BitLocker encrypted backups

My apologies if this double job with other positions. I don't think I've seen the answer in the messages, I searched, but with my knowledge of Bitlocker, I might have seen the answer but not understood.

I want to keep a backup online disk image. I have a HP Elitebook active Bitlocker with a TPM.

What I read, Bitlocker uses strong encryption and the only dangers are social engineering or (in some cases) a black hat having physical possession of the laptop. For this reason, I would rather store the version of the backup rather than trusting the security of the online site or the backup program.

I can do it and, if so, how can I go about it?

Can I load a standalone program to backup and restore on CD and save volumes encrypted on an external drive? (In other words, is the drive encrypted in a format readable by a backup program?) Can I restore the backup encrypted on the original disc and use it as I did before, or do I have to use the Bitlocker recovery key at some point? Does make a difference if I restore a new physical drive rather than one that is currently on the computer?

Is there another method that can be better/more/easier but still accomplish the purpose of storing a Bitlocker encrypted backup?

Or is it a bad idea from the start?

Thank you.

You might be able to do, but obviously you cannot be run simultaneously on the same system that you are backing up.  You need to boot from a USB key-CD/DVD and run a backup program.  As you said, since the entire disc is encrypted, it will not do any recognizable file for a backup program system deal with.

If I read the website, the freeware "Clonezilla" might be able to do what you want.  Because the file system is not recognized, this force the program to create a backup of your drive and your backup will be roughly the same size as your hard drive (whatever it is encrypted does not compress).  So if you have the value of a 300 GB of cloud storage (or whatever is the size of your hard drive is), it might work for you.  In addition, you may need another drive of the same size or larger than your current drive to contain the backup file until you can start on a normal file system and transfer it to the cloud.

Of course a method much less wieldy would be to create a .zip file of only the files you need to archive and then encrypt this file .zip with GnuPG

<>http://www.Gpg4win.org >

GPG (also commercial PGP) existed for a lot longer than BitLocker (at least 20 years), was not known to be compromised and is open-source with many peers (Microsoft cannot claim that).  It uses the same algorithms as the BitLocker encryption.  I personally trust GPG me BitLocker.

  • How can I restore my computer encrypted bitlocker to an external hard drive for bitlocker encrypted after main disk failure?

    I backup that my bitlocker encrypted computer running vista ultimate on an attached USB harddrive external also encrypted by bitlocker.  I have the password both on a USB stick and written down.

    You can restore to normal full image (well close to normal) just using the USB Flash drive and a hard disk formatted, white (with a system partition at least as large as the partition which it replaced)- and, of course, the backup drive.  I see no reason why a bitlocker recovery will be different - after all, it's just not added encryption process (although the exact procedure may vary because you may need to supply a password to authenticate the restore function and decrypt the files as they are restored - that's why it doesn't happen on the CD).  Of course, this means that you must have done a full image backup using bitlocker (not a full backup or a file backup).

    Good luck and I hope this helps. Lorien - a - MCSE/MCSA/network + / A +.

  • How to restore vista OPS hard drive external bitlocker encrypted after main disk failure

    I am running Vista Ultimate and my main hard drive is encrypted by Bitlocker.  I use the backup utility in Vista for backup of that my drive hard main set on a USB attached hard drive which is also encrypted by Bitlocker.  In a case of failure of the primary hard drive and installing a new hard drive, how can I restore my main hard drive (the new drive) to the USB attached bitlocker encrypted external hard? My vista ultimate OPS has been upgraded to the origin of vista home premium and so I did not have the ultimate Setup DVD disk.  I have the disk of vista Home premium.

    Create a recovery disk that the restoration of the backup complete on this topic option (including family Vista drive premium will be not because this option is only available on the Enterprise and Ultimate versions)-should not do anything on bitlocker on it (which will take care of itself during the restore process unless you configure to use a flash drive for protection - then the flash player is also required {but) not a recovery disk different}).  You can make a bootable recovery disk by using http://neosmart.net/blog/2008/windows-vista-recovery-disc-download/ with burning software like: http://www.snapfiles.com/get/active-isoburner.html and, of course, a blank CD (including backup complete PC Restore).  Be sure to get the drive to boot correctly - there are several ways to make records and this requires a way for it to work (but those that are included in the manual or on the website).

    For more information, here's a great article on bitlocker with Vista.   It does not exactly cover your question, but it is very instructive in the process and the technology (and might help you if you are facing a problem on the road) and its good information to have if you use bitlocker (which can be difficult and can cause problems of recovery if you do not just because of the extra complication of encryption (backup and restore). http://technet.microsoft.com/en-us/magazine/2008.06.bitlocker.aspx.

  • If I use FileVault, do I need to encrypt backups Time Machine?

    My main hard drive on my MBP is encrypted with Filevault - that said, is it still necessary to encrypt backups in Time Machine preferences?  The option of my Time Capsule is actually grayed, so I guess I have to format the Time Capsule disk... but that is still necessary?  I guess I'm good with just FileVault enabled, on the Mac?

    No, there is no need to encrypt TM back ups when your Mac has active FileVault.

    Encryption of TM is separate and is kind of FileVaulting like the back of TM ups. If you feel you want your back ups as safe from prying eyes, as you did with your MBP, you can activate the encryption. I do the network back ups to a Mini Mac OS X Server running and have never encrypted them. I can, I elected just don't do it.

  • How to kill encrypted backups? (new iPad)

    Years, I lost my password to my encrypted iPad backup. Apple says that "so much worse so sad' and so I can't get/encrypted backup control for the iPad. So, what should I do when I get a new iPad? Please don't tell me that the poisoned atmosphere is postponed to a new device! I'll be able to restore what does get saved without screwing things up?

    Without the password, you cannot restore the encrypted backup, so will have to put in place the new device as new from scratch anyway.  Do not enable backups on this new device and you'll be fine.

    The requirement for encryption would only "carried on" for the new device if you know the password and where to restore the backup encrypted on the new device.

  • BitLocker - encrypt - decrypt cycle after the replacement of the motherboard?

    After replacing the motherboard of your laptop with BitLocker encryption, the system requires a recovery key. Once inside, connect us to the system as long as decrypt it administrator local to turn off BitLocker and, once finished, activate BitLocker.

    This whole process of disabling and enabling BitLocker may take up to an hour to complete, during which the laptop can not be used by the user.

    Is it there anyway that we can re - initialize BitLocker, after a motherboard replacement, without all the decrypt / encrypt process?
    While the time that the system cannot be used is reduced to just a few minutes?

    Hi Dennis,

    Thanks for posting your query in Microsoft Community.

    I am afraid that you cannot re - initialize the BitLocker after the replacement of the motherboard as the TPM secure is removed or changed. A TPM Module (TPM) is a chip that is integrated into a computer. It is used to store cryptographic information, such as encryption keys. Information stored on the TPM chip may be more secure from external software attacks and physical theft. BitLocker uses the TPM module to help protect the Windows operating system and user data and to ensure that a computer is not tampered with, even if it is left unattended, lost or stolen.

    If your new motherboard does not have the required by the BitLocker TPM, you can refer to the section can I use BitLocker on an operating system without a TPM Reader? in the following article and follow the steps.

  • can application not available I restore the data from an encrypted backup?

    I had to get my iPhone repaired, so I did a full backup to iTunes and reset Once it was fixed, I have restored the backup, but a few apps "could not be restored. In the case of the one that interests me, the app no longer seems to exist on the App Store - I found a link for it from a review of old, but the link is dead: the app no longer exists. Since it is an application that stores data on the heights of our children, and I had used it for a few years, I would like to be able to recover at least the RAW files of my support, even if the app no longer exists. It is not a large amount of data. The backup is encrypted, so none of the files have names that are meaningful, it is impossible to guess what file is associated with that particular application. Any suggestions?

    If you have the app in the iTunes library on your computer you can restore it from there.

  • Everyone is dismayed to see that there is no password recovery or reset secure put in place for encrypted backups?

    I am absolutely amazed that there is no recovery password for iPhone backups encrypted.

    (1) no password is required to access the iTunes application. He launched and the phone connects automatically.

    (2) someone might maliciously put a password. The password for Mac or device using iTunes OSx need at least before setting the encryption password.

    (3) there is no recovery option. None. Tell me: what password-protected sensitive data have NO option of recovery? No secret questions, no e-mail link, no OSx password, nothing. It's horrible.

    I'm in a situation where I remember not the password, and even if I had the foresight to write it somewhere, that the hard copy has disappeared. I suffer a miserable condition where I lose memory. I have reset passwords on all my stuff course often. That's just my new reality.

    I am faced with a situation where if I ever need to restore my device or upgrade to a new, I won't lose all my old texts and local health data in my applications (which is essential for a person with health problems). The loss of memories of conversations for a person who relies on these devices, precisely because I lose my memory is a slap in the face.

    What the risk of COMPUTER audit team approved this feature, Apple? It's quite incredible that a company of your size would be created people to fail like this. Please post a fix in iTunes for password recovery and substitute it. PLEASE, I BEG YOU.

    N ° if there is a way to recover or reset, the encryption would be completely useless.

    Exercise good security practices on the computer where you have installed iTunes and you will not you care about someone maliciously setting a password for backups.

  • Encrypted backup, no password

    Hi everyone, hoping you can help me...

    iPhone 6s was damaged and fell into the water.  Screen completely black, but still able to answer calls by hitting swiping and using earphones.  If anything.

    We have arranged for a replacement by Telstra Stay Connected.

    I managed to save the damaged phone ("blindly") on another computer, however "encrypted" "" was already checked and there was no prompt to create a password.

    So we have now a full and perfect backup stuck inside my computer, but cannot be accessed without this password of mystery.

    Also, without this password that I can't turn off the encryption option to create a new backup off the old phone.

    Please let me know what are my options?  The damaged phone screen is completely black.  The backup is encrypted.  We have less than 2 weeks to return the phone to Telstra.

    Thanking you in advance...

    The more "common" passwords that have worked are 'Apple' and '1234 '.

    How can I disable iTunes backup encryption?

    To disable iTunes backup encryption, enter the password and uncheck backup encrypted in iTunes. Password encryption is always necessary to turn off encryption of backup.

    You cannot use a backup encrypted if you do not have the password. If you have forgotten your password, the only way to turn off encryption on the backup device is to wipe your device and set up as new. Clear deletes all data on your device. If you don't want to erase your device, restore from a backup instead.
