mac OS.
66
67 ------------------
68 0.1.4 (2010-11-08)
69 ------------------
70 This version of dss contains some new features, many improvements of
71 existing features and several bug fixes.
72
73 Support for resuming snapshot creation after restart has been added
74 and snapshot removal is deferred until at least one current snapshot
75 exists. The internal handling of the various hooks has been simplified
76 and many error messages have been clarified. On SIGHUP, dss now writes
77 its configuration and internal state to the log file.
78
79 ------------------
80 0.1.3 (2009-06-06)
81 ------------------
82 You can now specify pre-rm/post-rm-hooks that are executed whenever
83 a snapshot is deleted. This release adds better compatibility with
84 rsync 3.0, and avoids busy loops when automatically restarting the
85 rsync process.
86
87 ------------------
88 0.1.2 (2009-03-05)
89 ------------------
90 This release includes the reason why a snapshot gets removed in the
91 log message. It will never remove the snapshot that is currently
92 being created. It will really pass the full path to the last complete
93 snapshot in the post_create_hook.
94
95 ------------------
96 0.1.1 (2008-11-13)
97 ------------------
98 This release prevents busy loops on rsync exit code 13. It ignores
99 any snapshot directory with creation time >= completion time. It
100 opens /dev/null for reading and writing when executing rsync. It shows
101 human readable snapshot creation duration when listing snapshots. It
102 restarts the rsync process if it returned with exit code 13.
103
104 ------------------
105 0.1.0 (2008-10-10)
106 ------------------
107 Initial public release.
