More LVM information

Date November 29, 2008

I talked about Logical Volume Manager in my Intro to LVM in Linux.

Tonight I came across an article on backing up LAMP stacks with LVM snapshots.

I knew LVM could do it, but I wasn't aware of the particulars . Justin Ellison's article on it clarifies many off the difficulties with the process. His particular howto is geared towards LAMP (Linux, Apache, MySQL, PHP) setups, but it is by no means limited to it.

Read through his write up and let me know what you think.

One thing I am interested in seeing is how well it scales. He mentions 500MB of data, which is around 1/600th of the size I'm dealing with. I do have to wonder how quickly I could create a snapshot of that amount of data.

Anyone have more experience with this?

    Hey Matt,

    I posted a response to your comment, and this blog post. I'm still working on trackbacks on my Drupal install, so I thought I'd manually drop you a line to let you know.
