Can anyone clarify how the Windows Server 2012 R2 Essentials backup utility actually functions when backing up to multiple external USB hard drives?
Example - 2 external USB drives are rotated daily for backup purposes (one kept off site). When carrying out the first ever backup, I assume a full backup of the server is taken and this can be used to carry out a full bare metal recovery if necessary. We then rotate the external USB drive ready for the next backup. As this particular USB drive is being used for the first time, is another full backup of the server taken? When the first USB drive is attached for the next backup, I assume an incremental backup is taken and so on?
- Basically, will I be able to use either USB drive to carry out a bare metal restore or will it rely on the first USB drive being available?
- Am I correct in assuming that a bare metal recovery can be carried on another server with different hardware?
- Are the backups encrypted? If not, what options are available to encrypt the backups?
I look forward to hearing from you.
