Make sure your backup strategy is protecting you.

We talk a lot about backing up around here; I’d say it has been the third-most popular topic here on the OWC Blog, behind memory upgrades and price specials. In fact, OWC Mike H. posted a piece about backing up early last week.

However, this time around, I’d like to take a slightly different track that we don’t always cover – even with automated services like Time Machine, backing up still needs to be an active process.

In the interest of full disclosure, I’ll relate that this particular topic stems from recent personal experience. Earlier this month, my father (who I help with the upkeep on his Mac mini at his company) had his main hard drive fail on him.

“No problem,” I thought, “I set up an automated nightly backup on the system. All I need to do is replace the internal drive, then restore from the backup and we’ll be good to go.”

Unfortunately, it wasn’t quite that simple. Sure, we made annual backups to CDs, mostly for record-keeping purposes, but trusted that backup software to do the rest in between. The problem is that for some reason, the backup routine had stopped sometime over April of last year. As it had run reliably for quite some time prior to that point, we’d never checked it for consistency – that was our major mistake.

As a result, none of the data created since the beginning of the year was backed up when the hard drive went bad. Considering the amount of money involved with the data (I won’t go into details, but it is rather significant), the concept of losing it all is pretty much catastrophic.

There are a pair of lessons we can learn from this story:

1.) Automatic backups need to be periodically checked.

Check your backups from time to time just to make sure all the data is in good shape. In my case, it would have also helped to determine whether or not the darn thing was backing up in the first place. Believe me, the worst time to find out your backup is out of date or no good is on the day you need it.

2.) Make multiple copies of data you can’t afford to lose.

I also recommend keeping one or more these copies off-site, so if one backup fails (or is damaged, etc.) you at least have copies of the really important data somewhere.

Fortunately, OWC has all the equipment you need to set up or improve your backup strategy. From our award-winning external Storage Solutions, to recordable media, to replacement internal drives for ones that have failed, we have you covered.

Oh, as for our little story above, we were fortunate enough to be able to recover the “lost” data by using Prosoft Engineering’s Data Rescue 3. We hooked the failed drive up to another computer via an OWC Express enclosure, and let Data Rescue go at it. It took about a week to process, but from all the checks we’ve done, it appears that all the data that had once been “lost” has now been recovered.

I love a happy ending.

New iMac machines include SD cardslot

features_ports_imac_20091020Back in August ,when Apple updated their MacBook Pro line of laptops, the ExpressCard slot was replaced with an SD cardslot.  Here in October, Apple again has added this feature to the entire iMac lineup. It’s located just beneath the optical drive on each machine.

This would be a good time to revisit my prior article: What good is the MacBook Pro SD card slot anyway? to learn how to make the most out of this added feature.  It goes into detail on making a boot drive out of an SD card as well as an emergency startup disk.

Additionally, the widescreen form factor of the new iMac lends to using the machines for multimedia displays.  An SD card makes a great medium for transferring your multimedia data between computers.  A DVD quality movie takes up about 2GB per hour of playtime.  With SD cards ranging from 2GB to 32GB currently, one could store up to 16 hours of footage on a single card.  More exciting is the introduction of the SDXC format which as early as 2010 could have us storing from 64GB up to 2.0TB on a single card.

I for one wouldn’t be surprised to see movies, TV shows and other media being distributed on SD cards just the same as we see CDs, DVDs, and Blu-ray discs currently. Time will tell on that one.

What good is the MacBook Pro SD card slot anyway?

Monday, August 17th, 2009 | Author: OWC Michael

SDtotherescueWhile there has been quite a debate over Apple’s decision to provide an SD card slot rather than an ExpressCard slot on the MacBook Pro 13″ and 15″ models, the fact of the matter remains that these machines are available and that many of us will be using these laptops. So how do we make the best use of our new port?

The first few suggestions are obvious – use the card reader to read the information from your SD compatible camera, PDA, or cell phone. Also use the SD card for removable storage just as you would use a USB flash drive.

In my overall review of the MacBook Pro at its release, I had gone into detail on the storage capabilities of the SD cards to come. And I touched on the bootability aspect of the SD card slot. But what makes this important? Well the answer is twofold. A trim, clean, uncluttered startup disk boots much faster than one with all your programs and files installed on it. As a laptop typically only comes with one hard drive, we used to be limited to using the internal drive with all our saved data and programs cluttering it up, or carrying around a separate external boot drive such as a Mercury On-The-Go or Express. The SD card is physically so much smaller and an 8GB card has more than enough room to hold a trim, clean version of OS X 10.5 (a 16GB SD card has enough room to hold a full version of the OS).  Just make sure you don’t pull out the SD card while you’re still using it.

Additionally and more importantly, an SD card with the operating system installed can be used as an emergency startup disk. In the case of a corrupted drive directory structure, this can come in very handy if you find yourself unable to boot your MacBook Pro. For more detailed information on restoring a corrupted drive, read OWC Larry’s article “Resolving System Problems”

So, how do you go about making a bootable SD card? It’s actually quite simple.

To install OS X 10.5, you’ll need at least an 8GB card (There should be smaller space requirement for Snow Leopard, but we won’t know for sure until after its release).

Format the SD card using disk utility. Under the “Partition” tab, highlight the SD card you want to format. Set the card for one partition and Format: Mac OS Extended Journaled. Give the volume a name and click on “Options”. You need to choose GUID partition table in order to boot from the card. Click “Apply” and the drive will be erased and formatted correctly.

Once formatted, use your OS X 10.5 install DVD and run the installer. Select the SD card as the destination. Follow the prompts until you get to the “Install Summary” page.

Choose “customize” on the Install Summary page and uncheck Printer Drives, Additional Fonts, Languages, etc. so all you’re left with is the “Essential System Software” checked. Don’t worry, it should be grayed out as an option that you can’t accidentally uncheck. This will cut the installation space in about 6.2GB from 11.6GB. Click install and let it work. When its done installing it is ready to use. Along with the OS, it is also a good idea to keep a few disk utilities on your emergency startup disk. Just a few we suggest are:

TechTool Pro
DiskWarrior
ProSoft Drive Genius
ProSoft Data Rescue II
File Salvage

To boot exclusively from the SD card, set the SD card as the Startup disk in System Preferences>Startup Disk.

Otherwise, insert the card and hold the option key at startup to manually choose the SD card as your Emergency Startup Disk.
