I backup my Hyper-V machines on my main server periodically. I have also turned on replication on different machine where I have also more storage space so my backup VM images go to this secondary machine.
Question is - when I backup replica will I have problems with restoration of VM if I would like to restore replica VM on main hyper-v server?
Can I just backup my replica VMs and avoid unnecessary file transfer between servers?
Can I just backup my replica VMs and avoid unnecessary file transfer between servers?
You can backup replica VMs , but the result might be not as you expected .
Because :
"
-Only crash-consistent backup of a Replica VM is guaranteed.
-A robust retry mechanism needs to be configured in the backup product to deal with failures. Or ensure that replication is paused when backup is scheduled.
"
This artilce may guide you in the right direction .

I am running two physical Windows 2016 servers in a clustered environment. The backup solution is Veeam Backup and Replication V11.
I have a replication job that has been failing regularly because the host server isn't merging the production checkpoints after.
I have to manually shut the guest down, wait for the checkpoints to merge, then power it back on. THe replication job then runs successfully but within 1-2 days the same issue occurs and I have to go through the same process again.
The guest OS is Server 2019 core.
The Hyper-V Worker event logs for the FAILED replications only show that the virtual hard disk is being used by another process.
I logged a ticket with Veeam, but they confirmed nothing more than it not being an issue with their software - they can see that post replication, the command is sent to merge the checkpoints.
I would really appreciate any ideas, help, suggestions.
Thank you.
My server configuration is 4 GB Memory / 80 GB Disk / SGP1 - CentOS 7.6 x64.
My redis version Redis server v=4.0.11 sha=00000000:0 malloc=jemalloc-4.0.3 bits=64 build=4caa563e40a30492
This server is dedicated to Redis only
From the picture you can see there is a user called Redis and under is user there are two processes which is causing high CPU uses. I have no idea what is the purposes of these two commands. Is this harmful to my server should I keep them??
sysupdate and networkservice seem to be malicious services running in your system. Maybe somehow hackers got into your system and upload some scripts which are taking too much of your capacities. Most probably they are mining. So follow the below steps
stop that services
backup your redis file
restart your server
you can reinstall your redis
better to hire some consultant for hardening your redis server
We have checked both Redis installed in Azure VM and Azure Redis Cache both are working same I can't see a difference in the performance Have anyone used both in large scale application if so can anyone share the performance and durability of both ?
Have analysed the following
Monitoring
In-zone replication
Multi-zone replication
Auto fail-over
Data persistence
Backup
Pricing
SSL Authentication & Encryption
All the above Azure redis have the upper hand
Still I want make sure which one is the best
Does using VM has any bottlenecks ?
I would go for Azure Redis Cache. Mainly because its fully managed. At the end of the day you do have nodes under the hood. But why should you care for maintaining a VM? Hotfixes? Patches, Seucirty Updates ..etc ..etc.
I would ask the question the other way around. Why should you use VMs at all?

I am currently using Unison across 2 computers (server and laptop). I need to create another connection where I can timely backup my data from server.
laptop <--> server -> backup
Here the connection to backup from server can be unidirectional. Is there any way to accomplish this?
This is a very common thing to do. When setting up Unison across multiple machines, you should prefer a star topology. So if you can, you should run another instance of Unison, along with any backup-related scrips, on your machine where you are storing your backups. It should look about the same as your setup on your laptop (depending on where your backups are being stored).
I would like to setup a free/custom solution to perform failover for VMware ESXi.
The setup is as follows:
2x Physical servers each with independent storage.
For each physical server there are 2x Win2k8 Enterprise servers.
In the case a physical server completely fails, we want the other (for convenience sake we can assign it with a slave role) to resume operation.
For this to occur, we need to somehow do continuous replication of the virtual servers, and in the case of the primary server failing have it take over the IP, start the virtual machines and continue operation.
I am new to VMware ESXi myself, but I am trying to research alternative solutions to the expensive VMware licensing for failover.
Thanks.
Take a look at Veeam Backup & Replication.
