Backing up every few minutes with simplesnap

I’ve written a lot lately about ZFS, and one of its very nice features is the ability to make snapshots that are lightweight, space-efficient, and don’t hurt performance (unlike, say, LVM snapshots). ZFS also has “zfs send” and “zfs receive” commands that can send the content of the snapshot, or a delta between two snapshots, […]

Why and how to run ZFS on Linux

January 23rd, 2014, 15 Comments

I’m writing a bit about ZFS these days, and I thought I’d write a bit about why I am using it, why it might or might not be interesting for you, and what you might do about it. ZFS Features and Background ZFS is not just a filesystem in the traditional sense, though you can […]

Debian-Live Rescue image with ZFS On Linux; Ditched btrfs

January 22nd, 2014, 9 Comments

I’m a geek. I enjoy playing with different filesystems, version control systems, and, well, for that matter, radios. I have lately started to worry about the risks of silent data corruption, and as such, looked to switch my personal systems to either ZFS or btrfs, both of which offer built-in checksumming of all data and […]

Results with btrfs and zfs

December 7th, 2013, 20 Comments

The recent news that openSUSE considers btrfs safe for users prompted me to consider using it. And indeed I did. I was already familiar with zfs, so considered this a good opportunity to experiment with btrfs. btrfs makes an intriguing filesystem for all sorts of workloads. The benefits of btrfs and zfs are well-documented elsewhere. […]

Hello, ext3. Goodbye, reiser4.

October 13th, 2005, No Comments

So I’ve been trying out various filesystems over the past few months, by converting a few machines to them and using them on a daily basis. I’ve found that reiser3, JFS, and XFS are all risky and actually corrupt data on crashes. JFS also has a few weird bugs that make the kernel oops, and […]

Reiser4 Experiences

June 2nd, 2005, 6 Comments

I’ve been a long-time user of JFS, but have grown unhappy with it for various reasons. So, I decided to try out XFS. It proved no better than JFS or ReiserFS 3 with data integrity during a crash. Next step: Reiser4. I’ve been using Reiser4 for the past month or so on three different machines. […]

Trying out XFS

April 27th, 2005, 6 Comments

I’ve used most of the different filesystems in Linux. My most recent favorite has been JFS, but things like starvation with find have really been annoying me lately. To summarize, here is my experience with filesystems: ext2: very slow, moderately unreliable ext3: somewhat slow but reliable reiserfs: fast, unreliable (cross-linked data after crash issues) jfs: […]
