I am doing a backup copy job across a metered connection. I'm trying to understand how full backup file merge uses bandwidth.
i have 2 windows servers running veeam, and they are copying between each other
so say i have a 10GB full backup.
thats 10G across the wan
next day i have a 5GB incremental
the 3rd day the retention period has to make a merge full file
so it has to inject the 5GB incremental. does the source read the 5GB file (5GB read over the wan) and then inject it back into the main backup (another 5GB) so it actually costs 10G in bandwidth?
and is this the same as a cifs share as a repository?

and welcome to the forums
as long as you have a repository server (usually a Windows machine) on the destination side, the merge traffic will stay in the destination. For SMB / CIFS you need to place the gateway server (settings of SMB repository) on the destination side. Otherwise merges will go over WANI'm trying to understand how full backup file merge uses bandwidth.
