Backing up your data is a good first start, but what if you want to be able to easily restore the entire operating system just as you had it, with all the installed applications and exact same configurations? There are solutions available for both Mac and PC:

For Windows XP (or Vista, etc.), there is a free option and a paid option:

The free option for hard drive cloning for Windows is DriveImage XML.

The paid options are either Acronis True Image 11 or Symantc’s Ghost: I prefer the Acronissolution personally, and you can download a free trial here.

For Mac OS X, SuperDuper! is an excellent program. If you’re running Leopard (OS 10.5.x), you also have the option of using Time Machine (which is built into the operating system), but SuperDuper! is still worth the small investment. With SuperDuper! you can make a bootable image of a hard drive to restore the entire operating system.

Here are some examples that illustrate this continuum:

“How To Build a $10 Wifi super antenna”

“How To Do basic pen tricks”

“How To Watch any video on Youtube in HD” (simply add “&fmt-18″ to the end of the URI in YouTube.com, or download the Better YouTube Firefox Add-on.)

“How To Tear a phonebook in half with your bare hands”

Shamefully I find myself gravitating toward both extremes: today I learned both “How To Crack an apple in half with your bare hands” and “How To Change a bicycle brake cable”.

If you’re looking to learn new skills as well as waste precious moments of your finite time here on Earth, this is the site for you!

This is useful if you have any old hard drives lying around, or if you have a hard drive that won’t boot and you just want to see if you can get any data off of it from another machine. It can be used for data transfer, backup, or imaging (cloning).

Connectivity is easy since any computer will have a USB port, but if you have an eSATA card you will get much faster transfer speeds.

Ordering to the US cost me an extra $25 in shipping for a total of $79.00, but I think it’s worth it considering it can be very handy in a number of situations.

If you really don’t need the eSATA port, they have another version with extra USB ports to also act as a 4-port USB hub.

What if you could store all your website passwords in an online, encrypted password vault, and access them from ANY machine?

You can have all this — and more — for only $19.99! I’m kidding: it’s actually all free. All you need is Firefox, a free Google account, and the Google Browser Sync Firefox Add-on.

Google Browser Sync gives you the option to sync your “Saved Passwords” in Firefox up to Google’s servers (where they are encrypted). You can also choose to sync your Firefox Bookmarks, Cookies, Browser History, and even Tabs and Windows.

Even if you’re using only one machine, it’s nice to know you have a backup of this information online.

If you use more than one machine, you can login to Google Browser Sync with your Google account (of course both machines need Firefox with the Google Browser Sync Add-on). (NOTE: if you have Gmail, then you already have a free Google account).

These also works between a Mac and Windows machine, since Firefox Add-ons are cross-platform.

Here’s an example: let’s say you use Firefox at home on your Mac, and you also use Firefox at work on a PC. If you save a password in Firefox on your Mac, it will sync up to Google’s servers, and when you go to work and use Firefox on your PC, that password will be available. If you also choose to sync Bookmarks, Cookies, Browser History, and Tabs and Windows, you will have the same Firefox experience on both computers.

This is especially helpful if at work you use Internet Explorer for official business and Firefox for, uhh, “other” purposes (i.e., personal use only during approved lunch breaks, and even then only if you’ve completed all your TPS reports).

One note of caution if you choose to sync bookmarks between machines: each machine added will synchronize all your bookmarks, so they will be mixed together on both machines. For some this is a benefit, for others you may wish to delete all bookmarks on one machine so as to import bookmarks from the other.

Another caveat: if you are syncing Tabs and Windows between browsers, you probably do not want to use the option to “Show my windows and tabs from last time” within your Firefox preferences, since Google Browser Sync will be doing this for you.

But now that photography has largely gone digital, photographers are finding themselves in the position of having to make decisions on how to store, organize, and secure the lifeblood of their business — digital images – whether in RAW format, as JPEGs, TIFFs, or retouched Photoshop files.

While many different computer programs exist that can organize, manipulate, and retrieve digital images (applications like iPhoto, Adobe Lightroom, Aperture, and iView Media Pro, to name a few), the focus of this article is the physical media used to store and back up this data, regardless of what applications are used.

Direct Attached Storage:
The simplest method of saving data to an external hard drive is to use the physical ports commonly found on most computers, namely USB and FireWire.

Unless your computer is really old, it probably has USB (Universal Serial Bus) 2.0 ports. USB version 1.1 was quite slow, whereas USB 2.0 supports a theoretical data rate of 480 “Mbps” (megabits per second).

(NOTE: I don’t think you need to understand “megabits per second”, so I won’t explain further, but if you do, well, that’s why the gods invented Wikipedia!)

For comparison’s sake, FireWire “400” (a.k.a., “1394a”) is roughly 400 Mbps, while FireWire “800” (a.k.a., “1394b) is – you guessed it — roughly 800 Mbps. A new Apple MacBook Pro (which is a laptop) comes with both FireWire 400 and FireWire 800 ports, and cards can be purchased for use with either an Apple or a Microsoft operating system that provide these ports if they’re not already built into your computer.

Moving up the speed chain comes eSATA, which is roughly 3,000 Mbps – a lot faster than even the fastest FireWire connection currently available. Most computers do not come with eSATA ports, but cards can be purchased that provide them.

Many external hard drives now support multiple connections, e.g., the “G-DRIVE Q” with its “Quad Interface”.

It has four types of connections: eSATA, FireWire 400, FireWire 800, and USB 2.0. So, if you’re using a computer with the high-speed eSATA port, then you’d want to use it to copy data to the hard drive to achieve the fastest data transfer speed (throughput), but someone on an older machine could also use the external hard drive using one of he older, slower ports (FireWire or USB). This allows maximum flexibility. Even if you don’t yet have an eSATA card in your computer, I suggest purchasing a drive with an eSATA port anyway so you can take advantage of that added speed in the future. It’s a sort of insurance or hedge against the inevitable built-in obsolescence of the technology we purchase.

RAID:
RAID stands for “Redundant Arrays of Inexpensive Disks” (some say “Independent” Disks: for some odd reason, the technology world is fraught with strongly contested, ambiguous acronyms).

If hard drives were perfect, there would be no need for RAID, but hard drives can and do fail, rendering all data irretrievable. This can be due to environmental factors (fire, water, a freak Fluffernutter accident, etc.), but sometimes they break through no fault of the owner or any other external reasons.

According to a Carnegie Mellon study, hard drives fail 15 times more frequently than hard drive vendors claim (http://www.pcworld.com/article/id,129558/article.html). If the data you store is critical to your business, you should assume that the external hard drive you’re using to store data may fail at any time. The use of RAID can mitigate this risk to some degree.

RAID 1:
“RAID 1”, also known as mirroring, is most commonly implemented with just two hard drives: everything written to hard drive A is also written to hard drive B. If either hard drive fails, you still have a complete copy of your data. If both drives fail, however, you’ll need to restore from backup (this assumed you have a backup!) If a hard drives fails, you can simply replace the failed drive to rebuild the RAID 1.

The “G-SAFE” is a good example of a RAID 1 solution (http://www.g-technology.com/Products/G-SAFE.cfm). It’s basically an enclosure with two hard drives: all data written to drive A is also written to drive B.

Bear in mind this also means you are paying a price for the redundancy of RAID 1: if each drive is 1 terabyte in size, you still have only 1 terabyte of usable space, since each drive contains an exact copy of the other.

While the G-SAFE is advertised as “The Perfect Storage Solution for Professional Digital Photographers,” that’s just marketing speak: any brand RAID 1 enclosure from any vendor will protect data of any kind.

While my examples thus far have been of products from G-Technology, there are a plethora of other hardware vendors available. G-Technology drives tend to look cool, especially with Mac hardware, but you’ll pay a premium for their style and name. I own some myself, but they’re certainly not a bargain solution.

RAID 0:
“RAID 0” is also known as “striping”: it is actually NOT redundant. (Hence the contention that RAID actually stands for “Random Array of Independent Disks”; again, don’t get me started on the rampant acronym ambiguity!)
In fact, one may argue that RAID 0 is statistically less redundant than using just a single hard drive, since the data is striped between two or more drives to improve read/write performance. With striping between two drives, half the data is written to on drive and half to another. This is useful for video editing when single hard drive speeds are insufficient, but again, it provides no redundancy whatsoever. If you’re buying hard drives for redundancy, do NOT buy a RAID 0 solution.

I bring up RAID 0 because many enclosures are sold which come with two drives that can be configured as either a RAID 0 or a RAID 1 device: this is perfectly acceptable, just be sure to configure it as a RAID 1 for redundancy.

RAID 0+1:
You might see “RAID 0+1,“ “RAID 1+0,“ or my least favorite nomenclature, “RAID 10“. They all mean the same thing: striping with mirroring, so you get the speed advantages of striping (RAID 0) together with the redundancy of mirroring (RAID 1). The disadvantage? If you have four 500 GB drives in a RAID 0+1 configuration, you will get 1,000 GB (abut 1 TB) of usable space. Remember, mirroring always cuts your usable storage in half due to the redundancy.

RAID 5:
RAID 5 requires three or more hard drives and provides redundancy such that if one drive in the array fails, no data will be lost. If two drives fail, you must restore from backup. You’ll find RAID arrays with only three drives, but others with more than ten drives. You lose “n-1” in storage; e.g., if you have three 500 GB hard drives in a RAID 5 configuration, you’ll have about 1,000 GB of storage (about 1 TB). If you have ten 500 GB drives in a RAID 5 array, you’ll have about 4,500 GB of usable data, or 4.5 TB.

Network Attached Storage:
RAID 1 and RAID 5 are not only used in hard drive enclosures that are meant to connect directly to one computer at a time (whether using eSATA, FireWire, or USB). Many servers or “Network Appliances” are sold that utilize RAID 1 and RAID 5 technology with the added advantage that they can be accessed over a network, using Ethernet cables or WiFi (wireless) connections. This allows multiple workstations to connect to a centralized data storage device and access the same network shares. However, accessing a server over the network is bottlenecked by the speed of he Ethernet connection itself, which is often 10 or 100 Mbps. Gigabit (1,000 Mbps) Ethernet connectivity to the server is recommended; you just have to invest in the network infrastructure to support this (i.e., gigabit network switches as well as gigabit network cards in each workstation).

For those who require even faster access to a server, Fiber channel cards can be used from each workstation to a backend server or SAN (Storage Area Network).

The servers themselves often use fast “SCSI” hard drives that are either locally attached or accessed using the iSCSI protocol. SCSI drives are often much faster than IDE hard drives. (Most likely, every hard drive you’ve ever used is an IDE drive). With IDE drives, the hard drive controller is built into the drive itself, so there is no separate card required to communicate with the hard drives as with SCSI. Most servers use SCSI hard drives and most workstations use IDE.

SATA drives have become more common as well, mostly in the server market. They are generally cheaper and slower than SCSI drives, but “SATA 3.0” is almost as fast as SCSI at a much cheaper cost. The SCSI drives also provide greater sustained throughput, so if you need the best performance, SCSI is still king, but a SATA solution is probably more cost effective per megabyte.

Datacenters:
Having your own server requires that you have adequate IT support to deploy and support it. It also requires hat you have enough power and air conditioning to cool the server. Ideally you should have redundant power as well.

This is why it’s often better to collocate your server in someone else’s datacenter, one with redundant power, adequate cooling, redundant Internet connectivity, and offsite backups. They should also have adequate, proven disaster recovery capabilities and offsite backups. They should also have tight security and 24/7 monitoring of the server in case something goes wrong.

If you do locate your own server in a datacenter, remember that your Internet connectivity better be good, since when it’s down you can’t access your remote server!

Another option is to utilize “Managed Services”. Instead of purchasing your own server, simply pay for the service of having a certain amount of disk space in someone’s datacenter. This way you need not worry about how may servers they have, what type of drives they’re using, etc. Typically you pay a flat monthly fee for a certain amount of disk space that is tied to a Service Level Agreement (SLA). If the datacenter that’s hosting your data is inaccessible for some reason, they can offer a refund of free service to make up for the outage.

Conclusion:
Hopefully by understanding the connectivity options to a hard drives (or hard drive array) as well as the different RAID levels will make you a much more educated consumer. Plus you can impress your friends with your refined understanding of storage options!

Simply subscribing to Google Calendars from iCal easily: see How to Subscribe to a Google Calendar using iCal.

However, if you want to sync bidirectionally — add things to iCal and have those sync to Google Calendar as well — I recommend Spanning Sync, which has a 30 day trial and costs only $15 to purchase. While there are actually free ways to subscribe from iCal to Google Calendar, it’s more trouble than it’s worth and doesn’t have the flexibility or simplicity of Spanning Sync.

What makes Google Calendar so great in the first place? Check out So long iCal, hello Google Calendar. To quote one section:

“Google Calendar’s ‘Quick Add’ takes the chore out of adding an event to my schedule… I can hit the letter ‘q’ to open a small dialog box into which I can type an event name, time and date almost as if I were telling someone about it in an email: ‘dinner with Jessi 6 pm 4/22′ adds the event right where it should go. As icing on the Quick Add cake, date spanning works too: ‘Half Life 2 Therapy Camp April 22-24′ creates an event that spans properly. No obnoxious tabbing around to set dates and times right, and no mousing to drag little event boxes.”

Lastly, when using the iPhone, simply point Safari to “google.com/m”
(notice the “m” for “mobile”) to get the mobile version of Google Search, Gmail, Google Calendar, Google Reader, Google Docs, Google News, etc. I bookmarked the site and added it to my iPhone’s homescren. These mobile versions are much faster than loading the full versions from the iPhone.

This Cross Processing with Photoshop tutorial shows how to use Photoshop to achieve a similar effect. While certainly not applicable to all images, this technique has its place in creating dramatic images.

Another, simpler method can be found here.

You can record any window or application, so you can show someone how to use the operating system, or how to use Photoshop or any other application, or do something in a web browser: the possibilities are only limited to your imagination — oh, err, they’re also limited by your operating system! Unfortunately Camtasia only runs on PCs, so if you’re using a Mac, you’ll need to look into paid alternatives like Snapz Pro X or ScreenFlow.

The latest version of Camtasia Studio is version 5, but version 3 is still pretty good and offers a lot of functionality, and now that it’s free, you can’t beat the price! This is NOT beta software: they sold many licenses at full price in fact.

If you’re looking to buy the latest version, you might also want to chck out Adobe’s “Captivate” which is a competing product.

You can also add in text titles and do basic editing. If you want to get really fancy, you might want to buy something like Sony Vegas Studio for more advanced video editing.

You can now backup your files “off-site”, over the Internet. If a water pipe bursts and your PC AND backup drive are destroyed, you can always restore data from an off-site backup.

Offsite backups are nothing new, but were usually done using backup tapes.

A new emerging trend is Online Backups: you backup your data over your Internet connection to a “cloud in the sky” (i.e., servers on the Internet).

A free service from Mozy.com allows up to 2 GB of data backup for free. If you need more than 2 GB of online storage, you can pay $4.95 per month for unlimited space. And since Mozy has graduated from Startup status to being acquired by storage giant EMC for $76 million, I don’t think this service will be disappearing any time soon.

If you have a high speed Internet connection, I’d go with an online backup strategy. Having dealt with the hassle of tape drives and mailing tapes off-site myself, I’m very happy to see the emergence of online backups!
