-The Samba project is over 10 years old. During the early history
-of Samba, UNIX administrators were its key implementors. UNIX administrators
-use UNIX system tools to backup UNIX system files. Over the past
-4 years, an increasing number of Microsoft network administrators have
-taken an interest in Samba. This is reflected in the questions about backup
-in general on the Samba mailing lists.

-During discussions at a Microsoft Windows training course, one of
-the pro-UNIX delegates stunned the class when he pointed out that Windows
-NT4 is limiting compared with UNIX. He likened UNIX to a Meccano set
-that has an unlimited number of tools that are simple, efficient,
-and, in combination, capable of achieving any desired outcome.
-</p><p>
-<a class="indexterm" name="id433972"></a>
-<a class="indexterm" name="id433978"></a>
-One of the Windows networking advocates retorted that if she wanted a
-Meccano set, she would buy one. She made it clear that a complex single
-tool that does more than is needed but does it with a clear purpose and
-intent is preferred by some like her.

- BackupPC version 2.0.0 has been released on <a class="ulink" href="http://backuppc.sourceforge.net" target="_top">SourceForge</a>.
- New features include support for <code class="literal">rsync/rsyncd</code> and internationalization of the CGI interface
- (including English, French, Spanish, and German).

- BackupPC is a high-performance Perl-based package for backing up Linux,
- UNIX, and Windows PCs and laptops to a server's disk. BackupPC is highly
- configurable and easy to install and maintain. SMB (via smbclient),
- <code class="literal">tar</code> over <code class="literal">rsh/ssh</code>, or <code class="literal">rsync/rsyncd</code>
- are used to extract client data.

- Given the ever-decreasing cost of disks and RAID systems, it is now
- practical and cost effective to backup a large number of machines onto
- a server's local disk or network storage. This is what BackupPC does.
- </p><p>
- Key features are pooling of identical files (big savings in server disk
- space), compression, and a comprehensive CGI interface that allows users
- to browse backups and restore files.
- </p><p>
-<a class="indexterm" name="id434182"></a>
- BackupPC is free software distributed under a GNU GPL license.
- BackupPC runs on Linux/UNIX/freenix servers and has been tested
- on Linux, UNIX, Windows 9x/Me, Windows 98, Windows 200x, Windows XP, and Mac OSX clients.

- <code class="literal">rsync</code> is a flexible program for efficiently copying files or

- The rsync remote-update protocol allows rsync to transfer just
- the differences between two sets of files across the network link,
- using an efficient checksum-search algorithm described in the
- technical report that accompanies the rsync package.</p><p>Some of the additional features of rsync are:</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>
- Support for copying links, devices, owners, groups, and permissions.
- </p></li><li class="listitem"><p>

- </p></li><li class="listitem"><p>
- A CVS exclude mode for ignoring the same files that CVS would ignore.

- Can use any transparent remote shell, including rsh or ssh.

- Amanda, the Advanced Maryland Automatic Network Disk Archiver, is a backup system that
- allows the administrator of a LAN to set up a single master backup server to back up
- multiple hosts to a single large capacity tape drive. Amanda uses native dump and/or
- GNU tar facilities and can back up a large number of workstations running multiple
- versions of UNIX. Recent versions can also use Samba to back up Microsoft Windows hosts.
