I found some topics in this forum about backup to removable storage by copy the backup target directory to mobile (USB) disk(s) with explorer or tools like robocopy.
The problem is that the changed full recovery file (.vbk) will change and robocopy or other tools copy a huge file although only a small part of this file changed.
What about this idea: let veeam manage the offline disk(s).
Additional to the periodically scheduled backup jobs with persistent storage target, configure manual backup jobs (incremental synthetic), which will be started manually after plug the mobile disk(s). So veeam know what is to do and it will do this more quickly.
Does this will work? (I never worked before with veeam, but from now I will do

Thank you in advance
