Hi,
We replicate around 15VMs where most are Windows DCs and fileservers. Each VM's Veeam repl session of these take from 3-5 minutes. However we have a Linux VM which takes around 40 mins even when no 'important' activity is taking place (I have stopped a few services in the repl time window). Finally we run Veeam from our VCenter server VM and the replication of this VM take 3h40 mins.
Are there any steps we can take with these two issues to reduce the disk hammering for hours? I'm curious if version 6.5 has eased the scenario where Veeam is lifting itself in its hear by replication itself and if there are any general Linux 'sleep' commands we can issue in the nightly repl time window to reduce the job time.
Thanks again for comments on this
regards Tor

Re: Linux and VCenter VMs take a long time to replicate..
Tor,
Also take a look at this topic for considerations regarding backing up/replicating vCenter Server VM.
Regarding your Linux VM, could you please provide some additional details like whether it resides on the same host as other VMs, processed by a separate job or along with other VMs, what are the bottleneck stats for this job?
Please remember that virtual proxy cannot backup itself using hotadd and always fails over to network mode that significantly affects job duration time. You can look at the job statistics, most likely your other VMs are processed using hotadd, which allows for faster source VM data retrieval.bushtor wrote:Finally we run Veeam from our VCenter server VM and the replication of this VM take 3h40 mins.

Re: Linux and VCenter VMs take a long time to replicate..
A general workaround is to have dedicated Veeam VMs with no other role on them, so every other VM can be replicated via hotadd. No need at the end to replicate Veeam Virtual proxies, they can be lost and reinstalled in few minutes, I usually also keep VM templates already prepared for beeing Veeam proxies.

I’m along the same line with Alexander in asking you to provide additional details regarding your Linux VM. More specifically, what is the type of this VM? Just a common Linux VM or VM running specific applications?
Thanks.
Thanks.

In addition to everything mentioned above, make sure the VMs in question are processed with CBT enabled. You can check that by searching for a [CBT] tag next to each virtual disk in the real-time statistics.
