At the same time we want to defnintely be safe during the Snapshot Removal. So not sure how effective it is.Į) Monitor the critical ones manually - datastore, see which disk is being pointed to in Edit settings etcĪ) Once the VMs are identified the snapshots need to be removed during off peak hours.ī) For VMs with very large snapshots (> 20 GB) - Schedule downtime and then do a Delete AllĬ) For VMs with snapshots within the limit so a Delete All off business hours but with the server powered on.ĭ) I believe once we get in a regular cycle we should be able to minimize any large snapshot files going forward.Į) The major issue is that we want to minimize downing servers as it requires too many people to approve.
I defined it on a VM which I knew was running on large snapshots but it didnt trigger. I have checked out one alarms which triggers when the snapshot file goes beyond a described limit. The server failures and outages have been because the snapshots have been allowed to grow very large - 30 day old and 800 GB in some extreme cases.įor detection I have the following options in mind:Ī) Have scripts being run daily to identify VMs running on snapshots - if someone has a link to a tried and tested PowerShell script please suggestī) Plan maintenance on the servers identified in part a.Ĭ) Snapshots are taken on production servers only by the backup process usually so I believe during business hours we should not have any VMs running off snapshots.ĭ) Define vCenter Alarms.

So for the immediate relief I have pput together a plan and I wanted the group to review it and make suggestions:Įnvironment: 40 Dell hosts running Esxi 5.x We also had a datastore overrun which caused a crash. However in the meantime we are facing outages with multiple production servers as they are found to be running off snapshots. I am working with Veeam to do root cause analysis and plug this problem. Its a random issue and not affecting any one kind of server in particular.
Veeam backup temporary snapshot software#
As a temporary step, I had configured the Veeam services to run with domain administrator credentials asking to customer, he had changed the administrator password in the previous days.We are currently facing issues where our backup software Veeam is causing orphaned snapshot files to be created. Since Veeam Backup is a windows-based software, my guesses went straight to the credentials used to run the backups. The strange thing was to have several jobs, all configured in the past days, going on running smoothly. Those timeouts made me loose almost two hours of tests, but at the end I managed to find out the problem.
Trying to run some of those failing jobs manually, I saw the job was stuck while trying to copy the vmdk disk file for about 20 minutes, without any single byte transferred.
Logon attempt with parameters Port: 443 Login: VMX Spec: Snapshot mor: Transports: ] failed because of the following errors:
Veeam backup temporary snapshot windows#
I was configuring a windows server for Veeam Backup & Replication 6 at a customer, and after some days of work I got a weird error while running some new backup jobs just created: Error: Client error: Failed to open VDDK disk VMNAME/VMNAME.vmdk] ( is read-only mode - ) Failed to open VMDK. 0 Flares Twitter 0 Facebook 0 LinkedIn 0 Email - 0 Flares ×
