Take A Moment To Observe World Backup Day & Evaluate Your Storage Strategies

blog, pswblog, recording, system maintenance · 2011-03-31

As some of you may have noticed, I’m far more paranoid than most about the backing up of data. However, today as we take a moment to remember (or in some cases, mourn) the passing of World Backup Day, I’m left wondering why so few people take data backup seriously.

Let me share with you a recent story from my own experience. Just yesterday, I took delivery of a shiny new RAID after my own (albeit brief) data scare. My single remaining non-RAID online drive had hesitated to mount previously in the week due to a mismatched power supply.

Thankfully, using the correct power supply immediately solved the problem. However, it left me with a sinking feeling that illustrated the importance of proper backups. After all, even those of us who backup regularly are not without fault, and I hadn’t yet made a safety of this particular project.

Surely most of you recording professionals out there have a tried-and-true backup method in place. If not, I shared some thoughts on the subject last month in Backups: So Many Storage Options Yet Only One Chance.

For a far more in depth perspective, I would encourage you all to read the the various Technical Guidelines for Producers and Engineers set forth by The Recording Academy, which are free for members and non-members alike. Especially helpful in the archive process and the explanation of various long term storage media is the Digital Audio Workstation Guidelines for Music Production (pdf), of which there is an abbreviated Quick Reference Guide (pdf).

What I find most striking as I contemplate the concept of backing up is that some of the people I know who are the most judicious about recording data backups are rather haphazard in backing up their own personal systems, or even their most critical files.

Says Kevin Purdy of Lifehacker:

Why World Backup Day? Unfortunately, it’s necessary, as BackBlaze pointed out during Backup Awareness Month last year, with only 8 percent of those surveyed backing up their data daily. Hard drives and other storage, every single device, will fail at some point, and will never provide a fair warning about it. So find a way to put your data in two extra places: one convenient and nearby, another far away from your house or office.

Sage advice, really. I’ve said it before and I’ll say it again, there are two kinds of people – those who have experienced a hard drive failure and those who will. So on this remembrance of World Backup Day, be sure to take the opportunity and ensure that all your date is secure: both personal and professional.

A Look At iZotope RX 2 Advanced

blog, pswblog · 2011-02-28

Imagine for a moment one of the “must have” tools in your arsenal. I’d bet a large number of you out there jumped to ProTools (perfectly valid), or a favorite piece of outboard gear (I’ve been there). However, one of my “can’t live without it” tools is noise removal and spectral repair, which is why I was so thrilled to have the opportunity to check out iZotope RX 2 when it came out this past fall.

However, the reason for my excitement was far different that you may imagine. After all, yes, everyone likes to be the first to check out new gear. Rather, I was intrigued because I’d already been an avid RX Advanced user for a number of years, and my mind reeled at what they could have done to possibly improve upon the software.

Boy was I surprised!

Two new features I’ve really enjoyed in the new version are improved batch processing and the upgraded selection methods. The new method of batch processing has made an impact on my workflow because you can chain multiple modules together as well as process multiple files while using multiple CPUs which can really save some time. Also, the new selection methods which include a lasso, brush and magic wand tools have made it far easier to edit quickly and accurately. My favorite is the magic wand which can automatically select a sound and its harmonics.

As always, there are several features in RX Advanced which really make the jump to Advanced worthwhile. The new adaptive denoiser mode, which is a part of their all new denoising algorithms, is a whiz at dealing with dynamic background noise. Additionally, azimuth alignment, which is a component of the new channel and phase operations feature, does a great job of correcting misaligned tape heads if you find yourself regularly restoring tape.

There are so many great additions to this update that I was left wondering how I’d ever worked without them, like session support, third party plug-in support, and if you’re using RX 2 Advanced for forensic work then the ability to export your work history as an XML file will come as a welcome addition.


My first true test of iZotope RX 2 Advanced came while hurriedly editing a project for my wife. A middle school teacher, she’d recorded her students reading aloud for a podcast. Knowing it was just a school project we opted to go the quick and dirty route for recording, an iPhone. While the source was captured just fine, I’d underestimated the level of background noise in the 1920’s building. Against a rather tight deadline, I was able to run several hour long files through RX 2 Advanced, using the new adaptive denoiser mode, some moderate EQ, and the occasional spectral repair, which all came out sounding far better than I had expected given their original state.

In speaking with a colleague of mine after cleaning up these recording I said “I’ve got to write about this and tell everyone about this great software!”, to which he replied, “No, I don’t want anyone to know. Its my secret!” That seems to be a common sentiment among iZotope RX users, as those who use it regularly are constantly pleased and amazed by its power, but always hopeful they can keep the app as their own secret silver bullet of post production.

Give it a shot; I’m certain you’ll see what I mean.

backups: so many storage options yet only one chance

blog, pswfeature · 2011-02-10

It’s been said by IT professionals around the world that there are two kinds of people – those who have experienced a hard drive failure and those who will. Unfortunately, we surely all know at least one person who’s lost data in a catastrophic failure.

Personally, I’m a believer in the 3-2-1 backup strategy which has been expanded upon greatly by Richard Anderson in his article aimed at digital photographers.

Put simply, for every file you intend to preserve you must have three copies of that file, on two different forms of media, at least 1 of which is stored (securely) off-site. This protects the data (and your reputation) not just against hard drive crashes, but other disasters as well.

So, this begs the question, how are you backing up you data? If you’re reading this article, my guess is that you may already be wondering if you’re doing everything you can to protect your information. Don’t worry, I wont judge. If we’re going to be honest, I haven’t followed this backup strategy 100% until just recently. After all, it only takes just one near miss…

I received a rather frantic email recently from a client on this very subject. It was he who’d had this near miss when one of his hard drives failed; he nearly lost years of work. Unfortunately, a few files were corrupted on the drive and he wanted to know if I still had them.

Sure! Granted, the project was from 2004, but my data retention policies are such that I keep everything. More on that another time…

Anyways, I fired up one of my many offline storage drives, uploaded the files to FTP, and washed my hands of the task. However, days later, the age of my backup drives began to weigh on my conscience. After all, the data had been sitting there for quite some time, and what if the failure had occurred not to a client but to me? Then the data wouldn’t have been salvageable!

I decided to take a long, hard look at my data backup process. To clarify, this isn’t to be mistaken for how I backup my primary system drives, though I’m certain some of these changes will trickle down to that as well. Rather, this is strictly how I backup my non-system drives which contain all my online and offline sessions (You are recording to a non-system drive, right?). One of these days I’ll talk about system drive backups if anyone is really all that interested.

The Process
Essentially, I like to think through backups as a series of options. To achieve two local and one remote backup there are any number of solutions we can use. It’s all about weighing the pros and cons of each with regard to your individual needs. So, we’ll take a look at the various technologies available for backups. However, one thing to keep in mind when you’re actually shopping for drives, no matter the technology employed, is the platters employed within. The life expectancy of a drive is related to its MTBF or mean time before failure. However, the MTBF is just that – a mean – which represents the average failure rate for the entire population of drives tested.

OWC Mercury Elite Classic

This value is generally high, but it does tell you something about the likelihood that your drive will fail. There is no way to tell exactly how long a drive will last but if you’re shopping for drives taking a look at the enclosed platters’ MTBF data is a great idea. Now, on to the options!

Single Drives
A single hard drive is a great storage solution for its capacity (which is constantly expanding by the day). That is of course until it fails which is why it’s important to have 2 copies of your data backed up. If you only have a small studio, two single drives are not a bad backup at all.

However, even if you use another backup method, singular hard drives make a wonderful working or “online” drive. If you’re the type to build your own drive, I can’t recommend highly enough the Hitachi Ultrastar series of discs, but any enterprise-class disc is a safe bet. My personal choices for pre-made enclosures are the Other World Computing Mercury and Mercury Elite’s.

Computer Attached Multi-Disc Enclosures
Once you’ve outgrown a single disc solution, you know you’ve accumulated a lot of data! You could seemingly add another single disc to your workflow which is what I’ve been doing up until now. My tipping point was 6 single drives which made finding files rather convoluted.

A much better alternative is stepping up to a multi-disc enclosure. These often have the added benefit of expandability along with the data hoarders best friend, RAID technology. An acronym for Redundant Array of Independent Disks, a RAID array is a serious step up from a single platter.

Wiebtech RTX400-QR

It’s a technology that provides increased storage functions and reliability through redundancy which is achieved by combining multiple disk components into a single cohesive unit, where data is distributed across the drives in one of several ways called “RAID levels”.

There are numerous great (albeit pricy) units on the market today, some of my favorites being the Wiebtech RTX400-QR (at right) and any of the numerous options from Other World Computing. Having a RAID array is a perfect way to achieve two local copies of data, especially due to RAID technology’s ability to rebuild the array after a failure. You’ll notice I called these devices “computer attached.” So, what if you wanted a massive RAID backup bout wanted to place it on your network? Enter the NAS!

Network Attached Storage
If your studio workflow contains a multitude of computers and you want to backup all your projects to a singular location, a NAS is quite a solution. Depending on its configuration, it can function as either a RAID or (sorry, it’s acronym time again) as a large singular drive which is called JBOD or “Just a Bunch of Drives.”

QNAP TS-439 Pro II+ Turbo NAS

Depending upon your needs and the configuration of the NAS, projects can potentially be retrieved remotely with the proper credentials. My favorite candidate in this category has recently become the line by Qnap, one which I’m slated to deploy for a client in the coming month.

Welcome To The Cloud
When it comes to off-site backups, that’s when many people begin to falter. After all, it’s one thing to purchase a whiz-bang RAID enclosure and back everything up, but when you start talking about finding another place for your data to live which isn’t in your studio, that’s when things get a bit tricky.

Unless you’re going to constantly image your backup and rotate it offsite (I’ve received this suggestion by corporate IT folk), it’s likely you’re going to be looking at some form of storage “in the cloud“. Cloud storage has become extremely popular in the pat year although many will tell you it comes with risks. They’re correct, although it’s worth remembering that “cloud storage” is just another way of saying your information is stored in a large data center, some of which have serious backup plans of their own. They’re worthy of consideration.

Iron Mountain Data Bunker

One of my favorite options for online storage is Dropbox, which offers a modest amount of free space and paid plan beyond that. Another great cloud storage option is Jungle Disk. While I’ve never tried it, the features are quite solid, especially given the price. If you’re looking for a secure cloud server but don’t need something quite within the range of military grade, it’s worth considering.

While Dropbox and Jungle Disk are worthy backup options, what about the truly paranoid among us (myself included) when it comes to remote storage? Thankfully, there’s always at least one option out there which goes the extra mile; for critical backups I’m excited about the availability of Iron Mountain’s subterranean data bunker.

While seemingly extreme, if your data is mission critical (and you know it is), there’s a great deal of comfort in knowing your backups are safe offsite in a highly secure underground facility, and mirrored to a second data center for full fail-over redundancy while your data remains encrypted in transport and storage.

The Verdict
You may be wondering, having heard these options, exact what solution I settled upon. It was quite a struggle, but I decided the best option for me was a computer attached RAID coupled with a single disc for online work, and a third copy of my data mirrored in Iron Mountain. Why, you might ask? I decided that having a physically attached RAID was the best option as i only mix on one or tow computers.

Also, I feel the singular drive is necessary as I don’t want to run the risk of corrupting my backup by working from it on a daily basis. I’ll admit that Iron Mountain is a bit of a splurge when it comes to data archival, however, I decided it’s hard to put a price on knowing that there’s always another copy of everything I need, fully RAID’ed and geographically separated, so I know it’s safe. Basically, if I lose something, it means there’s been a catastrophic event so terrible that the data has probably become irrelevant. And frankly, I’m ok with those odds.

I’m certain that someone out there has noticed I skipped over a few backup options. For instance, DVD backup. Personally, I don’t find it convenient to burn a backup of every session twice, and then make amendments to that backup if I work on it again. Plus, a suitable offsite storage location is still required. I know safety deposit boxes are popular, but while this backup methodology is perfectly valid and reliable for smaller quantities of data, I don’t feel it’s worthwhile to entertain when dealing in terabytes.

No matter the route, whether it’s a few single hard drives coupled with Dropbox or an in-studio server farm which makes my storage upgrade look minuscule at best, I hope you’ve found these options insightful. After all, few experiences are more painful than data loss, and I hope when you’re greeted with the heart-wrenching clicking of an armature that you know everything is safe and sound on another drive.

Happy archiving!

firewire device hierarchy: does it really matter?

blog, pswblog · 2010-01-20

FireWire; it just sounds fast, doesn’t it? At the very least, it certainly sounds faster than USB. Perhaps that was Apple’s intention when they sat down with Sony, Texas Instruments, and many others to create an amazingly accessible data transfer specification that conjured up the image of reliability ease of use within the minds of users. However, if FireWire has one flaw, it’s that it’s too easy to use. What do I mean? Let’s compare the connectors for USB and FireWire. While USB has an A and a B side, FireWire simply has a side. Sure, FireWire has 2 different specifications with 2 distinctly different connectors, however, each has only one connector style.

Back to the point…
If FireWire has one flaw, it’s that it’s too easy to use, because there’s often a great deal of confusion as to in what hierarchical order devices get connected, as any device can seemingly be plugged into another. In reading audio forums and message boards over the past 2 weeks, I have found nearly two-dozen post asking which comes first, the audio interface or the drive. Why? More often than not, engineers are concerned about possible audio drop outs and decreased drive performance, which aren’t completely unreasonable concerns.

Why is this an issue?
Can’t devices be plugged in however I want? Well, that depends, really. Some device manufacturers like MOTU and Apogee make no mention of a device hierarchy preference. Others, such as RME, have seen notes in their forum that when using on Mac’s containing the LSI/Agere FireWire chip-set their audio devices only work when a FireWire drive is placed between the audio interface and the computer. Others still, such as industry leader Digidesign, note the following. Personally, the fact that this is spelled out so plainly just makes me feel it’s a necessity.

From the 003 Getting Started Manual
Connect FireWire hard drives directly to a FireWire port on your computer.

The FireWire ports on 003 and 003 Rack do not pass audio data when they are powered off. If you daisy-chain FireWire devices from your computer, it is best to connect FireWire hard drives directly to your computer and not to 003 or 003 Rack. This will prevent hard drive errors and data loss in case 003 or 003 Rack is powered off.

If your computer has only one FireWire port, connect the FireWire hard drive directly to your computer and then connect 003 or 003 Rack to an available FireWire port on the drive.

Ok, so this is just for ProTools users and the paranoid?
No, not really… Personally, I think it’s good to adopt a set methodology of doing something even as mundane as hooking up a hard drive and stick to it, which is why I practice this habit. Also, for the other end of paranoid who are worried about audio drop outs, sticking to a stable setup will allow you to trouble shoot the root cause of those issue as it’s probably not FireWire bandwidth.

Why?
Well, a number of reasons. If you read the basics of the IEEE 1394 spec (it’s a dry read) or consult the 1394 Trade Association you’ll find that FireWire can connect up to 62 peripherals. Now, obviously you’re not going to do something foolish like that in a recording session. In fact, if you read the Digidesign ProTools 8.0 LE System Requirements, you’ll see that Digidesign recommends no more than 4 daisy chained FireWire drives, which are not to be mixed of FireWire 400 and 800. However, even at 4 drives, that gives you quite a bit of leeway before you should start to have any problems.

So, I should just trust you?
Well, ultimately that’s you’re decision, isn’t it? Personally I think this is sound policy and given what I’ve found I’m not the only one. However, if you’re a Mac or PC user with multiple free FireWire ports or a DAW user that uses a USB Hard Drive (shame on you!), then this really is of little concern to you. Either way, if you’re ever in a situation where the hierarchy of FireWire devices is at issue, I’d recommend placing hard drives in line before audio interfaces.

What’s your take on FireWire connectivity? Do you have a set device hookup methodology? Try it a different way each time? Whatever your thoughts or experiences, let us know in the comments below!

microphone data resources

blog, pswblog · 2009-12-11

It’s no secret an engineer’s knowledge of his tools is a source of great power. Anytime I’m preparing for a recording session or live sound gig, the first thing I set upon once I determine the makeup of the ensemble and the equipment at my disposal is to determine how best to utilize the available microphones. One of the best tools any engineer has in this task are manufacturer specifications. However, almost all microphone manufacturer websites are laden with Flash applets that are difficult to navigate and which can make it impossible to find the correct information. Thankfully, websites exist that provide an interface far more convenient than most manufacturer websites, and provide data for almost every modern microphone in and out of production.

Microphone Data

Microphone Data – microphone-data.com

From Rycote, the makers of wonderful windshields, comes Microphone Data (free login required). They’ve compiled an extremely comprehensive database of microphone data which can be easily compared across manufactures and microphone styles. When it comes to planning for a gig, this is always my first stop.

“The Microphone Data website is the successor to the original Microphone Data Book – the truly comprehensive free online database & guide to microphones in professional use today. The Microphone Data site deals in facts, not opinions, with pictures, response curves and technical data from the manufacturers themselves for every currently listed microphone (and even a few that aren’t)”

from microphone-data.com

Recording Hacks

Recording Hacks – http://recordinghacks.com/microphones

Recording Hacks, the online magazine about recording gear and techniques, also maintains a wonderful database of current and out of production microphones. As well, they also maintain the official TapeOp Microphone Review Archive which is a fantastic source of microphone information.

Personally, I tend to “re-discover” these microphone data resources about once every six months, typically after becoming horribly frustrated that I can’t find the specifications I’m looking for, or after a futile attempt to compare specifications from different manufacturers. Whether you share my frustrations or you have reasons of your own, I hope that you’ll find value in these resources.

What’s your take on the currently available microphone resources? Do you swear by the Rycote database? Would never dream of using data that didn’t come right off the manufacturer’s server? Whatever your thoughts of experiences, let us know in the comments below!

don’t come unglued, bake a tape!

blog, pswblog · 2009-12-02

In late 2008 I was called out by a friend to repair a Studer tape deck; an A827, which I had never used before. While I was very fortunate that the studio owned both the original alignment tape and tentelometer, the original (rather aged and unused) tape shed like crazy because of its storage conditions, and our inability to bake the tape before use.

Baking has gotten myself and many a colleague out of a sticky (ha ha) situation. However, I’ve run across my fair share of engineers who either don’t know what baking is, or who don’t have a tried and true method. So, I thought I’d pass along this great article by Eddie Ciletti, If I Knew You Were Coming I’d Have Baked A Tape! It’s a remarkably thorough read, and full of information about tape baking for both novices and pro’s. It has been cited as the definitive source of information in all manner of post across the TapeOp Message Board (TOMB), GearSlutz, and even an Electronic Musician feature. While you’re there, check out some of his other articles on tape machine maintenance, which have all appeared in print, and include some great advice. All in all, what a great resource!
