Veeam Backup & Replication 8 sync and recovery

Veeam Backup & Replication synchronization is different from the mechanism of backup, synchronization is to crawl the virtual machine directly to the other end, the equivalent of a full standby, and then according to the scheduled task to take a snapshot, and based on the configuration to retain the most recent snapshots for failover recovery, This example synchronizes from a 61ESXi host to a 70ESXi host.

1. Add a sync task

Two ESXi hosts, synchronizing the Oracle_vm84 host on 61 to a 70 host.

Create a synchronization job.

Configure the naming convention to retain the number of snapshots.

Configure 10 minutes to synchronize once, here can be configured according to the situation, can be once a day, also can be 1 hours a time.

When you are finished, you can either perform the synchronization directly or schedule the task to execute automatically. The first time will be full standby synchronization, time is longer, different from the backup, is directly using the remote disk read and write synchronization.

Synchronization after the synchronization is complete is equivalent to synchronizing the snapshot.

After synchronizing the virtual machine name, through the task status can see the principle is the direct synchronization of the disk files for the first full synchronization, followed by a snapshot of the way.

You can see the number of snapshots that are retained.

You can view the synchronization status.

After the synchronization is complete, you can see the ready state under replicas, such as.

2. Restore the virtual machine

Synchronous recovery is equivalent to the concept of disaster tolerant, the original virtual machine can not be used, the virtual machine used for synchronization to take over the original virtual machine, virtual machine data has a scheduled task time difference. This is to simulate the shutdown state of the original virtual machine.

Select the point in time for recovery, which is determined based on the synchronization interval.

When you are finished, the synchronization virtual machine is started on the 70ESXi host.

The standby machine has been started, such as.

Close the synchronization schedule task.

The standby machine can be started directly.

Summary: Differences between synchronization and backup. The first synchronization can also be understood as virtual machine replication (which can do migration replication, without preserving intermediate processes), and data synchronization is achieved from the second start with snapshot mode.
