rsybak - Backup files/directories with histories, using rsync
This document describes version 0.25 of rsybak (from Perl distribution File-RsyBak), released on 2015-04-22.
Usage:
% rsybak [options] <source> <target>
Examples:
% rsybak /home/jajang/mydata /backup/jajang/mydata
This script has shell tab completion capability with support for several shells.
To activate bash completion for this script, put:
complete -C rsybak rsybak
in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.
~/.bashrc
It is recommended, however, that you install shcompgen which allows you to activate completion scripts for several kinds of scripts on multiple shells. Some CPAN distributions (those that are built with Dist::Zilla::Plugin::GenShellCompletion) will even automatically enable shell completion for their included scripts (using shcompgen) at installation time, so you can immadiately have tab completion.
shcompgen
To activate tcsh completion for this script, put:
complete rsybak 'p/*/`rsybak`/'
in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.
~/.tcshrc
It is also recommended to install shcompgen (see above).
For fish and zsh, install shcompgen as described above.
Specify additional command-line options
This script can read configuration file, which by default is searched at ~/.config/.conf, ~/.conf or /etc/.conf (can be changed by specifying --config-path). All found files will be read and merged.
~/.config/.conf
~/.conf
/etc/.conf
--config-path
To disable searching for configuration files, pass --no-config.
--no-config
Configuration file is in the format of IOD, which is basically INI with some extra features.
You can put multiple profiles in a single file by using section names like [profile=SOMENAME]. Those sections will only be read if you specify the matching --config-profile SOMENAME.
[profile=SOMENAME]
--config-profile SOMENAME
List of available configuration parameters:
backup (see --no-backup) extra_dir (see --extra-dir) extra_rsync_opts (see --extra-rsync-opts) format (see --format) format_options (see --format-options) histories (see --histories) rotate (see --no-rotate) source (see --source) target (see --target)

Set path to configuration file.
Can be specified multiple times.
Set configuration profile to use.
Do not use any configuration file.
Do not read environment for default options.
Pass options to formatter.
Choose output format, e.g. json, text.
Default value:
undef
Equivalent to --format=json-pretty.
Whether to force creation of source directory in target.
If set to 1, then backup(source => '/a', target => '/backup/a') will create another 'a' directory in target, i.e. /backup/a/current/a. Otherwise, contents of a/ will be directly copied under /backup/a/current/.
Will always be set to 1 if source is more than one, but default to 0 if source is a single directory. You can set this to 1 to so that behaviour when there is a single source is the same as behaviour when there are several sources.
Pass extra options to rsync command (JSON-encoded).
See --extra-rsync-opts.
--extra-rsync-opts
Pass extra options to rsync command (YAML-encoded).
Pass extra options to rsync command.
Extra options to pass to rsync command when doing backup. Note that the options will be shell quoted, , so you should pass it unquoted, e.g. ['--exclude', '/Program Files'].
Display help message and exit.

See --histories.
--histories
Histories/history levels (YAML-encoded).
Histories/history levels.
[-7,4,3]
Specifies number of backup histories to keep for level 1, 2, and so on. If number is negative, specifies number of days to keep instead (regardless of number of histories).
If backup=1 and rotate=0 then will only create new backup without rotating histories.
If backup=0 and rotate=1 then will only do history rotating.
