What things are you trying to backup?

I wrote one I've been using to manage a few TB of disk-to-disk backups: http://www.effortlessis.com/backupbuddy/
Hope it helps.

If you're looking at backing up to Tape, AMANDA is a great solution, we use it at work and haven't had problems with her. www.amanda.org is the website if you wanted to check it out.

another supposedly-reasonable solution is called "bacula" (i have not used it).
A great solution for backing up to a remote disk is backuppc, which i do use and i love.

Guys, the more I use backuppc, the more I like it :)
http://backuppc.sourceforge.net/
Though it is a PITA to get configured ... once it is working, it is quite flexible. I am working on a CentOS RPM for extras, but it is also a PITA to fix the configurations for the RPM too :)
Hopefully an RPM soon.

Huh, I didn't find it to be difficult at all.
The install script sets a few particular config values for you, but really you should read the config.pl file and check things out for yourself. This takes half an hour.
the one thing i did run into that i didn't like was that the per-host config.pl file overrode the exclude value in the global config.pl file, rather than allowing you to append to that value.
using rsync as the transfer method, the actual implementation was pretty much trivial once i configured it.
Maybe if you're doing backups of windows PCs there's something harder about it (i'm sure ;).
ONe gotcha i ran into - on a backup client running x64 RHEL4 , the /var/log/lastlog file was a sparse file (as normal) but it was insanely large (presumably due to 64-bit data structures), and the default config for backuppc did not tell rsync to handle sparse files. I excluded the file from backups on that host rather than hack the rsync options, i didn't know if there was some good reason not to do sparse-file handling.
The only other likely gotcha i can think of is that rsync's memory usage rises linearly with the number of files being backed up, so on a machine with lots and lots of files (mail server using maildir mailboxes comes to mind), rsync will use immense amounts of memory, and you might have to split the backup job up into smaller pieces so that the backup client doesn't start swapping while it's running the backup. This is an rsync problem, not a backuppc problem per se, but i've seen a couple complaints of it on the backuppc mailing list in the few weeks i've been there.

The main problem there is that a long-standing bug in Cygwin keeps rsync-started-by-sshd from working. It starts up but after a short time both ends hang waiting for each other. You can do a standalone rsync running in daemon mode but it takes more client setup.
Does anyone here do Cygwin development or know the right person to beg for a bugfix?

Why don't people simply write a 10-line script for it ?
- - Use mt to see if the tape is online - - Use for to get all the dirs/filesystems you want - Write to the tape with dump - - Use mt to rewind and eject
And thats it.

Backuppc can back up all the machines on your network, keeping multiple copies on line with a clever scheme of compression and duplicate linking to keep much more (like 10x) than you'd expect on-line. It has a nice web interface to browse and restore and a concept of machine 'owners' so non-admin users can see only their own backups.
