How to backup and restore a veracrypt encripted windows partition effectively

by serge   Last Updated July 07, 2018 16:01 PM

Situation: Windows 10 partition is encrypted with veracrypt

Requirement:

  • Be able to backup and restore the windows 10 partition (as an image)
  • The backup should be compressed (hence needs to be based on en-encrypted data)
  • The backup should not include pagefile, hybernate.sys, etc... (hence needs to be based on en-encrypted data)
  • The backup should not include empty space (hence needs to be based on en-encrypted data)
  • The backup should be encrypted (for obvious protection)
  • Restoring the system should not require to reencrypt the partition

Why?

  • A backup of a full encrypted partition (without decryption first, e.g. using true image boot CD) will be the size of that partition. That is too big of a file, too much space to waste, too long to do the backup and restore.
  • SSD life:
    1. A backup of a full encrypted partition (without decryption first, e.g. using true image boot CD) will significantly impact the life of a SSD drive: if you need to backup and restore a 256 GB partition every week, the life of the SSD will be impacted.
    2. A backup of encrypted data (e.g. with true-image under windows) will require the drive to be re-encrypted after restore. If 256GB and done every week, this will impact the life of a SSD.

Thanks, Serge
