What partitions must be restored with OS?
Hi,
I have read a few old threads on Disk vs partition backup and understand there should be no difference in the archive if all partitions on a disk are selected at backup (I assume this is still so on current TI versions and it's just a UI representation).
I have some queries regarding recovery though.
I'll set the following to assist with an example:
1. C-drive = OS
2. D-Drive = data
For a legacy machine (Win 7 thus no UEFI) I have the above AND "system Reserved" partition.
Where I wish to recover the C-Drive only to restore OS function, what is the impact of restoring/not restoring the "system reserved" partition?
For a UEFI enabled machine (Win 8 or 10, GPT disk formatted NTFS I would guess?):
A. what partitions exist, and what must be restored to restore OS function.
B. what is the impact of not restoring different partitions for the data or OS in general?
Where I am coming from with this is that in the past I have restored the C-Drive only, and listed in my TI 2014 OEM I have had a partition called 'MBR' (is this just the system reserved?).
Everything seems fine but I am uncertain if there are elements stored on the Reserved or UEFI partitions that change with data/OS installation and thus have potential to create a mess.
Alternatively, I would not want to recover the reserved partition and kill or corrupt data on D-Drive.
Have I confused you yet? :D

Thank you.
Just to be clear - are you saying for win 7 Acronis shows the system partition in Partition mode, but on a UEFI disk it will not show all of the hidden partitions in partition mode and should be used in Disk mode?
I'm all sorted for redundancy and layering of my backups I think - but thank you for considering that aspect in your answer as well.

Just to clarify, in ATIH 2016, the choices are to select as the source for a backup:
Entire System = All installed disks and partitions, which can include connected external drives.
Disks and Partitions = The choice of selecting one or more entire disks (including all partitions on the same) or selecting individual partitions on selected disk(s).
Files and Folders = As it says, selected individual or groups of folders and/or files.
When choosing Disks and Partitions, it is important to set the view to Full partition list in order to reveal any hidden partitions that are present, such as the System Reserved partition on Windows 7 - 10 MBR systems, or the UEFI partition on those same systems. Note: Acronis will rebuild the MSR partition on UEFI systems on recovery - there have been some lengthy discussions on this in the forum recently.
Hope the above is clearer.

Certainly is :). Thanks you
I'm back on TI 2014 until some changes occur with 2016 (or 2017 :P) so was looking at slightly different options.
