Windows 10: Hyper-V replication vs checkpoints vs backups

forgive my basic question, but I need you to elaborate on it in a simplified way.Are Hyper-V replication, checkpoints, and backups the same thing just like "apple tree" vs "apple", "apple pit", "garden of apple tree"?and if not, what is the difference between them

:)

 

Hyper-V 2019 Checkpoint Operations fails after a day

We backup our Hyper-V 2019/16 servers containing couple of virtual machines, with Unitrend backup system, which requires checkpoints to be able to back the VM's. When we tested to create checkpoint, it would give the error "An error occured while attempting
to checkpoint the selected virtual machines. The operation cannot be performend while the object is in use". When we check the logs we get the following Event ID: 19100, 18012, 18014.
Normally when we reboot the Hyper-V servers , we are able to create checkpoints for a day or so after which the same issue recurs.

We have used ICACLS to grant the "NT Virtual Machine" user of each VM full access, and ensured that the VHD files and checkpoints are in the same folder. We also ovserved that the .avhdx files which are created would remain and are not able to automatically
get merged to the parend .vhdx file.

This is happening al all our Hyper-V 2019 servers which are part of a domain.

 

Create and Use Hyper-V Checkpoints in Windows 10  

PowerShell really is a nice tool to be used with Hyper-V.

I see you had used default checkpoint names. I like to rename mine to better remember to what point any checkpoint takes me.

Earlier today I recorded video to be sent to Macrium support. I've had contact with them because an issue with Macrium Reflect CBT and Image Guardian features; they simply break OneDrive Files on Demand feature (OD FOD) in Insider builds 17035 and 17040. To demonstrate it I clean installed W10 on a VM, then reproduced the issue creating checkpoint after each step:




I like doing it so, making a relatively short video now by applying checkpoints one after another, capturing those few seconds from that step I want to show, then applying next checkpoint and so on.

Renaming checkpoints with descriptive names tells me exactly which checkpoint I need to / want to apply.

 

Create and Use Hyper-V Checkpoints in Windows 10  


Hi Kari,

actually I do this similarly. Just, I like to keep the date/time in name as it is not otherwise shown in Hyper-V Manager.

So I always create my checkpoints with generated name and then just append some description in Hyper-V Manager.





Like here in Ubuntu, where I've kept track of nearly every step installing stuff on it... sorry just my paranoia *Wink as I'm a somewhat dummy in Linux.
