Bitlocker - Image size of of full C-drive backup
My C-drive is about 120gGB of used space (out of 420GB hard disk space) in Windows 10 File Explorer. Before activating Bitlocker, my TIH 2015 .tib file size (with 256bit encryption) was about 30GB for the full C-Drive backup.
After activating Bitlocker, my backup file size (.tib file) is 375GB, with BL suspended.
I have read that with BL, TIH is doing a sector by sector backup.
Is this correct, and does this explain the file size?
is there a way to reduce this file size back to the ~30GB?
