22 rdiffdir is supposed to be like rdiff, but can operate on directories.
23 See rdiff(1) for more information. The syntax is similar.
24
25 Regarding the delta command, the full_sigtar operand is a
26 signature_file written by an earlier signature or tar command (the
27 latter using the --write-sig-to option). The optional incr_sigtar
28 operands are signature files written by earlier delta commands using
29 the --write-sig-to option. This way the Nth invocation of the delta
30 command can parse (and extend) the signature chain that has been
31 founded by the first signature or tar command with a full signature,
32 and then extended by the subsequent N-1 delta invocations with
33 incremental signatures. It is the responsibility of the user to specify
34 the sigtar operands in logical increment order.
35
36
38 --write-sig-to sigfile
39 This option is only used in delta and tar modes. When
40 specified, rdiffdir will write a signature of the directory it
41 is processing to sigfile. The end result will be a delta and a
42 new signature calculated over the same data.
43
44
45 -z, --gzip-compress
46 Enable gzip compression and decompression of signature and delta
47 files.
48

51 In signature and delta modes, rdiffdir accepts duplicity-like selection
52 options including --exclude, --exclude-filelist, etc. See the
53 duplicity(1) manual page for more information.

57 Hard links are currently unsupported (they will be treated as non-
58 linked regular files).
59
60 Bad signatures will be treated as empty instead of logging appropriate
61 error message.

72 Also we'd like to thank everybody posting issues to the mailing list or
73 on launchpad, sending in patches or contributing otherwise. Duplicity
74 wouldn't be as stable and useful if it weren't for you.
75
76 A special thanks goes to rsync.net, a Cloud Storage provider with
77 explicit support for duplicity, for several monetary donations and for
78 providing a special "duplicity friends" rate for their offsite backup
79 service. Email info@rsync.net for details.
