vRetreat: Cohesity Overview

At the recent vRetreat at Silverstone, I experienced three technical presentations / Q&A sessions from the event sponsors. One of these, Cohesity, I was charged with writing a little more about. Up until that point, my experience and knowledge of Cohesity’s solutions was very limited as I’ve had my head buried in several large projects over the recent months. Ezat Dayeh‘s presentation at the vRetreat was therefore a great introduction for me to Cohesity’s mission and value proposition. Cohesity was founded in 2013 by Mohit Aron, former co-founder of Nutanix and a Google File System lead developer. With this DNA, it’s no real surprise that Cohesity’s solutions have a storage focus. The difference with Cohesity is that its focus is not around primary storage (production virtual machines, databases etc), but secondary storage (file shares, backups, archives etc). Their mission is to redefine […]

Removing the whitespace from text files in Sublime

I like Sublime Text, it’s my favourite text editor. Handily available for OSX and Windows. What’s annoying though is when you get given or open a text file that has loads of whitespace at the end of the lines. Aside from messing with my compulsive sense of order, there are cases when extra whitespace can cause problems for some applications. Just in case, there’s a handy configuration option that can strip out trailing whitespace when a file is saved. Here’s how to set it up… Open Sublime’s preferences – in OSX this is done by “cmd + ,” Add the setting “trim_trailing_white_space_on_save” and set it to “true” Save the preferences file Bingo! Whitespace will be trimmed when files are saved in future. Just for clarity, the full setting in a fresh config file looks like this:

Some other TimeMachine exclusions

In my other post on the topic I excluded my local Mail app files from my TimeMachine backups because they were tripping over McAfee AntiVirus. I thought that it might be sensible to add a few other exclusions to trim down the total amount backed up and reduce the impact of frequent TM backups on my laptop. As you can see, my total backup size is about 380Gb. Included in that are a fair few transient / temporary files that aren’t needed as well as some files that are backed up elsewhere anyway plus a handful of things that maybe I don’t need or want to back up. Caches Really, you want to keep them? I thought not. They include the browser caches for Safari and Firefox amongst other things. Click the “+” button. In the finder window that’s displayed, […]

Infected email breaking OSX TimeMachine backups

Having been away from home a lot recently, it had been a while since my laptop had been backed up by TimeMachine. After a few attempts though it got a bit annoying as McAfee kept interrupting the process. The problem seemed to be that the backups contained infected emails: McAfee was blocking TM from writing infected emails to the backup drive. As it turns out, I recalled fixing this once before (although I never blogged about it). So how could it have come unpicked? Looking at my TM backup exclusions, the exclusion that I added was still in place: But my whole mail folder should be more than 8KB!… Then it clicked. I hadn’t done a TM backup since updating to OSX El Capitan. After clicking the “+” button to add a new rule, I navigated to my mail folder. […]

Unitrends Free – Review: Part 2

In Part 1 of this review, I walked through the deployment and initial configuration of the Unitrends Free backup appliance. I’m now going to touch briefly on some of the other features of the product before summarising my thoughts. Recovery There’s no point taking backups if they don’t work, right? Well there are a few options available here. The first of them is a file level recovery. This mounts a VM’s backed up disks as file shares on the backup appliance. To test it, I created a couple of test VMs to backup and selected to restore from one.   A file level recovery “job” is started and a share is created using the backup job number.     It’s pretty easy to browse to the share and the required files could be recovered from there. Another restore option is an Instant Recovery. […]
