After publicly bitching about Linux's poor backup infrastructure for the
hundredth time, I decided to write a common system for making snapshots.
I've written the first iteration in bash. It took one day to do most of
the work, and then a few hours of testing and fixing to get things
working reasonably well.
https://bitbucket.org/gordonmessmer/dragonsdawn-snapshot
At this point, there's enough working for other people to start looking
at. Systems with ext3/4 filesystems on LVM are supported. btrfs will
follow. PostgreSQL has a script to make its data consistent, but other
common systems like MySQL, OpenLDAP, and 389 DS need similar support.
Documentation needs to be written. A few architectural issues need to
be ironed out.
If you're interested in improving the state of backups on GNU/Linux,
please have a look and contact me if you want to help with code,
testing, documentation, packaging, or maintaining packages in Fedora. I
would very much like to see this project become a standard feature of
GNU/Linux installs.
