SyncVM – File Level Restore


Recently I did a video illustrating virtual disk synchronization capabilities with Tintri SyncVM. Our latest 4.0 Tintri OS takes SyncVM a step further by allowing file level restores from snapshots. Currently this only works on VMware, but it is compatable with both Linux and Windows.

Let’s start by navigating to my linux demo machine from the Tintri UI via the search option

After searching for the ‘cl-linux-file’ demo machine, simply right click on the VM and select ‘Restore VM/Files’

Next, simply select the ‘Guest OS File’ radio button and then select the snapshot you wish to restore a file from on the drop down menu. I chose to uncheck the ‘Auto detach disks in 48 hours’ option because I will manually detach the snapshot when I’m finished with the restore. Then click ‘Restore’

You will see the progress in the back ground of the snapshot getting added as an additional disk. Once it reaches a 100%, you can login to the VM and mount the drive.

On my linux VM instance, I have to do a rescan to detect newly added SCSI devices. This is a very simple script (named as you can see in the illustration) that scans and then mounts the disk under a mount point I simply named ‘recover’

After running, you can see that I now have a new disk on /dev/sdb1 mounted under the ‘recover’ mount point.

Now I can simply navigate to ‘/recover/home/clucas’ and restore the file named ‘large.file’ to ‘/home/clucas’ by doing a simple copy. Then just navigate to ‘/home/clucas’ and verify the file is there.

Now that the file is recovered, I can umount the drive and then detach the snapshot from my VM back in the Tintri UI.

That’s it! Very simple to easily restore files directly within the guest OS using SyncVM file restore. The process is exactly the same on Windows, however you just use the disk manager to ‘online’ the disk that was added.

Tintri SyncVM

For most of you that know me, you are already aware I left VMware around 5 months ago to join Tintri. VMware is a great company and I’m very grateful for having the opportunity. While at VMware, I had several customers that deployed Tintri storage appliances and I never met a customer who simply didn’t rave about it. When the opportunity presented itself, I was extremely excited to take on a new journey.

Having been on board now for a little over 5 months, I simply can’t believe how simple, high performing, and feature rich our product line is. The following demo illustrates a recent feature release known as SyncVM. Not only can you synchronize an entire VM to multiple points in time, you can sync individual vDisks from other VMs.

This demonstration shows the simple process of synchronizing a production DB down to a test system. Then reverts back to the test systems previous state. Stay tuned as even more advanced SyncVM features will be announced soon!


VMworld Survival Guide For Introverts


With VMworld fast approaching, some are eager to party and catch up with Twitter friends. Wading through crowds vying for free USB keys and lighted rubber balls excites them. Others wonder how they will endure serial smalltalk. Or how they can make an appearance at an insanely loud, hot, alcohol-fueled soiree, and still execute a perfectly-timed exit.

This post will deal with the latter. You know who you are. You’re the guy or gal who loves technology, wants to be knee-deep in a tech conference. You would prefer about 12,000 less people engaging only in meaningful, passionate, technical conversations.

First things first. Realize your introversion doesn’t make you a freak who prefers being in your shell at all times. It simply means you derive your energy from within. You recharge your internal batteries alone, digesting your thoughts with few distractions. Extroverts recharge their batteries right there on the show floor. While they yell over loud music and megaphones to tell people what they had for dinner, they’re gaining energy. You are one to analyze a band’s musical prowess, while analyzing their tonal structures. Extroverts are the ones kicking you in the face crowd-surfing at the same concert.

Introverts can make gigantic tech conferences easier to digest, and condition their batteries at the same time.


1. Talk to people

The popular stereotype is that introverts don’t like people, and don’t like to carry on conversations. This couldn’t be further from the truth. Introverts love to carry on conversations with anyone who will engage on a topic we feel passionate about. Once engaged, it is hard to stop some introverts from talking. This is one reason I love attending Tech Field Day events. You’re in a pre-selected group of your peers, who are guaranteed to have passionate opinions, and want to engage on the topics you care about. Introverts generally think about a topic pretty deeply before discussing. According to Susan Cain, in the book QUIET

This “may also help explain why they’re so bored by small talk. “If you’re thinking in more complicated ways, – then talking about the weather or where you went for the holidays is not quite as interesting as talking about values or morality.””

Take advantage of vendors who are dying to tell you all about the intricacies of their products, and schedule one on one time with them. Find a few vendors you really want to learn more about. Most of the better ones will have times when you can sit for a on on one briefing, or quick “Genius Bar” type conversation with one of their engineers. I highly recommend doing this. It’ll get you engaged, and you’ll be talking to someone who is passionate, and deeply technical (most of the time).


2. Get a hotel that’s as close as possible to the conference center

Sounds like a no brainer, right? While all personality types want to minimize their walking distance, and maximize their conference time, this is especially important for the introvert. It allows you the flexibility to head back to the room, and catch your breath during the day, if you need to. When you feel your batteries running down, go ahead and skip that session you had scheduled. It’s going to be online later anyway. Head back, and wind down for an hour. Recharge, and veg out. This can make a dramatic difference in your day. If you’re stuck with all those people, and constantly shuffling from session, to hall, to crowded meals, you’ll be completely wiped before dinner.

3. Go out for meals

Yea. I know. Your company paid for a conference where meals were included. But unless you’re in Vegas, the catering is generally horrible anyway. Hit Tripadvisor, or Yelp to find close restaurants you’d like to try, and get away from the crowds for a bit. If you find other conference attendees at these places, guess what. . . They’re likely doing the same thing as you, and if you end up getting into a conversation with them, it will be engaging. They likely hate smalltalk as well, and want to share some of their complex thoughts with an equally complex thinker.

4. Don’t skip parties

Make sure you go to at least a couple parties. Most of the time, you can find fellow introverts hanging out, sipping slowly, drifting toward the door. If you do, execute a casual greeting, with all the tentativeness you’d want from them. If they do want to chat, it won’t be some asymmetrical, bombastic conversation, where you’re competing for volume. It’ll likely be on a technical topic you can appreciate, and will value. Exchange cards with that person. This is how we introverts can network without the high schmooze factor, and wasting valuable energy.

5. Don’t forget labs

If you need a break to recharge, you can always go do some labs. Nobody will bother you there, and it’s pretty quiet. Don’t stress out about missing sessions you wanted to see. Again, they’ll be available online just a few weeks after the conference.

6. General Sessions are great from hang spaces

Most of the hang spaces at the conference will be broadcasting the general sessions live. If you’re not feeling up to the crowds, you don’t need to stand in a sea of people, waiting to get a decent seat at these. Just head over to the beanbags, and watch from there.

Most of all, have fun. Don’t try to take it ALL in. Prioritize. There’s too much for even the most extroverted to experience all of VMworld.

Tom’s Picks for VMWorld 2012 – Session & Speaker Recommendations

Here is my annual “Tom’s Picks List” for VMWorld 2012. This list began several years ago as an email recommendation of some presenters to several of my strategic customers, and was passed around and is now asked about every year (so apparently it has been helpful!) I have gone through the content catalog and selected ONLY those sessions and presenters that I know personally, have presented with in other events, or come highly recommended by other colleagues I trust. There are also a few sessions this year I selected due to the topic, and the value of the topic’s subject matter for an attendee. For example, the vCenter 5.1 session (INF-VSP1353), is a session that everyone needs to attend since it is a deep dive into the latest version of the management interface into vSphere AND the presenters rock! Overall, I have listed 65 of the sessions out of 165 as of this posting that are listed in the content catalog.

Pay particular attention to the “Highly Recommended” sessions as these will likely fill up quickly, and often feature the “rock stars” and bloggers we all know and follow. Should we add any additional sessions or if someone would like to add to the list, please do so in the comments section below. Remember, YMMV on if you think my picks are accurate or worthy, so keep in mind, this is a totally personal recommendation list. I am sure there are a number of other excellent sessions and presenters who are not on the list, so if you wish to promote other sessions or speakers, please do so below.

I am a Hands On Lab Principal this year, so will be in the HOL Lab most of the time, so feel free to stop by and say hello!

See you in San Francisco and Barcelona!

Thanks! Tom
