After testing, the bandwidth of the two data centers of the customer is 155Mbit/s, the peak write bandwidth of an application is 9.8MB/s, and the average
The write bandwidth is 300KB/s, the average write I/O size is 4KB., and the bandwidth utilization rate is 70%. Colleagues choose active and standby synchronous remote replication for disaster recovery
Scheme, the scheme:
Send a control command through the backup server, first take a snapshot (or other similar operations) of the data volume that needs to be backed up,
Make a copy, then use the backup server to mount the snapshot volume, and use the backup server to back up the data on this volume to the backup
On the device. What type of backup networking is described in the above workflow?
