Project files are stored in a version repository, a backup and an archive.

                                                                       +---------+

non-versioned files

Files which are non-versioned, are actually ignored by the versioning program. But I do want to have a back-up of these non-versioned files, unless they can be generated by the versioned files. Subversion holds a list of the non-versioned files:

svn status --no-ignore | grep "^I"

but Subversion makes no distinction between generated and non-generated files. Is is useful to check which ignored files have changed after a certain date?

This backup thing is becoming way to complicated and unreliable. I want to be able to rely on full backups, and since I'm going to keep a machine running 24/7 I should be able to make a full backup each night.

Trying Disk ARchive.

No more complicated semantic differences between 'archive' and 'back-up'; they're synonyms.

I'm creating a back-up of data only. My theory is I don't need a back-up of the OS, since it can be re-installed easily from scratch. This is true if only if I am persistent in copying modified OS configuration files to my data area...

Want to encrypt backup, but dar says:

Aborting program. The requested operation needs a feature that has been disabled at compilation time: blowfish strong encryption support
