I've taken a Backup + System Image on my External Drive, *Let Windows Choose* option... if I use TrueCrypt on the External Drive folder containing the System Image & Backup, Q1 : will it work properly ? ...as in will the system be able to get restored from it ? ...or will it have any issues, like when files need to be used during boot-time for restoring, the system won't be able to get access 'coz of TrueCrypt ? Q2 : will Windows 7, be able to do incremental backups on it ? Q3 : should I instead use BitLocker ? ...will that be better in this particular case in any way ? Q4 : can System Images, be updated incrementally also ? Cheers !
