Various programs and scripts use rsync to provide hardlinked backups.
See, for example, Mike Rubel's site (L<http://www.mikerubel.org>),

BackupPC provides many additional features, such as compressed storage,
hardlinking any matching files (rather than just files with the same name),
and storing special files without root privileges. But these other scripts

directories change. For example, if you are backing up a DMZ machine,
you could request that you get sent email if any files below /bin,

-Disconnect the notion of a physical host and a backup client.
-Currently there is a one-to-one match between physical hosts
-and backup clients. Instead, the current notion of a host
-should be replaced by a backup client. Each backup client
-corresponds to a physical host. A physical host could have
-several backup clients. This is useful for backing up
-different types of data, or backing up different portions
-of a machine with different frequencies or settings.

-Resuming incomplete full backups. Useful if a machine
-(eg: laptop) is disconnected from the network during a backup,
-or if the user manually stops a backup. This would be supported
-initially for rsync. The partial dump would be kept, and be
-browsable. When the next dump starts, an incremental against
-the partial dump would be done to make sure it was up to date,
-and then the rest of the full dump would be done.

Replacing smbclient with the perl module FileSys::SmbClient. This
gives much more direct control of the smb transfer, allowing
incrementals to depend on any attribute change (eg: exist, mtime,

-Add a backup browsing feature that shows backup history by file.
-So rather than a single directory view, it would be a table showing
-the files (down) and the backups (across). The internal hardlinks
-encode which files are identical across backups. You could immediately
-see which files changed on which backups.

More speculative: Storing binary file deltas (in fact, reverse deltas)
for files that have the same name as a previous backup, but that aren't
already in the pool. This will save storage for things like mailbox

L<Limitations|limitations> section for more discussion of this problem.
+In addition to total disk space, you shold make sure you have
+plenty of inodes on your BackupPC data partition. Some users have
+reported running out of inodes on their BackupPC data partition.
+So even if you have plenty of disk space, BackupPC will report
+failures when the inodes are exhausted. This is a particular
+problem with ext2/ext3 file systems that have a fixed number of
+inodes when the file system is built. Use "df -i" to see your

There are other optimizations and options with mod_perl. For
example, you can tell mod_perl to preload various perl modules,
set to 'archive'. This allows for multiple configurations at sites where
there might be a combination of tape and cd/dvd backups being made.
+BackupPC provides a menu that allows one or more hosts to be archived.
+The most recent backup of each host is archived using BackupPC_tarCreate,
+and the output is optionally compressed and split into fixed-sized
+files (eg: 650MB).
+
+The archive for each host is done by default using
+__INSTALLDIR__/BackupPC_archiveHost. This script can be copied
+and customized as needed.

-Tape archive. The programs are called BackupPC_archivecd and
