Hello all,

I hope some of you can guide me here. This is the situation:

I had a usb with work docs. They were not encrypted or protected in any way. When I got home, I used Goodsync to sync with a folder in my computer as a back up.

Ok, a couple of weeks back I lost the usb. Bought another one, a SanDisk one which brought an encryption program, SanDiskSecureAccess. I installed the program and now should I lose it, nobody will be able to access them as they need a password. Great.

Now, of course, the sync job will not work as the docs are hidden away behind a password-protected access.

So what I gain in protection I lose in backup.

What alternatives do I have? How should I proceed?

thanks in advance for your thoughts, much appreciated.

If I understand your post correctly, you are saying you must have the specific hardware USB device to even access the stored file?

Anything that makes you dependent on specific hardware, proprietary tools, or methods is generally speaking full of major limitations. However, in some cases one may find it desirable...such as using the hardware-based Trusted Platform Module. However, there are limitations in relying on TPM.
https://en.wikipedia.org/wiki/Trusted_Platform_Module

I'd use a more readily available "known good" software-based encryption program, and make sure it works with standard filesystems. In other words, it encrypts a "normal" file and saves it as a "normal" file suitable for the systems you plan to use...nothing fancy. That way, the encrypted file can be copied freely to any normal storage device (including the cloud) or even emailed as an attachment, without the encryption device/program being required to do so. It's only when someone actually has to use the contents of the file that the decryption hardware and/or software tool is required.

There are numerous freeware tools available that can do that. Even Windows 7 and above (Bitlocker -note1) provide decent strength and reliability encrypt/decrypt tools at that level. Some use normal encrypt/decrypt keys on a standard text file that can be read-from/stored by just about any operating system, others use steganography, and other methods.

Here are some alternatives if Windows built-in encrypt/decrypt facilities are unacceptable.

or do a global internet search on [file and hard drive encryption]


Note1
when using Bitlocker, if you get an "no TPM" error, you might try this procedure to bypass. To help people migrating from Truecrypt to Bitlocker, Truecrypt.org provided this after they discontinued Truecrypt.
How to disable Trusted Platform Module (TPM) in BitLocker:

Data will still be strongly encrypted, it just won't provide the additional security that depending on TPM hardware provides.
