They clearly did take extra time with this one, as originally it was scheduled for mid-December - so hopefully, this build is solid and everyone who was waiting to upgrade to vSphere 6 can finally proceed.
VEEAM BACKUP EXCHANGE UPDATE
Most importantly, VMware has finally made the long awaited vSphere 6.0 Update 1b build available for download last week, and it lists the infamous CBT issue as resolved.
VEEAM BACKUP EXCHANGE OFFLINE
Telling all the users as they come in to work that you've just had to initiate an offline defrag won't be the best start to a day that you've had.Text I hope everyone had a great festive season, is fully refueled and ready to rock 2016! Monday will be my first day in the office, but I already have some news to share. There's a not insignificant chance of having a dirty shutdown and borking your DB. I would be careful about restarting the server if it is in the middle of a backup operation.
VEEAM BACKUP EXCHANGE FULL
Whether it's a full weekly backup of something (or everything) or something else.
Since this only seems to happen once per week, I would say the backup is coinciding with some other scheduled task to create a "perfect storm". If, in addition to that, the backups are being run over the network and are bottlenecked by the network speed, this can drag out for hours or even days in some cases. For instance, if Exchange, which is very write-heavy, and Active Directory, which is also somewhat write-heavy, are accessing the same R1, R5 or R6 set while Veeam is trying to backup VMs on the same array, you will see latency skyrocket and all kinds of weird stuff will happen. Same thing happens sometimes when removing the snapshot as Kirsten mentioned.Īnother issue that can compound this is disk contention.
If there's no failover setup, the service will just go offline. With Veeam we normally see the VM lose connectivity when the snapshot is initiated. Not a very sophisticated method, but I didn't find anything better. I've set up nightly reboot of Exchange at 4 am (usually 3 hours after the backup job is finished) just to make sure that the problem won't persist until morning (if it happens). Running Veeam Backup & Replication 8 with all the newest updates.Įdit: I didn't find a perfect solution yet. My best guess is that it’s related to Veeam (Exchange starts reporting errors around the time when Veeam makes the backup). I've dealt with it by either waiting until Exchange finds its way back to DC or by restarting Exchange. It doesn't happen every night – maybe once a week. There are no errors on domain controllers and it’s not likely a networking issue – all servers are virtualized, some on the same host (so it’s probably not a faulty cable). “Unhandled Exception "Could not find any available Global Catalog in forest mydomain.local.Įvent ID: 1” (event ID 1! that's almost like finding Patient Zero!) Message: Could not find any available Domain Controller. The service will retry the operation in 15 minutes. All Global Catalog Servers in forest DC=mydomain,DC=local are not responding: The backup job finishes around 1 pm, but Exchange sometimes doesn’t come back online often until 7 am, which is way too late for our users.Įxchange Event Viewer comes up with number of errors – most of them point to Exchange being unable to contact our Domain Controller: Our Exchange 2007 (Windows 2008 R2) randomly becomes unavailable, especially at night when the backup job starts (Veeam).
