One feature I couldn’t live without anymore is snapshots. As system administrators, we often find ourselves in situations where we’ve made a mistake, need to revert to a previous state, or need access to a log that has been rotated and disappeared. Since I started using ZFS, all of this has become incredibly simple, and I feel much more at ease when making any modifications.
However, since I don’t always remember to create a manual snapshot before starting to work, I use an automatic snapshot system. For this type of snapshot, I use the excellent
↫ Stefano Marinellizfs-autobackuptool – which I also use for backups. The goal is to have a single, flexible, and configurable tool without having to learn different syntaxes.
I’m always a little sad about the fact that the kind of advanced features modern file systems like ZFS, btrfs, and others offer are so inaccessible to mere desktop users like myself. While I understand they’re primarily designed for server use, they’re still making their way to desktops – my Fedora installations all default to btrfs – and I’d love to be able to make use of their advanced features straight from within KDE (or GNOME or whatever it is you use).
Of course, that’s neither here or there for the article at hand, which will be quite useful for people administering FreeBSD and/or Linux systems, and who would like to get the most out of ZFS by automating some of its functionality.
