Photo Safe II Offers Worry Free Travel Backups

  Recently my family took a three-week vacation overseas, and having
  left my computer at home (hey, it was a family vacation!), I needed
  a convenient way to store all the photos and videos that we were
  taking. Adam had written about this topic a few months ago (see
  "Backing up Photos While Traveling", 2008-08-11 and "More Photo
  Backup Options While Traveling", 2008-08-12) and since he had
  received a Digital Foci Photo Safe II for review after those
  articles appeared, he asked me to give it a real-world test.

  The Photo Safe II is a lightweight (0.6 lb/272 g) portable photo
  storage device and memory card reader, and it proved a welcome
  traveling companion. With it, I was able to back up all our photos
  and videos as the trip progressed, copying them from our camera's
  memory card every few days. I even had enough storage space to back
  up all the photos taken by the relatives who were traveling with us.
  And, although I didn't use it to add data in this way, it can also
  work as a normal USB external hard disk (that's how you move data
  from it to your Mac).

  The Photo Safe II offers nearly foolproof backups. This is due to a
  variety of features, and assisted by the excellent Quick Start Guide
  which provides well written instructions, useful diagrams, and
  anticipates many user questions. Perhaps the most important of its
  features is that you can only delete photos from the device when
  it's connected to a computer, effectively eliminating the risk of
  accidentally wiping out your entire trip's pictures with the push of
  a button.

  Further lessening that risk is the fact the Photo Safe II has only
  two buttons. One turns it on or off when held down, or, when pressed
  and released, toggles between pre-selecting the copy and delete
  functions. The second button then executes either copying (all)
  files from memory card to the device, or deleting (all) files from
  the memory card. The latter action is somewhat safeguarded by
  requiring you to hold down the button for three seconds. And again,
  once photos are loaded onto the Photo Safe II, there's no way to
  delete them using only the device's controls.

  Complicating things just a bit is the fact that the two buttons
  offer a few other context-dependent functions. These include
  recalculating the available space and displaying information (the
  number of files copying and the target folder number) following a
  copy. The former is clearly displayed, making it easy to know just
  how much room you have left. That said, depending on how you're
  using the Photo Safe II, you may find you don't need to check it
  often. With the (now-discontinued) 80 GB model, even after I copied
  several thousand photos and short videos to it, it still had over 56
  GB available at the end of my trip. Of course, if you're also using
  the device as an external hard disk, a more capacious model might be
  required.

  It's important to realize that each time you ask the Photo Safe II
  to copy a memory card, it does a _complete_ copy of the card and
  puts the data in a completely new, top-level, sequentially numbered
  directory, prefaced with the card type. Also important to realize is
  that the copy action copies everything, not just photos and videos,
  but all directory structures as well.

  If you have one memory card, and you choose to make backups during
  your trip without deleting files from the card, the last file copy
  will contain the entire contents of your card. You can then ignore
  all the previous copies.

  However, if you're copying more than one memory card of the same
  type, you need to compare the contents of the device's sequentially
  numbered folders to make sure you get the correct data (since
  they'll all have similar folder names). Apparently it's possible to
  pre-create partitions on the device's hard drive, thus permitting
  you to separate the data coming from different cards of the same
  type, though I didn't try this.

  However, I did successfully use the Photo Safe II with a wide
  variety of point-and-shoot and SLR cameras that utilized the
  following memory cards: SD (normal and HC), Sony Memory Stick Pro
  MagicGate (High-speed), xD, and Compact Flash. The Photo Safe II
  also has slots for many other types, such as CF Type I (including
  Sandisk Extreme III, IV), MMC, SD/HC, miniSD, MS, MS PRO, MS Duo, MS
  PRO Duo, and xD.

  During the trip, I connected the Photo Safe II to a PC running
  Windows Vista (someone else's, of course) and it performed admirably
  as an external hard drive. In fact, I even took the opportunity to
  make a full copy of all our card copies to create yet one more
  backup of everyone's photos and videos!

  The Photo Safe II can also copy data from MS/SD/MMC/xD memory cards
  to a Compact Flash card. This would allow the risk-averse to create
  yet another level of backup. One could perhaps then mail full
  Compact Flash cards back home, or simply have enough peace of mind
  to delete the photos on the camera's primary memory card.

  The Photo Safe II can be powered with its included rechargeable
  battery, via the included AC adapter (sporting a small and
  lightweight wall plug that's compatible with 100 to 250 volt power
  mains), or via USB. Additionally, both the AC adapter and USB can be
  used to recharge the battery within the unit, something that's
  lacking in most cameras (sorry, just a pet peeve there). Included in
  the package is an unusual forked USB cable. One end has a mini-USB
  connector for connecting to the Photo Safe II, and the other end has
  a both normal USB connector for transferring data to a computer, and
  a second USB connector for delivery of even more power to the
  device, presumably to speed charging. Ingenious!

  After a lengthy opportunity to explore the Photo Safe II, I'm left
  with only a handful of quibbles: When the device was connected to my
  Mac, I couldn't see the data within the inserted memory cards, only
  the data on the device's hard drive itself. However, according to
  the documentation, it's supposed to function as a memory card
  reader.

  Also, when powered by AC, I couldn't get it to recognize the memory
  card. I had to pull the AC, turn it on with battery power, insert
  the memory card which would be recognized, and only then could I
  plug the AC in again and be fine thereafter.

  Finally, and perhaps this was just an anomaly, at one point the
  device's power indicator showed a single flashing bar when I was
  using just the battery, indicating a low battery. When I turned it
  off, and then back on, it indicated a full charge for quite some
  time.

  Despite these minor quirks or aberrations, I highly recommend the
  Photo Safe II as the worry free means of backing up on the go. The
  Photo Safe II is currently available in 160 GB ($149), and 250 GB
  ($199) models, and can be purchased from Digital Foci's Web site.
