+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.

+<a class="indexterm" name="id2638059"></a>
+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="id2638075"></a>
+<a class="indexterm" name="id2638082"></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 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),
+ <span><strong class="command">tar</strong></span> over <span><strong class="command">rsh/ssh</strong></span>, or <span><strong class="command">rsync/rsyncd</strong></span>
+ are used to extract client data.

+<a class="indexterm" name="id2638273"></a>
+<a class="indexterm" name="id2638280"></a>
+ 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>

+ 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.

+ Exclude and exclude-from options are similar to GNU tar.

+ 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.
