Hyper V VM Snapshots versus VHD backups

Hello,

My question is about best practices about having SnapShots and VHD backups of Virtual Machines hosted on Hyper -V

I know that Snapshots is not meant for substitute for Regular Backup and mostly meant for testing configuration and development purposes , Having VHS backups are better for backups.  But I would like to know expert's ideas about using these techniques and best practices. Personally I am not fun of using snapshots of production Servers believing that it might create some instabilities especially tree-like snapshots, if it is the right term, more than linear snapshots.  ( Term snapshots might be different in HYPER-V world but i think you know what I mean by snapshots in VMWARE ). But on the other end having VHD backups might require storage spaces.

Please let me know what would be your approach when it comes to leveraging HYPER V Virtualization technology for backup and restore operations without using any 3rd tool but just natively and I am definitely aware of the other approach for back up restore operation but my question is specifically about leveraging HYPER V virtualization technology

Thanks in advance

Don't use snapshots except for very limited reasonings I only use them before sysprep/capture so I don't have to worry about rearm counts and remove the snapshot after the capture.  I use Veeam Backup and Restore for my hyper-v environments

Snapshots are not backups, and should not be used for such.

we don't use snapshots for any purpose, and we use the correct third party backup software to make backups of VMs, before we make any production changes. The reason WHY, any VM running on a snapshot, has performance issues, with the disk, because of the method differencing works, Hyper-V or VMware.

So implement a backup technology, there are plenty to select, and when you use them check they do not leave your VMs running on a snapshot.
