Backup for (Ubuntu) Linux

During all my toils of getting my development machine back up working (laptop using Eclipse to do a little Android development) I have been doing a lot of backups. And have had to struggle with it.

So where are the easy backup solutions for (Ubuntu) Linux lurking about? I need to do a backup to (and restore from) external media CDs or DVDs, preferably RWs. Which software handles that easily including blanking said RW medias, including DVD+RWs. And preferably is able to do multi-volume backups.

At this time I do not have a set backup routine for my pictures, mail, videos, etc. I do use Ubuntu One for some things but am limited to the free version and thus only 2 GB. So it is basically Ad Hoc backup for me.

Anybody have any good backup solutions? Please post in comments! (comments are no longer moderated in new (< 14 day old) posts)

HomeServer Part 2 - Planning continued

The requirements for my particular HomeServer are as follows:

• Firewall (including routing of possible multiple networks)
• Virtual Private Networking
• E-mail scanning
• Intrusion Detection
• SMB storage for Windows boxes
• NFS storage for *nix boxes
• Backup of above storage
• HTTP Proxying
• Web server with server side scripting (for administration module + development of dynamic web pages)
• Database (for development of database driven websites)

Hardware requirements:

The firewall in itself does not require much in system hardware. My Pentium 133 had only 32MB of memory and an 8 GB harddrive. and it had an idle rate of more than 98 per cent. Running multiple VPN connection *will* need processing power.

The HTTP Proxy database and the webserver will need plenty of memory - the more the merrier.

The storage area (which will be accessible from both *nix (NFS) and (Windows) needs space and preferably the infrastructure to run with some kind of redundancy. Again the more memory that is available, the bigger th chance will be that the required piece of storage will be in memory.

Backup will be burned onto CD and DVD.

As I don't have any funds that will influeence the hardware setup. The current storage is an 8 GB harddrive. the CPU an older Pentium

Personal note : I will be out all day tomorrow attending a wedding so there will only be a small blog if any.
