BackupPC saves backups onto disk. Because of pooling you can relatively

At some sites the disk-based backup will be adequate, without a
secondary tape backup. This system is robust to any single failure: if a
of the server disk failing can be made very small by spending more money
on increasingly better RAID systems.

To use rsync and rsyncd with BackupPC you will need to install File::RsyncP.
You can run "perldoc File::RsyncP" to see if this module is installed.

=head2 Step 5: Client Setup
-Two methods for getting backup data from a client are
-supported: smb and tar. Smb is the preferred method for WinXX clients
-and tar is preferred method for linux/unix clients.
+Two methods for getting backup data from a client are supported: smb and
+tar. Smb is the preferred method for WinXX clients and tar is preferred
+method for linux/unix clients.
The transfer method is set using the $Conf{XferMethod} configuration
setting. If you have a mixed environment (ie: you will use smb for some
prepared to run rsync/cygwin on your WinXX client. More information
about this will be provided via the FAQ.)
-You need to create shares for the data you want to backup.
-Open "My Computer", right click on the drive (eg: C), and
-select "Sharing..." (or select "Properties" and select the
-"Sharing" tab). In this dialog box you can enable sharing,
-select the share name and permissions.
+If you want to use rsyncd for WinXX clients you can find a pre-packaged
+zip file on L<http://backuppc.sourceforge.net>. The package is called
+cygwin-rsync. It contains rsync.exe, template setup files and the
+minimal set of cygwin libraries for everything to run. The README file
+contains instructions for running rsync as a service, so it starts
+automatically everytime you boot your machine.
+
+Otherwise, to use SMB, you need to create shares for the data you want
+to backup. Open "My Computer", right click on the drive (eg: C), and
+select "Sharing..." (or select "Properties" and select the "Sharing"
+tab). In this dialog box you can enable sharing, select the share name
+and permissions. Many machines will be configured by default to share
+the entire C drive as C$ using the administrator password.
If this machine uses DHCP you will also need to make sure the
NetBios name is set. Go to Control Panel|System|Network Identification
Each of these programs reside in __INSTALLDIR__/bin.
+=head1 Archive functions
+
+BackupPC supports archiving to removable media. For users that require
+offsite backups, BackupPC can create archives that stream to tape
+devices, or create files of specified sizes to fit onto cd or dvd media.
+
+Each archive type is specified by a BackupPC host with its XferMethod
+set to 'archive'. This allows for multiple configurations at sites where
+there might be a combination of tape and cd/dvd backups being made.
+
+=head2 Configuring an Archive Host
+
+To create an Archive Host, add it to the hosts file just as any other host
+and call it a name that best describes the type of archive, e.g. ArchiveDLT
+
+To tell BackupPC that the Host is for Archives, create a config.pl file in
+the Archive Hosts's pc directory, adding the following line:
+
+$Conf{XferMethod} = 'archive';
+
+To further customise the archive's parameters you can adding the changed
+parameters in the host's config.pl file. The parameters are explained in the config.pl
+file.
+
+The example archive programs included with BackupPC are for a CD and
+Tape archive. The programs are called BackupPC_archivecd and
+BackupPC_archivetape. These are specified by the ArchiveClientCmd configuration
+parameter.
+
+=head2 Starting an Archive
+
+In the web interface, click on the Archive Host you wish to use. You will see a
+list of previous archives and a summary on each. By clicking the "Start Archive"
+button you are presented with the list of hosts and the approximate backup size
+(note this is raw size, not projected compressed size) Select the hosts you wish
+to archive and press the "Archive Selected Hosts" button.
+
+The next screen allows you to adjust the parameters for this archive run.
+Press the "Start the Archive" to start archiving the selected hosts with the
+parameters displayed.
