The distinction between GPT and MBR

MBR, which means "master boot record", was first proposed in IBM PC DOS 2.0 in 1983. The "master boot record" is called because it is a special boot sector that exists at the beginning of the drive. This sector contains logical partition information for boot loaders and drives of installed operating systems. The so-called boot loader is a small piece of code used to load larger loaders on other partitions on the drive. MBR supports maximum 2TB disks and cannot handle disks larger than 2TB capacity. MBR also supports up to 4 primary partitions-if you want more partitions, you need to create so-called "extended partitions" and create logical partitions in them.

GPT means GUID partition table. (GUID means globally unique identifier). This is a new standard that is gradually replacing MBR. It and UEFI complement each other-UEFI is used to replace the old BIOS, while GPT replaces the old MBR. Disk drive capacity can be much larger than the operating system and file system can support. It also supports an almost unlimited number of partitions, limited only to the operating system-Windows supports up to 128GPT partitions, and you don't need to create extended partitions.

There are five new volumes for Windows disks: new simple volume, new spanned volume, new striped volume, new mirror volume, and new RAID-5 volume.

Creating a new simple volume is simple. It can only be sized on one disk and cannot be separated across disks. MBR format partition is used here

You can also customize the disk number or load it into a folder in blank NTFS format

New spanned Volume

New spanned volumes require more than two disks to partition spanned volumes

Here I choose two disks as spanned volumes. The sizes of the two disks of spanned volumes can be different.

It should be noted that the reads and writes of spanned volumes are written to each disk separately.

Once there is a problem with a disk, the data will be incomplete. It is not recommended to use this format volume as a backup disk.

Mirror Volume Mirror Volume is a dynamic volume with fault tolerance. It provides data redundancy by using two copies of the volume or mirroring the data stored on the volume. All data written to the mirrored volume is written to two mirrors on separate physical disks.

It is important to note that the two disks need to be the same size.

Damaging a disk does not affect the integrity of the whole data.

Create a new RAID-5 volume Windows to achieve fault tolerance by adding a parity information band to each hard disk partition of the volume. If a hard disk fails, Windows can use the data and parity information on the rest of the hard drive to reconstruct the data on the failed hard disk.

The same size as the mirrored volume, but also the same size for each disk

After adding another disk, verify and calculate the missing file

Windows backup

The following is based on Windows server 2016.

Add Windows server backup first

There are two ways to backup: one-time backup and scheduled backup.

Let's start with the scheduled backup.

There are two types, one is system backup and the other is custom selective backup.

I choose a custom backup here to back up a folder.

Select a folder to back up

Click next to select the specified backup time

One-time backup

The difference between an one-time backup and a scheduled backup is that there is no regular automatic backup. Other functions are the same, so I won't repeat them here.

Restore the file first delete the source file, then right-click the local backup and click restore

Select the file time of the last backup

Select the location to place after restore

Finally, click restore.
