SYNOPSIS

9       rdiffdir [options] sig[nature] basis_dir signature_file
10
11       rdiffdir [options] delta full_sigtar {incr_sigtar} new_dir delta_file
12
13       rdiffdir [options] patch basis_dir delta_file
14
15       rdiffdir [options] tar basis_dir tar_file
16
17       If signature_file or delta_file are "-", the data will be read from
18       stdin or written to stdout as appropriate.

DESCRIPTION

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.

OPTIONS

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.

SELECTION OPTIONS

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.

BUGS

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.
