![]() ![]() What if you wanted to build a kiosk yourself? For having done a bunch of kiosk computers a few years ago, it's not an easy task, you need to think about: ATM are kiosks, most screens showing some information are also kiosks. You may have seen kiosk computers here and there, often wrapped in some kind of box with just a touch screen available. Tags:Ī kiosk, in the sysadmin jargon, is a computer that is restricted to a single program so anyone can use it for the sole provided purpose. It can also manage offline backups on a removable media and a few other non-simple cases. You can find more settings for this module in the man page configuration.nix.ītrbk is a powerful tool, as not only you can create snapshots with it, but it can stream them on a remote system with optional encryption. OPENGL DRIVER NOT ACCELERATED GZDOOM CODEHere is the code used to replicate the behavior of the code above. Rebuild your system, you should now have systemd units rvice and btrfs-snapshot.timer available.Īs the configuration file will be at the standard location, you can use btrbk as root to manually list or prune your snapshots in case you need to, like immediately reclaiming disk space.Īfter publishing this blog post, I realized a NixOS module existed to simplify the setup and provide more features. Snapshots will be made available under /.snapshots/. A SystemD service will be scheduled using a timer in order run btrbk run which handle snapshot creation and pruning. In the following example, we will keep the snapshots for 2 days, and create them every 10 minutes. The program btrbk is simple, it requires a configuration file /etc/nf defining which volume you want to snapshot regularly, where to make them accessible and how long you want to keep them. ![]() However, snapshots are superfast and cheap, and can be used to recover accidentally deleted files.ītrbk official website NixOS configuration § Backups are archives of your data that are on another device, and which can be used when the original device is lost/destroyed/corrupted. If your storage is damaged or the file system get corrupted, or the device stolen, you will lose your data. Snapshots are not backups! It is important to understand this. In the configuration, I'll show the code for NixOS using the tool btrbk to handle snapshots retention correctly. OPENGL DRIVER NOT ACCELERATED GZDOOM HOW TOToday, I'll demonstrate how to do something quite similar using BTRFS and regular snapshots. Comments on Fediverse/Mastodon Introduction §Īs shown in my previous article about the NILFS file system, continuous snapshots are great and practical as they can save you losing data accidentally between two backups jobs. ![]()
