Performance Benchmark Amd Ryzen 2400G vs 5600G

My Promox server hit to performance issue.

Therefore I have decided to change my old CPU AMD Ryzen 2400G (4 cores, 8 threads) running on Promox to AMD Ryzen 5600G (6 cores,12 threads). 

Before i made a CPU swap, I did a benchmark & below is the result.

Tool: Sysbench

sudo apt install sysbench

AMD Ryzen 2400G

sysbench cpu --threads=8 run

Result: Refer to event per seconds. Total 7804.45

AMD Ryzen 5600G

sysbench cpu --threads=12 run

Result: Refer to event per second. Total 33266.27

The highest is the number of events per second, better is the CPU performance. 

The winner was AMD Ryzen 5600G (as expected) by 4x

From here, you can start backup to disk or to tape.

Backup Promox Virtual Machines and Container

In today's post, we are going to explore how to protect Promox virtual machines and Container

Natively Promox is included with a backup option.

To begin with:

1. Configure storage where you want to put the backup data

Go to Datacenter > Storage > Add

In my lab, i will select NFS as my target

2. Once you have defined the storage, let's move into creating backup policies

Go to Datacenter > Backup > Click Add

a) Select the target to NFS that you created earlier.

b) Tick VM and LXC that you would like to backup

c) Define mode: Snapshot

d) Compression: ZSTD (fast and good)

e) Define backup retention to keep

Once done, all policies will listed on the screen

Click Run Now to execute the backup. You can view the progress of the backup status by double click the task.
