Using GPT or MBR for a pure backup drive.

I'm not sure if this is the right place to put this, but this forum is the closest I could find to what my question is.

I have got a second internal harddrive to use as a pure backup drive for stuff like pictures, vids, music etc. (no system stuff) and when it asks me to initialize the drive it asks for either MBR or GPT.

To the best of what I have been able too find out so far, the main advantages of GPT are to do with partition size, and drives over 2TB. However since the drive is only 1TB that doesn't seem useful.

However it seems that MBR is more susceptible to boot corruption because the partition and boot data is only stored in one place, whereas GPT has redundant copies. The main issue with GPT seems to be compatibility.

I am really baffled, on the one hand I have seen lots of people say just to use MBT because it is tried and tested and GPT is only useful for drives over 2TB. But then on the other hand since this is a backup drive and I want that data to be safe, does GPT provide any advantage in terms of the redundant partition data, even though it will never be used as a boot drive?

Also I presume that the (non system) files and folders that will go in the backup would be able to be restored from a MBR drive to GPT drive (if upgrading to a new version of Windows in the future) and vice versa? I read that an MBR backup couldnt be restored to a GPT drive, but I am assuming that is an entire system image with the operating system and not just select files and folders?

Any advice would be much appreciated!

Update: So I came across this post/thread here: External backup hard drive, should it be MBR or GPT?

Which seems to suggest that GPT doesnt provide full protection against corrupted partition information, so I am even more confused as to what the advantages are of these redundant partition data files. :S

So far the majority of places i have looked at seem to say to just go with MBR unless the drive is over 2TB (its only 1TB) so unless anyone can provide a really compelling reason to consider GPT I might just go with MBR. :S

Save the important sectors in the Partition Table shown by Bootice. If you have any partition related problems making the drive inaccessible, you can simply restore the saved sectors to regain the drive.(Save the sectors on some other drive and not the same drive)

Saving with Bootice: Lost partitions!



Note: If you have only four primary partitions you need to save only the LBA0 and four NTFS bootsectors ( Volume Boot Record/Partition Boot Record) shown in Bootice. In the sample screenshot above, I have three primary partitions and three logical partitions in the extended partition. I would save all the LBAs/Sectors shown in it with proper identifying names that includes the LBA/sector Number)

You need to take a fresh backup of the sectors only if you change the partition structure ( like adding a new partition, extending /merging the partition/s) any time. That answers the question you posed in the PM.

So if you change the partition structure anytime, run bootice again and save the sectors shown in bootice including LBA 0 since it contains the partition table and that partition table will change when you change the partition structure. After saving the sectors afresh, delete the old saved sectors.
