frequency of continuous replication
please tell me the frequency which is used by veeam for continuous replication.
kindly advise whether it is recommended to use this setting?
Or should we configure "Periodically" and choose e.g 20 mins.
Thanks to give your views and recommendations.

Re: frequency of continuous replication
If you set "continuous" as a schedule to your replication jobs, then the next job run will be performed right after the previous job run is finished. It is not possible to say what frequency it would be, as it depends on many variables, such as processing rate, amount of changes, datastore performance etc.
What type of servers would you like to protect with this schedule?

Normally, this would be a better choice. Continuous job schedule may put too much load on your storage due to constant VM snapshot activity.coolgod wrote:Or should we configure "Periodically" and choose e.g 20 mins

Re: frequency of continuous replication
also advise whether "periodically" will have any overlaping schedule?

Re: frequency of continuous replication
Yes, it will, but as I have explained in another topic Veeam backup server will not try to process the same VM with two different jobs at the same (we don't want to mess things up). Your jobs will be put in a queue and then will wait for an available slot in time (this is controlled by the backup server) to start the VM processing.

is 10 mins a reasonable gap ?Gostev wrote: Normally, this would be a better choice. Continuous job schedule may put too much load on your storage due to constant VM snapshot activity.

How long does your incremental job pass take for these VMs?

Also, are you using Application Aware Image Processing for these VMs? Thanks.

Re: frequency of continuous replication
Then it seems like you can only set 30 min and above for your job replication cycle.

[MERGED] Run the Job periodically, continuously..
Hello,
Hope everybody is doing well. I just seen for the first time that there is a option saying "Run the Job periodically, continuously". What or how does Veeam 7.x do the continuously backup process? Does the application-aware image processing check influence the backup process when "continuously" is selected? Is it suitable for servers with DB's?
Thanks,

Re: frequency of continuous replication
With continuous schedule, the job starts next cycle right after the previous one is finished. Performing VSS quiescence every few minutes throughout the day indeed can seriously affect VM performance, so consider doing crash-consistent backups in this case.

Re: frequency of continuous replication
Thanks Foggy, ... got a quick question.
I've checked Enable application-aware image processing, use process setting "Require successful application processing", truncate logs on successful backup only", Index "everything". Do I have to check "Guest quiescence" (Enable VMware Tools quiescence)?
Asking because http://www.veeam.com/blog/how-to-create ... ackup.html mention (on the bottom) to check both.
Thanks...

Re: frequency of continuous replication
It also says: "When you turn on both Application-aware image processing and VMware Tools quiescence, Veeam will use AAIP as the default method, and if VSS is not possible, fails over to VMware Tools quiescence."
So it is recommended to select it, if you have VMs in the job for which AAIP cannot be performed (for example, Linux VMs).

Re: frequency of continuous replication
However, you need to select "Ignore application processing failures" instead of "Require successful application processing", otherwise, failover to VMware Tools quiescence on VMs that failed to use VSS will not be performed, the job will just fail.

Re: frequency of continuous replication
Does the replication only replicate the changes? I would assume so but want to confirm.
If this is the case then continuous replication work load will not be a lot (for servers that doesn't have much changes).

Re: frequency of continuous replication
Yes, replication job sends incremental data only, however, please keep in mind the snapshot overhead. Every time a replication job runs it creates and deletes a VM snapshot that might affect the performance of the application running inside the VM.
