This KB article from Macrium details the various possibilities with respect to BitLocker. But the short version is, it depends on a couple of factors both at backup and restore time. If the backup was captured while the volume was locked, then it will always be restored locked -- but that's not ideal because backups of locked volumes will be much larger since Reflect will have to capture every block in the partition, including free space, AND compression doesn't work on encrypted data. If the backup was captured while the partition was unlocked, then in general it will be restored in the clear (and you will get a warning about this). The exception is if the restore target is already using BitLocker, the target is unlocked at the time of restore, AND Rapid Delta Restore can be used (requires a paid Reflect license and some other conditions). This is the typical scenario when you're just rolling your system back to the state of a previous backup rather than setting it up from scratch AND you either have auto-unlock Rescue Media or you manually unlocked the partition using manage-bde. In THAT situation, Reflect supports restoring a backup in a way that preserves the existing encryption on the target. When you are restoring a partition that had BitLocker, you can check what will happen beforehand because the final step of the restore wizard where you see a summary of what will happen indicates the type of BitLocker restore that will occur: BitLocker Removal (restored in the clear), BitLocker Live Restore (preserve target encryption), or BitLocker Encrypted (source was locked at backup, so restored instance will be encrypted). An extension of the capability I just described comes into play when cloning. If you clone an unlocked BitLocker partition, the clone target will be in the clear. But if you then enable BitLocker on the target, future clones that use Rapid Delta Clone will preserve the unique encryption of the source and target, i.e. they can have different passwords, Recovery Keys, etc. I think I remember reading that VeraCrypt can be made to work in WinPE to unlock partitions in that environment -- I think you just need the VeraCrypt Portable application files available? -- but I don't remember for sure, and I don't know if unlocking a partition prior to restoring onto it would preserve VeraCrypt encryption.
