How to backup and restore a veracrypt encripted windows partition effectively

0

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

“en-encrypted data” - What? – Ramhound – 2018-07-07T19:07:28.640

Your disk is eventually going to get reasonably filled, so you won't gain significant time by skipping empty space and such. If you need to restore (backup is a read-only operation, right?) your disk weekly, you have much more important problems than the life span of your SSD. Also modern SSD don"t wear out that fast... Finally, image backup isn't a backup, getting individual files from that is very complicated. – xenoid – 2018-07-07T22:14:44.640
