  • Rsync Backup System [4]: Linux File and Directory Security Using ACLs

    As per our series on Rsync backups, we desire to use a different user from the one that owns the home directory in order to ensure they have only the permissions they need when logging in remotely. At this point whilst by default the backup user could access many things on the computer, there were…

  • Rsync Backup System [3]: Using Rsync For Full Backup

    So last time we talked about how to set up a single disk with ZFS to use compression. Having got our backup disks sorted, the next step is to work out how to use rsync to do the actual backups. rsync is written by the same people that devised samba and is a very powerful…

  • Rsync Backup System [2]: Using ZFS For Compressed Backup Disks

    So last time I talked briefly about ideas for using Rsync to do my backups. Over time this will gel into a whole lot of stuff like specific scripts and so on. Right now there will be a few different setup steps to go through. The first stage is to come up with a filesystem…

  • Rsync Backup System [1]: Introduction

    In February of last year I was looking for a new backup solution (I had used rsync to that point but found some issues with it) and tried a few different things. I have been using rdiff-backups since then (it comes as a part of Debian) but this has its issues too. At the moment…

  • Setting up a second swap partition for Linux [1]

    In my last post I waxed lyrical about the merits of the Linux file system and how it is possible to have two swap partitions. Today I am setting up just that in my computer. It has an existing SSD with 100 GB available for swap, and due to an upgrade on the other computer,…

  • Linux has the best filesystem ever 🙂

    I’ve been in the IT industry for something like 30 years (longer if I was to include the time in my secondary education) and in that time I have used a few operating systems, starting with Apple DOS 3.3, UCSD P-System, CP/M, Acorn MOS, Macintosh System 6/7, Netware, MS-DOS, Windows (since 3.1), macOS and Linux.…

  • NZ Rail Maps: Gimp optimisation with SSD works well

    A few posts back in label NZ Rail Maps, I commented on how to optimise Gimp to use the swap partition on the computer effectively. I have since been able to prove using a computer with only 8 GB of RAM that it is able to use the SSD to load much bigger images without…

  • Computing resources optimisation [2F]: Managing Disk Space Usage

    The completion of this computer upgrade project is close to finished. I do have to complete mounting the fourth computer, which is inching along at a glacial pace at the moment, and various small tasks. One of the important ones is that mainpc’s disks which have a total capacity of 1.8 TiB or 2 TB…

  • Backup software / recap

    About eight years ago I thought I was building a really special PC with a Intel DG41RQ mainboard, Celeron E3300 CPU and 2 GB of RAM. The article series started here: https://enzedtech.blogspot.com/2010/10/rebuilding-my-pc-1.html Unfortunately I outgrew that computer pretty quickly because it could only take 4 GB of RAM in total and therefore became pretty slow…

  • NFS on Linux

    When it comes to file sharing on Linux, you have two main choices. NFS is the one that is intrinsic to Unix environments, that have been carried down into Linux by convention. It has been around for a long time and is quite stable and reliable. Since the development of Samba, you also have SMB…
