Digital photography has many advantages over traditional film, but unfortunately, security isn’t really one of them. Unlike prints or negatives, digital images can be lost forever in a catastrophic hard drive failure, or even accidentally deleted with a few clicks of the mouse. Here are a few ways Apple users (and those on other platforms, to some extent) can make sure those digital memories don’t vanish before their eyes.

The Best NAS (Network Attached Storage) Devices of 2018 Why buy a network-attached storage (NAS) device? To give a pool of users you choose remote access to large amounts of your data. The best NAS drives 2018: backup, store and access your data from anywhere Network Attached Storage (NAS) allows you to get your important files from any computer, anywhere.

2. Mac Backup Guru is another backup app that specializes in cloning, that is, creating an exact copy of a selected drive. So exact that if the target drive is the one you use as your startup drive, the resulting clone will also be bootable.

1. Store photos across multiple libraries

The best offense for any potential disaster is a good defense: The latest versions of Apple’s Aperture ($79.99, Mac App Store) or iPhoto (free, Mac App Store) not only share the same library format now, they also allow users to access multiple libraries — even those spread across different storage media.

This process is easier with Aperture since the feature is baked into the software, but with a keyboard shortcut or third-party application like iPhoto Library Manager ($29.95, fatcatsoftware.com), the same trick works in iPhoto as well.

The concept is simple: Move older, unused, and duplicate images to a separate library stored on an external drive, preferably one that doesn’t see daily use. By launching Aperture or iPhoto with the Option key held down, you can easily switch between libraries at will; with the application open, File > Switch to Library does the same.

This tip works best when libraries are stored on some kind of redundant storage like a Drobo or network-attached storage (NAS), or in conjunction with the advice offered in our next method, which also has the benefit of freeing up precious internal space on modern flash storage drives.

2. Archive photos in the cloud

If you happen to be a person who isn’t very proactive about keeping a good backup of digital photos, syncing them to the cloud is a great way to “set it and forget it.” There are an endless variety of services with Mac desktop clients, and many of them offer generous amounts of free or cheap storage as well.

Some of the more popular options include Dropbox, Google Drive, Microsoft OneDrive, MediaFire, and Bitcasa, and many offer mobile apps that can be configured to automatically back up the Camera Roll of iOS devices.

The same services also work with libraries from desktop applications like iPhoto, Aperture, or Adobe Lightroom, although you’ll want to make sure to save these files in a folder on internal or external storage that’s set up to sync from desktop to cloud for faster local access, rather than a network-based drive dependent upon internet access; Bitcasa offers such an option, and other cloud services can do the same using software like ExpanDrive ($49.95, expandrive.com).

3. Use cloud photo services as a backup

Speaking of the cloud, mobile shutterbugs are increasingly embracing the convenience of carrying entire photo collections in their pocket. Services like Picturelife, Adobe Creative Cloud, and ThisLife make it easy to back up photos from iOS or Android devices as well as Mac or PC, providing an additional layer of security plus the tools necessary to organize and edit photos from anywhere, no matter which device or web browser you happen to be on at the time.

However, consumers should be wary of putting all their eggs in one basket. As the demise of startup Everpix in late 2013 taught us, nothing is forever. Remember Kodak Gallery? (They wound up being bailed out by Shutterfly, the online print service that now owns ThisLife.) While Revel is backed by longtime software giant Adobe, companies launch, promote, and eventually fold products all the time.

It’s a good idea to find one you like and stick with it, but also use apps like Amazon Photos (which offers free photo storage for Prime members) or otherwise import backup copies on the desktop for redundancy.

If you're concerned about cost, then there are a number of services you can use for free, without limit:

Amazon Prime customers receive a number of benefits, not least free delivery, Prime Video, Prime Music, and book borrowing from the Kindle Prime Library. However, one understated benefit of Amazon Prime membership is the ability to store an unlimited number of photos on your account. Uploading is easy, and once done, so long as you remain an Amazon Prime customer, your photos will remain online and private with your account.

Google Photos is another free option for putting your photos in the cloud for free, and without limit. The only caveat is that Google will convert high resolution images into a slightly lower resolution. If that sounds drastic then don't worry, as for ordinary photos you're really not going to notice the different. You can organize photos into albums, and a neat timeline feature means you can scroll through them by date.

Facebook is another online service where you can upload your photos for free, without any apparent limited. As with other services, you can set them up into albums, which is handy as otherwise Facebook will simply display the most recently uploaded in your photo tab. As with your Facebook posts, you can set sharing permissions, so that your photos are visible only to you, only to named friends and family, or else public for anyone to see.

4. Print them out (just in case)

Unless your hobby is scrapbooking or you grew up in the Fotomat generation (kids, ask your parents), printing out thousands of digital photos might seem like a waste of money, time, and trees. Just because we’re so enamored with paperless photos now, the time may come where having a closet full of prints might be preferred or even come in handy. At the very least, they’re a decent hard copy that can be used to scan back into the computer, should the worst-case scenario transpire and your digital memories get wiped out.

Thankfully, prints are reasonably inexpensive these days. Services like Shutterfly offer unlimited photo storage from desktop or mobile devices (and that counts as another backup, score!), and are quite aggressive with weekly deals to make prints, custom books, and other photo-based products on the cheap. And don’t forget your local drugstore — Walgreens, Rite Aid, CVS, and others offer similar services with the convenience of being able to pick them up in store and save a bundle on shipping.

5. Backup, rinse, repeat

Last but not least, we can’t stress enough the importance of backing up your digital photos (and while we’re at it, videos, too). Many consumers don’t even bother printing their photos anymore since they can easily carry entire collections on a smartphone or tablet. These files are effectively your “negatives,” and should be treated as such — even if that means offloading a copy onto some form of storage media and shoving it in a shoebox, similar to what generations past did with the real thing.

Of course, keeping two copies of your digital photos in the same location isn’t necessarily a good idea, either. A fire, flood, or other natural disaster could wipe out everything you own in a heartbeat, which is where offline storage comes into play. Services like CrashPlan ($5.99 per month, crashplan.com), Carbonite ($59.99 per year, carbonite.com), or LiveDrive ($6 per month, livedrive.com) can securely back up entire desktop systems (including the digital photos stored there) for pennies per day without user interaction.

Now would also be a great time to invest in a new high-capacity USB 3.0 external hard drive (they’re quite cheap these days), and flip on Time Machine, the built-in backup software that comes standard with OS X. Many inexpensive NAS devices also support Time Machine, and products from Synology, ASUSTOR, and others can even access files remotely via mobile apps. Just be sure to make a backup of your backup every few years in case the original drive decides to meet its maker!

Unfettered File Access From Anywhere

In this age of high-resolution photos and near-constant video capture, the storage space in your PCs and mobile devices fills up faster than ever. While you can certainly use an external hard drive for offloading and backing up files from your PC (and by extension, from your phone), if you disconnect the hard drive and leave it in your office, you won't be able to get to those files from home, and neither will anyone else. There are ways to allow other users to share and access the files on your hard drive, but they may be challenging to implement, or carry security risks.

Instead, consider a good network-attached storage (NAS) device. As its name implies, a NAS is high-capacity storage that connects to your home or office network so that you and other users you designate can access your files from mobile devices and PCs without plugging in to the drive. Here's what you need to know to choose the right NAS.

What Can You Do With a NAS?

Once you decide that you need to store files on a network drive, you then need to figure out what you mean to do with them, in order to determine what kind of NAS you need.

For example, sharing access to Office files like spreadsheets and Word documents with your coworkers is a simple job for a NAS. If you're using the NAS to back up your laptops overnight, that's pretty straightforward, as well. But if you're serving HD videos over your home network to two tablets, a laptop, and your smart TV, all at the same time, you'll want a NAS with higher specifications for memory, processor, and network capabilities. You'll also need a more powerful NAS if you want to store big media libraries, like a collection of 100,000 stock photos, for your graphic arts studio.

Like any computer peripheral, the features offered by the various NAS units vary greatly to meet these different demands. So you'll need to understand the terms and features before you go shopping.

NAS Drives: Buying Basics

Nas Drives For Mac

Since a NAS device is, at the simplest level, just a container for a hard drive or drives (with some added intelligence), the number one spec for any NAS unit is its potential storage capacity, determined by the number of drive bays it includes. Most consumer-grade and home-office NAS units have one or two bays, while models designed for the office have four or more. But that's not an absolute guideline.

We don't generally recommend NAS drives with just a single bay, unless they are to be used strictly for backing up data that will also reside on computers on the network. That's because of the lack of redundancy out-of-the-box. (Some single-bay NAS drives will allow you to attach a second NAS device or an external hard drive, to that end.) You don't want the only copy of your data residing on just one drive on the network. Also, the drives in these single-bay devices tend not to be user-accessible, if the NAS ships with a drive pre-installed.

Top 5 Best Personal Accounting Software for Mac and Windows #1. ISkysoft PDF Editor 6 Professional Accounting requires documentation and therefore you need the best PDF software to make it easier to not just organize the documents but also edit and maintain them. In this article, we are going to be looking at some of the best personal accounting software for you to choose from. Yet, choosing the right one can be just as difficult. Some are free, others charge a small fee but each one has features that are designed to make it easy for you to keep track of your money.

For most home users who aren't video-file hoarders, a two-bay NAS should be sufficient, provided that you buy big enough drives from the outset if you'll be mirroring them. Err on the high side of capacity, though; it'll cost more now, but you don't want to have to rebuy two hard drives for your NAS to get a higher effective mirrored capacity. Remember: Mirroring takes two physical drives. More on redundancy in a moment.

Buying a NAS: Populated or Diskless?

Some NAS drives are sold pre-populated with disks, oftentimes already formatted for use in a particular RAID configuration, while others come 'diskless.' Each NAS vendor has its own tendencies in that regard. But surprise, surprise: The NAS-device makers who are also manufacturers of hard drives (Seagate, Western Digital) favor pre-populated NAS drives for obvious reasons—they lock in a sale of their own hard drives when they sell a NAS. (Not an insidious motive, mind you, just good business.) The 'indie' NAS makers that aren't drive manufacturers, such as Synology and QNAP, are more likely to sell their NAS devices diskless, though they (or more accurately, their resellers) may also offer units pre-populated and configured with drives for shoppers' convenience.

If a given NAS is offered in both pre-populated and diskless form, we suggest checking out the cost difference and making sure that the drives that are provided in the populated model work out to a good value. With pre-populated-only NAS drives from Seagate and WD, the cost of the internal drives tends to be harder to distinguish from the cost of the NAS unit.

Which Drives to Use Inside Your NAS?

NAS makers that sell diskless NAS drives recommend certain drive models or families that have been tested for use with their NAS drives. This might coincide with the hard drives they actually manufacture, or not. Take a look at these drive-compatibility lists before you buy. If you already own a bank of hard drives you intend to install, you'll want to look for such validation. If yours are not on the list, it doesn't mean they won't work, but if you are buying drives new, it's best to stick with the NAS maker's recommendations.

Some drives from HGST, Seagate, Toshiba, and WD are tagged as specially designed for NAS use. Most of these 'NAS certified' hard drives have been tested to run 24/7/365, which is a bit much for regular, consumer-level drives.

If you are looking at Seagate drives, the NAS-class drives are called the 'IronWolf' and 'IronWolf Pro' lines. Straight IronWolf drives are what you're after for outfitting a NAS drive in a home; they come in 1TB to 14TB capacities, at this writing. IronWolf Pro drives are rated for service in enterprise or commercial situations. HGST's drives are the Deskstar NAS line, and Toshiba's are in the 'N' series. On the Western Digital side, the NAS-specific drives are the 'WD Red,' in capacities from 1TB to 10TB, with the 'WD Red Pro' series meant for enterprise use.

Safe (Storage) Space: Let's Talk Redundancy

As we mentioned earlier, NAS units that have more than one drive are built to offer the option for redundancy, so in two- and four-drive configurations the extra disks can simply 'mirror' the contents of the other drive. Example: A two-bay unit with two 4TB drives would offer only 4TB of usable storage if you leave it in mirror mode. The other drive is in a sense invisible, as it's used to make a second copy of all the files from the other drive in the background.

Usually, the user has the option to reconfigure the drives to gain the capacity of the second drive, if desired. One way you can do this is via 'striping,' in which the data will span both drives. Striping by itself is chancy; under some circumstances, it enhances the speed of reads and writes, since you're accessing two drives at once. But if either disk fails, it's possible that all your data will be lost, so we don't recommend this approach. It essentially doubles the failure risk.

Many NAS units also support a JBOD mode ('Just a Bunch of Disks'), which lets you address each drive as a separate drive letter and save data to discrete drives within the NAS box. This is marginally safer than just basic striping, but any data you save to a given drive is still vulnerable to the failure of that specific mechanism.

It's also possible to combine striping and mirroring across three or more drives for enhanced speed and data security. In such an arrangement, the NAS would copy the data across the drive array in such a way that the failure of one of the drives would allow the NAS to reconstruct the array (and thus save your data) if you swap in a replacement drive. This is mainly of interest to business users that need to maximize both redundancy and data transfer rates.

Media-Streaming Subtleties

If you think a NAS drive will let you stream any type of media you have to any device or TV, keep in mind certain devices will only play certain types of files, and you'll need to get software and hardware to work together to make this happen.

For example, that, ahem, sweet DVD rip you have of Titanic in AVI format will not open on an iPhone without some jiggering. (It needs to be in MP4 format to be recognized.) Software can get around that problem, such as the ever-useful VLC Media Player utility, and some NAS units work with Chromecast, Apple TV, Roku, Android phones/tablets, and other types of hardware. It can be complicated, though, to guarantee that a specific file or file type will play on a given device, so look at the specs of the NAS closely to determine its capabilities.

A late development in NAS circles is special kinds of support for streaming 4K video, and the spec sheet is your friend in these cases. Some NAS with 4K acceleration will convert this high-resolution video on the fly to formats better suited to the bit rates of devices, such as smartphones, that are requesting it. This is an esoteric need at the moment, but know that some NAS makers will charge a premium for some of these features. It's also possible to get such on-the-fly transcoding for other, lesser resolutions. This is where the CPU that powers a NAS comes into play: a low-end Intel Atom versus a much more robust Core i3, for example.

Nas For Mac And Pc

Connectors and Controls

Most NAS drives have one or two USB ports that you can use to connect a printer or external storage drives, letting you add those to your network via the NAS itself. Once they are plugged in, just like everything else on the NAS, they can be shared with all the connected users. A frequent arrangement: A NAS drive will have one USB 2.0 port that is usually used for printer sharing, and a USB 3.0 port that can be used for external storage. (USB 2.0 is much, much slower than USB 3.0, but a printer doesn't need the fast pipe, so a USB 2.0 port is just fine.)

Some NAS units also have a 'copy' button on the front panel designed to make copying the contents of an external drive, such as a flash drive, to the NAS a one-button-press affair. You just connect the drive and tap the button, and everything on the external drive is safely copied to the NAS to a predesignated location.

NAS drives, by definition, will come with an Ethernet port, possibly two for redundancy or channel-bonding (essentially, using two Ethernet connections to enhance speed) with very high-end business models. Recent high-end models may also offer the option for 10-gigabit Ethernet, for screaming data transfer rates, though the throughput of platter hard drives makes this moot for most consumer and SOHO usage cases. (That said, a few models come with a PCI slot that may let you install an enhanced network card.)

A few models will also come with an HDMI port; this would let you use the NAS as a media server with a direct connection to your HDMI-equipped HDTV.

Remote Access: Serving Files From Here to Anywhere

Best Nas For Macs

In addition to the above sharing features, most NAS drives let you send web links to people to allow them to access remotely certain files or folders located on your NAS. Your NAS can thus serve like your own private Dropbox or Google Drive, but with way more storage capacity—and no monthly bill. Many NAS makers tout this. (Look for the much-bandied term 'personal cloud' around this kind of feature.)

With this functionality, you can also access the NAS itself from any internet connection, not just via your local network. As a result, you can download files you need on the road, or stream a movie or music files resident on your home NAS to your laptop in a hotel across the country or the world, network bandwidth permitting. Most, but not all, NAS drives offer this kind of feature, so be sure to do your research before you pull the trigger if it's a must-have. (Ourselves? We wouldn't get a NAS without it.)

Below are the top NAS devices we've recently tested, ranging from simple home-oriented models to multiple-drive arrays that can serve dozens of users in an office environment. Whether you want to serve media files to the rest of the house, keep office documents in a single, accessible repository, or simply back up your digital life from your PCs, tablets, and mobile phones, there's a drive here for you.
