Secure and flexible backup server with dm-crypt and btrfs

In our previous article we described an idea setup for a modern server with btrfs for flexibility and redundancy. In this article we describe another kind of setup that is ideal only for a backup server. For a backup server redundancy and high availability are not important, but instead maximal disk space capacity and the […]

The perfect Btrfs setup for a server

Btrfs is probably the most modern filesystem of all widely used filesystems on Linux. In this article we explain how to use Btrfs as the only filesystem on a server machine, and how that enables some sweet capabilities, like very resilient RAID-1, flexible adding or replacing of disk drives, using snapshots for quick backups and […]

Using RAID with btrfs and recovering from broken disks

Btrfs (pronounced Better FS) is a relatively new filesystem that operates on the copy-on-write principle (abbreviated COW, which stems a more friendly pronunciation for btrfs: Butter FS). Btrfs includes a lot of interesting functionality and replaces traditional Linux disk and filesystem tools like LVM (volume manager, disk snapshots) and mdadm (software RAID). In RAID usage btrfs is much more flexible […]
