rdiffdir1

Usage

Overview

rdiffdir is supposed to be like rdiff, but can operate on directories. See rdiff(1) for more information. The syntax is similar.

Regarding the delta command, the full_sigtar operand is a signature_file written by an earlier signature or tar command (the latter using the --write-sig-to option). The optional incr_sigtar operands are signature files written by earlier delta commands using the --write-sig-to option. This way the Nth invocation of the delta command can parse (and extend) the signature chain that has been founded by the first signature or tar command with a full signature, and then extended by the subsequent N-1 delta invocations with incremental signatures. It is the responsibility of the user to specify the sigtar operands in logical increment order.

Options

--write-sig-to sigfile

This option is only used in delta and tar modes. When specified, rdiffdir will write a signature of the directory it is processing to sigfile. The end result will be a delta and a new signature calculated over the same data.

-z, --gzip-compress

Enable gzip compression and decompression of signature and delta files.

Options

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