The new minor release v2.1.0 is available!
Dumpnet was now tested on SuSE, Fedora & Debian Linux, FreeBSD, OpenBSD, Solaris and Cygwin (Windows).
now also includes sample target host configurations not just for Linux und Cygwin but also for FreeBSD, OpenBSD and Solaris.
NEW MODULE: dumpnet.host.fstab.rsync! It uses rsync(1) with
it's --link-dest option. This will create hard links from the
directory of the last successful backup to the current destination
directory for unchanged files. Files with changed ownership or
permissions will not be linked. Much less storage capacity is required
on the dumpnet host as unchanged files are physically stored only once.
The downside is that if you mess up one file, multiple hard links
pointing to this file will be affected.
See http://www.mikerubel.org/computers/rsync_snapshots/ for a more
detailed description of the whole problem.
moved development to sourceforge's CVS server
lots of small fixes

What is dumpnet?
|
dumpnet is a collection of bash scripts that allows you to backup multiple servers simultaneously.
You can do incremental file system dumps with tar, dump and rsync, backup databases and much more.
AIDE can also easily be integrated.
Major Features:
1.
Dumpnet is implemented in bash scripts only.
2.
It's a hard disk based backup solution - no tapes are
necessary.
3.
The backup machine on which dumpnet is installed func-
tions as a SSH client while the target hosts (the
hosts to be backuped) function as SSH servers. Public
key authentication is used.
4.
Due to the use of SSH all traffic between the backup
machine and the target hosts is encrypted and can be
run over the Internet.
5.
Dumpnet only needs to be installed on the backup
machine.
6.
Dumpnet is flexible and highly configurable.
7.
Incremental filesystem backups can be done easily
using dump, tar or rsync.
8.
Integration of auditing and intrusion detection tools
such as AIDE (Advanced Intrusion Detection Environ-
ment) and nmap.
9.
Full support for sudo - no remote root login is
required.
10.
The report generated about a backup session can be
sent via email. Encryption using GnuPG is supported.
11.
It provides extensive logging.
12.
Dumpnet was tested on SuSE, Fedora & Debian Linux,
FreeBSD, OpenBSD, Solaris and Cygwin (Windows).
