Network Attached Storage for Automated Backups

Prevent Lost Data

Many DC area residents have been contacting me lately with hard drive failures and lost data. Data can sometimes be recovered using software such as SpinRite. But it’s easy and relatively inexpensive to be proactive and backup your data. The best backups are automated, using free software such as SyncBack for Windows or the built-in Time Machine for Macs.

Backup Locally

Backups can be sent to a local USB flash drive or local USB hard drive. The Western Digital My Passport Essential 500 GB costs about $107. These use laptop hard drives which have the advantage of being able to run only on USB power. Larger 3.5 inch external drives can hold more data but require an additional power supply.

Network Backups

If you have more than one computer, a better solution can be to backup to a network attached storage (NAS) drive. This connects by ethernet to your router allowing you to connect to it through your home network.

Here are a few solutions:

Apple Time Capsule

If you are a Mac user and you want the simplest solution, you’ll have to pay a lot more for the Apple Time Capsule. Apple just upgraded their large capacity Time Capsule to 2GB for $499. The Time Capsule is both a NAS and a wireless router, so it simplifies your setup. However it is only a solution for automated Mac backups that use Apple’s included Time Machine software.

Buffalo Linkstation

Buffalo Technology Linkstation Pro LS-XH1.0TL 1 TB is a great NAS that costs about $215 currently. It is fast and works as a Time Machine drive for Macs just like Apple’s Time Capsule above, though you’ll have to login to the Buffalo to set up that capability. You pay a bit more for the Buffalo’s speed than the below Iomega. If you are only using the NAS for automated backups, speed is not particularly important. Speed is helpful if you are also using the NAS as a network shared drive. The other advantage of the Buffalo and the Apple Time Capsule is that they are near silent. You have to put your ear right up to them to hear the small fan.

Iomega Home Media Server

Iomega Home Media Server 34337 1TB is a good media server, which is cheaper ($148) but a bit slower than the Buffalo. It is not loud at all, but the fan is noticeable. It includes software for automatically backing up 5 PCs. You can also backup to it with a Mac by using free software such as SuperDuper.

NAS Reviews

SmallNetBuilder.com is a great site for NAS reviews. They also have charts such as this one which show you the speed versus price. I circled the Buffalo and Iomaga drives mentioned above illustrating the Buffalo’s excellent performance.

Multi-drive NAS

For larger businesses or those who want an extra backup of their backup drive, consider a NAS that consists of multiple drives. This could be a RAID (Redundant Array of Independent Disks) box such as a Netgear ReadyNAS. Or it could be a Drobo and Droboshare. These solutions are more expensive and often slower than single drive solutions. But they ensure that your data will safe if one of their hard drives crashes.

Backup Your Data

In the world of computer support, nothing is worse than seeing someone lose family pictures or days of important accounting data. Given the low cost of storage, there is no excuse for avoiding backups. Automated solutions are a simple way to keep your digital data safe.

Upgrade Hard Drive with Free Tools from EASEUS

We recently helped someone in Adams Morgan upgrade their laptop to a larger hard drive. It was for an old Dell laptop running Windows XP (32-bit) that had an ATA (IDE) drive instead of one of the newer SATA drives.EASEUS

Here are the steps to upgrade a hard drive. The EASEUS software is free for personal use.

1. Buy a new drive. Currently the largest ATA drvies are 320GB and SATA drives are 500GB. 750GB SATA drives are anticipated in 2009 and 1TB drives are expected in 2010. We typically buy hard drives from Newegg.com.

2. Buy a USB laptop hard drive adapter or USB drive enclosure for the new drive. Again, try Newegg.com.

3. We recommend first running the Windows Disk Defragmenter so that your new drive will start out with the files well organized. It is located at Start – All Programs – Accessories – System Tools – Disk Defragmenter. In order to run Disk Defragmenter, you need at least 15% free space. This might mean that you need to run Disk Cleanup or back up and temporarily remove some of your larger files such as photos.

EASEUS Disk Copy4. Download the free EASEUS Disk Copy. This will provide you with a .iso file that you can burn to CD as a disk image.

5. While the computer is off, connect the new drive to the computer via USB adapter or USB enclosure. Start the computer with the EASEUS Disk Copy CD created above. You might have to go into the BIOS to prioritize the CD drive to be bootable. This will boot into EASEUS Disk Copy and allow you to copy the entire old drive (also known as cloning) to the new drive connected via USB. In our tests, EASEUS Disk Copy was able to move 55GB of data in about 35 minutes. We found EASEUS Disk Copy to be one of the fastest bit-for-bit copying systems. For comparison, we tested Norton Ghost which copied 55GB in over 3 hours.

6. Remove the old drive and replace with the new drive. Boot up the computer.

7. Download and run the free EASEUS Partion Master 3.5 Home Edition. This is needed because EASEUS Disk Copy only copies (makes a clone of) the drive as it is sized. Use the Partition Manager to expand the partition to use the entire drive.

Some initial Palm Pre Reviews

The Palm Pre has just been released and most of these reviews are from review units.  This means some of the issues may be resolved with OS updates.  Here are some of top reviewers initial problems with the Pre.

Phonescoop.com

When the Pre is attached to a PC to sync media, it cannot make or receive calls or text messages!!! What the what?!? Palm doesn’t provide an explanation, but that’s just ridiculous.

The Wall Street Journal

The Pre’s biggest disadvantage is its app store, the App Catalog. At launch, it has only about a dozen apps, compared with over 40,000 for the iPhone, and thousands each for the G1 and the modern BlackBerry models.

During my testing, one of my downloads from the App Catalog caused my Pre to crash disastrously — all my email, contacts and other data were wiped out, and the phone was unable to connect to the Sprint network or Wi-Fi.

USA Today

I encountered occasional sluggishness and bugs. At one point, the clock was out of whack. At another, I had to shut down the Pre because the onscreen icons kept dancing around.

Gizmodo

The first thing you’ll notice as you slide open the Pre is the absurdly sharp ridge digging against your palm. Nowhere—not on the iPhone, the G1, the G2 or any of HTC’s other smartphones—has a phone been so threatening to the integrity of my skin.

Opening multiple apps at once really does slow down the phone enough to be noticeable. In fact, if you’re doing something particularly intensive, you’ll actually notice your music stutter, which we’ve never experienced once on the iPhone. Ever.

Engadget

Besides the standard issues we had with the construction of the phone, we did spot another peculiar problem we hope is just a one-in-a-million fluke with the test device we were given: it physically broke… There is a small flap that covers the MicroUSB port, and while attempting to get the thing open, a thin piece of plastic which runs along the bottom of the casing just snapped.

The good news for Palm is that reviewers still liked the Palm Pre, at least in theory.  But their biggest gripes are with the physical device.  There were lots of complaints about the keyboard as well as battery life.  Since Palm is a fragile company, it could be difficult for this device to save them.  On the other hand, there are plenty of iPhone haters out there and due to the lack of current competition, I’d expect all of them to be interested in the Pre.  If Palm can survive and resolve some of the physical flaws of the Pre, a follow-up version could be much more compelling.

Ooma VoIP Phone System Review

Ooma Core VoIP Phone SystemThere have been many technologies I’ve been skeptical of, none more so than Ooma, a VoIP phone service. If you don’t know what that means, essentially it is a way to make phone calls through your pre-existing internet connection as opposed to using a normal phone line. Ooma has several big selling points, all of them true.

  • You don’t need a running computer to use it.
  • You can hook up all your old normal phones to it.
  • Landline call quality.
  • Free US long distance. International calling available for pennies per minute.
  • Typical services like Caller-ID, call-waiting and voicemail are included.
  • And last but not least, the service is free.  There is also $100/year premier service that adds even more features like an extra phone line, extra phone number and the ability to check your voicemail online.

So what’s the catch?  Well, there are a few.

Purchase Hardware

You do have to purchase the Ooma Core VoIP Phone System.  That link goes to amazon which is the cheapest place to buy it from.  List price is $249.99 but amazon usually has it for much cheaper.

Installation

Because Ooma is an internet service, it isn’t for everyone.  You need to have at least some basic understanding of computer technology.  If you don’t know what an ethernet cable or router are, this product isn’t for you.

The first step is to actually activate your Ooma service which you can do through ooma.com.  It is a very short and simple process where you enter a few numbers on the bottom of the Ooma Hub and then select your primary phone number and password.  After that, you’re ready to install the devices.  You also have the option to port over your current home phone number but that costs $40 and takes more time.

When you purchase the Ooma Core VoIP System, you receive an Ooma Hub and an Ooma Scout.  The hub is what connects into your network like a computer and is what does all the work.  The scout is hooked up anywhere you want additional phone lines.  1 scout is included but you can purchase extra scouts as you need them.  If you have a cordless base station phone with extra handsets, that is ideal because only the base station needs to be near the hub or scout.  I highly recommend the Panasonic Dect 6.0 – 3 Handset System.

Ooma Hub backOoma recommends you install the Ooma Hub between your router and DSL/Cable Modem but I do not because it adds unnecessary complication to your network.  Instead, treat the hub like you would any computer and plug its “modem” port directly into your network router/switch.  As a result, ignore the “home” port.  You can plug a phone into the “phone” port and the “wall” port should plug into your home phone line system.  That is how the Ooma Scout communicates with the Ooma Hub, over your pre-existing phone wiring.  At at any phone jack, plug in the Ooma Scout which just has a “wall” and “phone” connection to hook up another phone.

Packet Prioritization

One reason Ooma wants to hook up right after your DSL/Cable Modem is because it can then prioritize the Ooma packets to be high priority.  Without that, heavy internet usage could cause your voice quality to degrade.  Instead, you can setup Quality of Service (QoS) in most modern routers.  In Linksys routers for example, look under “Applications & Gaming” and then “QoS”.  You will want to add “High” priority to the MAC address of your Ooma Hub.  The MAC address is located on the bottom of the hub.   As long as you’ve done QoS for the Ooma Hub or installed the hub in front of your router, your packet prioritization should work perfectly.

Quality of Service

Call Quality

I was most skeptical about the claimed landline call quality.  I’ve used many other VoIP services, the most popular of which is Skype.  Skype call quality does not compare to a landline in my opinion.  It is acceptable but not awesome.  Vonage is considered to be high quality but is very expensive for VoIP.  Ooma is free after you purchase the initial hardware.  The resultant call quality really did shock me.  It sounds terrific but you don’t have to believe me.  Check out all of these Amazon Reviews.

While I had great call quality, it doesn’t mean you will.  Because Ooma goes through your internet connection, the call quality is completely dependent on the quality of your internet.  Typically the upload speed is what is the biggest bottleneck.  Ooma recommends you have at least 256Kbps.  I have a 768Kbps plan and get about 670Kbps on average.  It appears Ooma tends to use about 100Kbps so it makes sense they recommend more so you have room to make calls while still using your internet for other things.

I attempted to see if I could push my internet connection to its limits and see how Ooma would react.  I did 2 Ooma voice calls (via the premier plan’s 2nd line), 1 iChat video, while also downloading an HD movie and uploading large files to servers.  Ooma call quality did not degrade at all.  In part, this is because the Ooma data packets were higher priority than all the others.  So you can push your internet usage as much as you can and the Ooma calls should not degrade.

Faxing over VoIP is notoriously difficult due the way the compression virtually destroys the fax data stream.  Impressively, faxing over Ooma does seem to work.  They don’t guarantee it will work but it did work in my tests. You have to dial *99 from your fax machine before the number.  It is unclear exactly what this *99 does but I assume it tells Ooma to prepare for a fax and it can then optimize for that.  They imply that the shorter the number of pages are you sending, the better your chances of success.

Blacklists

One really neat feature I feel I have to mention is the blacklists.  This is only a premier feature but it is really cool.  Lets say you get a call from a telemarketer.  Feel free to hang up on them or taunt them as you wish but afterwards, login to ooma.com and blacklist that number.  You don’t even have to enter it, you just select it from your call history.  Then that number can never call you again.  Instead, they will hear a very pleasant voice telling them they are blocked.  In addition to the personal blacklist you can maintain, there is also a community blacklist.  If enough other Ooma users mark a number as blacklisted, then it will eventually be blocked for everyone using the community blacklist even if they’ve never called you.  This is actually how spam blockers work so I consider it a phone spam blocker.  The last remaining unwanted call I get is from telemarketers who block their number.  You can setup Ooma to not ring if no caller-ID information is available.  In all of these blocking solutions, you have the choice to simply block them or send them directly to voicemail.

The Real Cost

If you used a VoIP service that required your computer to be on 24/7, you’ve got to pay for the high power usage of your computer.  The Ooma Hub uses about 10 watts so it will add very little to your electric bill.  If you want the premier service that offers some very attractive extra features, it is $12.99/month or $99.99/year.  The initial hardware purchase is over $200 but hopefully the hardware will lasts for years.  It is essentially like a router and routers usually last for years.  If your hub broke, you’d have to contact Ooma to get it replaced and that cost is unclear.  For me, having the hub and the scout was all I need but some people might need additional Ooma Scouts and those are not that cheap at $69.99 each.  There is no charge for the normal Ooma service plan.  They do technically have a 3,000 minutes/month limit but claim they have never actually shut anyone off due to that.  They say they only have an official limit to prevent commercial use.

The Company

So the calls are great, the service is free, but will this company survive?  That’s perhaps the biggest concern.  Ooma, Inc. is a privately held company so not much is known about their profitability.  The risk is that you buy a $200+ hub that becomes worthless when the company goes under.  On the other hand, the company has shown signs that they may have an ok future.  Currently they only make money off of the hardware sales and premier plan.  They have also said they are looking into business solutions such as an Ooma service with 8 phone lines.  This could be very lucrative for Ooma and allow them to continue to offer their free service indefinitely.

Conclusion

If you are willing to take on the risk of dealing with a company you don’t know much about, the payoff could be big in phone bill savings.  I didn’t believe all the amazon positive reviews but in the end, I have to agree with them.  The service has worked great.  I like some of the extra premier features like the blacklist and extra phone line and phone number.  I have a local phone number but also a number near relatives across the country so that they can call me without paying long distance.  You can’t do that with a real phone line, nor the blacklists.

Ooma is relatively easy to hookup and use.  The extra features and nice website make me highly recommend it.

Cheap WiFi Antenna Boost

We recently setup a wireless antenna and bridge for a customer in Occoquan, Virginia that needed WiFi to be transmitted across a large building and through floors. While the setup worked, the signal was poor. This caused lows speeds and even occasional lost connections. Therefore we setup a cheap directional antenna to point the signal directly where it needed to go. This fixed the problem by increasing the signal strength by about 40%.

How To Build The Antenna

Go to freeantennas.com’s Ez-12 page to download the image at the bottom of the page. Then resize the image as needed, print it, use business-card strength paper, glue on the aluminum foil, and put it together. Patrick Norton explains this simple project on his old DL.tv show.
