2. Manage Azure Active Directory (AAD)

3. Manage Azure AD

IV. Implement and manage mixed identities

Traditional backup-belt library

Magnetic disk

Virtualization

Do not install agents on each virtual machine for backup. (simplify backup configuration)

Communicate directly on the virtualization platform and back up the virtual machine directly.

Previous backups required consideration of Winodws,Linux,Unix.

With the emergence of SSD, the space of the hard disk increases with it.

SATA disk appears to be large in capacity and cheap.

SSD is the mainstream of production data, and SATA is the mainstream of backup.

In the era of cloud computing, how to do backup?

Azure, why back up?

One piece of data, Microsoft promises, one piece of data has three pieces of data.

If there is a high availability of the site, there are a lot of data.

Purpose of the backup:

Azure Backup-

1) Why back up?

1. Preserve historical data

Hospital data compliance, retain multiple data for audit use.

2. Data loss

Disaster or failure

It is generally not easy to happen unless a catastrophic problem occurs throughout the data center and will be lost.

If there is a data center-level disaster, data will be lost.

Human factor

Commercial banks, database engineers operate on the test library, clean up the test library, as a result, delete the production library.

Even if there are two places and three centers, it is useless. Once deleted, they will be synchronized to the two places and three centers.

Commercial banks, it is stipulated that suppliers are not allowed to operate servers, but only by customers.

It is possible that an automated script shuts down and a lot of virtual machines may be lost.

Viruses, malware (ransomware)

The data center was encrypted by a Chinese company, making it impossible to recover.

2) back up what?

1. Azure

Azure Virtual Machine (VM)

Azure File Share (file sharing)

Sql Server in Azure VM

2. On-Premises

Recovery Serices Agent (Agent)-

System State (system status)

Files And Folders

Azure Backup Server

Hyper-V VMs

\ VMware VMs

\ Bare Metal Recovery

\ MS Sql Server

\ Exchange

\ SharePoint

3) where to back up?

Recovery Services Vault (recovery service vault)

Logical Target

1 > Location, backup location

Virtual machine and backup are in the same location

2 > Replication Type

Local redundancy

Locally-redundant

Backup to another data center

Geo-redundant

3 >

4) when to back up

1. On Demand

Manual backup

2. Scheduled

Schedule backup

Virtual machines are backed up only once a day

FileShare, backup only once a day

5) how long will it last?

1. Retention

How long will it last?

Scheduled

Retention

Do it through strategy.

In Azure backup, do the backup configuration as shown below.

First, backup strategy

Second, back up the local server

Third, backup container-backup Item, virtual machine, or file sharing, recovery point of virtual machine, file recovery point

Fourth, associate backups through backup jobs

Full- full backup, daily full backup

Differential Backup, differential backup, first full backup, second-n times, based on full backup.

In order to make a full backup.

Incremental Backup, incremental backup, full backup for the first time, and only additional backups later.

Depending on all the previous backups.
