so in this post: https://www.veeam.com/blog/how-to-backu ... ation.html
If you have enough storage space, create a single backup job for all of your DAG nodes. This will most likely result in better deduplication ratio.
In the next line:
If you want to backup DAG nodes in separate backup jobs, make sure that the schedules don’t overlap and also that all VMs are not being snapshotted at the same time.
So I'm wondering, why it is good to put them into one job, if it shouldn't be done at the same time.
We have 3 Exchange Servers, which are replicating the databases.
So if I start the backup job (when all of those are in one Job), does Veeam know that the data on all the servers is basically the same and therefore backs up only one of those databases?
Or are all 3 Databases backed up seperately?
I would think Veeam backs up one of them and sees that the data is the same (deduplication), but I couldn't find an answer anywhere.
