CVS README - Notes for people checking out of CVS
-------------------------------------------------
Getting rdiff-backup to run:
----------------------------
If you want to run a version of rdiff-backup checked out of CVS into
your $RDB_CVS directory, change to $RDB_CVS/rdiff_backup and run the
./compilec.py file:
cd $RDB_CVS/rdiff_backup; python compilec.py
With any luck, _librsync.so and C.so libraries will appear in that
directory. Then run rdiff-backup, making sure that all the files are
in your PYTHONPATH:
PYTHONPATH=$RDB_CVS $RDB_CVS/rdiff-backup <arguments>
Running the unit tests:
-----------------------
If you want to try some of tests, you first have to get the
testfiles.tar.gz tarball. It is available at
http://rdiff-backup.stanford.edu/testfiles.tar.gz
To untar it, root is required because the tarball contains device
files, files with various uid/gid, etc. If you don't have root, it's
ok, all the tests except for roottest.py may still work.
So, three steps:
1) Make sure the the C modules are compiled as explained above:
cd $RDB_CVS/rdiff_backup; python compilec.py
2) Untar the testfiles tarball, as root if you have it:
cd $RDB_CVS/testing; tar -xvzf testfiles.tar.gz
3) In the testing directory, run each of the *test.py files as
desired. For instance,
cd $RDB_CVS/testing; python rpathtest.py
If python restoretest.py doesn't work, try running
./makerestoretest3
Note:
- some of the tests may require a normal user ben and group ben to exist.
- you may need to install extra packages for acl/xattr... (such as
python-pylibacl and python-pyxattr on debian)

INSTALLATION:
Thank you for trying rdiff-backup. To install, run:
python setup.py install
The build process can be also be run separately:
python setup.py build
The default prefix is generally /usr, so files would be put in /usr/bin,
/usr/share/man/, etc. An alternate prefix can be specified using the
--prefix=<prefix> option. For example:
python setup.py install --prefix=/usr/local
The default prefix depends on how you (or your distribution) installed and
configured Python. Suggested reading is "How installation works" from the
Python docs, which includes commands to determine your default prefix:
http://docs.python.org/install/index.html#how-installation-works
The setup script expects to find librsync headers and libraries in the
default location, usually /usr/include and /usr/lib. If you want the
setup script to check different locations, use the --librsync-dir
switch or the LIBRSYNC_DIR environment variable. For instance,
python setup.py --librsync-dir=/usr/local build
instructs the setup program to look in /usr/local/include and
/usr/local/lib for the librsync files.
Finally, the --lflags and --libs options, and the LFLAGS and LIBS
environment variables are also recognized. Running setup.py with no
arguments will display some help. Additional help is displayed by the
command:
python setup.py install --help
More information about using setup.py and how rdiff-backup is installed
is available from the Python guide, Installing Python Modules for System
Administrators, located at http://docs.python.org/install/index.html
NB: There is no uninstall command provided by the Python distutils system.
One strategy is to use the python setup.py install --record <file> option
to save a list of the files installed to <file>.
To build from source on Windows, you can use the command:
python setup.py py2exe --single-file
to build a single executable file which contains Python, librsync, and
all required modules.
REQUIREMENTS:
Remember that you must have Python 2.2 or later and librsync 0.9.7 or
later installed. For Python, see http://www.python.org. The
rdiff-backup homepage at http://rdiff-backup.nongnu.org/ should
have a recent version of librsync; otherwise see the librsync homepage
at http://librsync.sourceforge.net/. On Windows, you must have the
Python for Windows extensions installed if you are building from source.
The extensions can be downloaded from: http://pywin32.sourceforge.net/
If you are not building from source on Windows, you do not need Python
or librsync; they are bundled with the executable.
For remote operation, rdiff-backup should be installed and in the
PATH on remote system(s) (see man page for more information). On
Windows, if you are using the provided .exe binary, you must have an
SSH package installed for remote operation.
The python modules pylibacl and pyxattr are optional. If they are
installed and in the default pythonpath, rdiff-backup will support
access control lists and user extended attributes, provided the file
system(s) also support these features. Pylibacl and pyxattr can be
downloaded from http://pylibacl.sourceforge.net/ and
http://pyxattr.sourceforge.net/. Mac OS X users need a different
pyxattr module, which can be downloaded from
http://cheeseshop.python.org/pypi/xattr
If you want to use rdiff-backup-statistics, you must have Python 2.4
or later.
TROUBLESHOOTING:
If you have everything installed properly, and it still doesn't work,
see the enclosed FAQ.html, the web page at http://rdiff-backup.nongnu.org,
the Wiki at: http://wiki.rdiff-backup.org, and/or the mailing list.
The FAQ in particular is an important reference, especially if you are
using smbfs/CIFS, Windows, or have compiled by hand on Mac OS X.
Fix restore with --force over existing regular file.
For comparing, check source filesystem's abilities
Clean up compare reports
Test comparing of single files, and files/directories specified by
increment. Also test --include/--exclude with compare options.
---------[ Medium term ]---------------------------------------
Look into sparse file support (requested by Stelios K. Kyriacou)
Look at Kent Borg's suggestion for restore options and digests.
---------[ Long term ]---------------------------------------
Think about adding Gaudet's idea for keeping track of renamed files.
Look into different inode generation techniques (see treescan, Dean
Gaudet's other post).
INSTALLATION:
Thank you for trying rdiff-backup on Windows. Native support for the Windows
environment is quite new in rdiff-backup. Please read the manual page, FAQ and
the Wiki thorougly.
To install the provided binary, simply copy rdiff-backup.exe to someplace in
your PATH. Everything is included in the binary (including Python) for local
operation. For remote operation, you will need to install a Windows SSH
program. You will also need to install rdiff-backup on the remote system(s).
You will need the Microsoft Visual C++ 2008 redistributables. If these are
not installed on your system, rdiff-backup will be unable to run and Windows
will display a message such as "The system cannot execute the specified
program". To install the redistributables for all users, install the package
available from Microsoft.com (search for "visual c 2008 redistributable").
Alternatively, you can install the redistributable in a "side-by-side"
configuration, which does not require administrator privelges. Simply
download the DLL package from:
http://download.savannah.gnu.org/releases/rdiff-backup/Microsoft.VC90.zip
and copy the four enclosed files to the same directory as rdiff-backup.exe.
You will need to follow either method only once.
ADDITIONAL ISSUES:
Currently, rdiff-backup's --include and --exclude options do not support
Windows paths with \ as the directory separator. Instead, it is necessary to
use / which is the Unix directory separator.
Additionally, you may need to run rdiff-backup from the same directory as the
source of your backup, eg:
> cd c:\
> rdiff-backup.exe --include "c:/My Stuff" --exclude "c:/**" c:/ c:/Backup
will work to backup "c:\My Stuff" to "c:\Backup", but:
> cd "c:\My Stuff"
> rdiff-backup.exe --include "c:/My Stuff" --exclude "c:/**" c:/ c:/Backup
will not work. UPDATE: With appropriate escaping, it looks like it is
possible for this to work. Follow this example:
> mkdir c:\foo
> cd "c:\Documents and Settings"
> rdiff-backup.exe --include c:\\/foo --exclude c:\\/** c:\/ c:\bar
The \\ is necessary in the --include and --exclude options because those
options permit regular-expressions, and \ is the escape character in
regular-expressions, and thus needs to be escaped itself.
TROUBLESHOOTING:
If you have everything installed properly, and it still doesn't work,
see the enclosed manual, FAQ, the web page at http://rdiff-backup.nongnu.org,
the Wiki at: http://wiki.rdiff-backup.org, and/or the mailing list. You can

Summary: Convenient and transparent local/remote incremental mirror/backup
Name: rdiff-backup
Release: 1

Source: %{name}-%{version}.tar.gz

Patch: rdiff-backup-rh7x.patch
%description
rdiff-backup is a script, written in Python, that backs up one
directory to another and is intended to be run periodically (nightly
from cron for instance). The target directory ends up a copy of the
source directory, but extra reverse diffs are stored in the target
directory, so you can still recover files lost some time ago. The idea
is to combine the best features of a mirror and an incremental
backup. rdiff-backup can also operate in a bandwidth efficient manner
over a pipe, like rsync. Thus you can use rdiff-backup and ssh to
securely back a hard drive up to a remote location, and only the
differences from the previous backup will be transmitted.

Usage: compress-rdiff-backup-increments [options] mirror_directory
This script will compress the old rdiff-backup increments under
mirror_directory, in a format compatible with rdiff-backup version
0.7.1 and later. So for instance if you were using an old version
of rdiff-backup like this:
rdiff-backup /foo /backup
and now you want to take advantage of v0.7.1's space saving
compression, you can run:
compress-rdiff-backup-increments /backup
Options:
--rdiff-backup-location location
This script reads your rdiff-backup executable. The default
is "/usr/bin/rdiff-backup", so if your rdiff-backup is in a
different location, you must use this switch.
--no-compression-regexp regexp
Any increments whose base name match this regular expression
won't be compressed. This is generally used to avoid
compressing already compressed files. See the rdiff-backup
man page for the default.

.TH RDIFF-BACKUP-STATISTICS 1 "NOVEMBER 2006" "Version 1.1.6" "User Manuals" \" -*- nroff -*-
.SH NAME
rdiff-backup-statistics \- summarize rdiff-backup statistics files
.SH SYNOPSIS
.B rdiff-backup-statistics
.BI [\-\-begin-time " time" ]
.BI [\-\-end-time " time" ]
.BI [\-\-minimum-ratio " ratio" ]
.B [\-\-null-separator]
.B [\-\-quiet]
.I repository
.SH DESCRIPTION
.BI rdiff-backup-statistics
reads the matching statistics files in a backup repository made by
.B rdiff-backup
and prints some summary statistics to the screen. It does not alter
the repository in any way.
The required argument is the pathname of the root of an rdiff-backup
repository. For instance, if you ran "rdiff-backup in out", you could
later run "rdiff-backup-statistics out".
The output has two parts. The first is simply an average of the all
matching session_statistics files. The meaning of these fields is
explained in the FAQ included in the package, and also at
.IR http://rdiff-backup.nongnu.org/FAQ.html#statistics .
The second section lists some particularly significant files
(including directories). These files are either contain a lot of
data, take up increment space, or contain a lot of changed files. All
the files that are above the minimum ratio (default 5%) will be
listed.
If a file or directory is listed, its contributions are subtracted
from its parent. That is why the percentage listed after a directory
can be larger than the percentage of its parent. Without this, the
root directory would always be the largest, and the output would be
boring.
.SH OPTIONS
.TP
.BI \-\-begin-time " time"
Do not read statistics files older than
.IR time .
By default, all statistics files will be read.
.I time
should be in the same format taken by \-\-restore-as-of. (See
.B TIME FORMATS
in the rdiff-backup man page for details.)
.TP
.BI \-\-end-time " time"
Like
.B \-\-begin-time
but exclude statistics files later than
.IR time .
.TP
.BI \-\-minimum-ratio " ratio"
Print all directories contributing more than the given ratio to the
total. The default value is .05, or 5 percent.
.TP
.B \-\-null-separator
Specify that the lines of the file_statistics file are separated by
nulls (\\0). The default is to assume that newlines separate. Use
this switch if rdiff-backup was run with the \-\-null-separator when
making the given repository.
.TP
.B \-\-quiet
Suppress printing of the "Processing statistics from session..."
output lines.
.SH BUGS
When aggregating multiple statistics files, some directories above
(but close to) the minimum ratio may not be displayed. For this
reason, you may want to set the minimum-ratio lower than need.
