Our SME is out for a while and I'm filling in for him so please bear with me.
I have a customer that would like to pause Veeam backups on one VM that is part of an existing datastore backup job.
If I exclude the VM from the existing backup job, will that delete existing backups?
Basically they know existing backups from up until about a week ago are good, so they don't want them to be overwritten as the days roll by and they test things.
I was thinking about restoring a known good backup, just not powering it on and migrating to prod, but I am not sure which method would be best.
There are no snapshots in vSphere that were taken prior to them making changes.
You might have got the anwser that the existing backup will be fine if the related VM is excluded from a backup job.
You can also try Vinchin Backup & Recovery to backup VMware ESXi which also allows you to edit VM backup job like Veeam but it much more cost-effective than it.
This is how you can exclude VMs: https://helpcenter.veeam.com/docs/backup/vsphere/backup_job_excludes_vm.html?ver=120
Regarding the backup, no, the files will keep into the repository, this will happen as you will not be generating new Restore Points for that VM. That is also explained here: https://helpcenter.veeam.com/docs/backup/vsphere/retention_separate_vms.html?ver=120
