Backup Process Question

[Maurice H]

Hello,

I am looking for general help on how PBS handles data. We have a PBS running at our main building along with our main PVE cluster server, we have 3 other remote sites all with a PVE hosts in that cluster and a QDevice to keep the numbers correct. Every remote facility has a backup storage device mapped to the main site PBS, my question is when PBS performs the backup does the data go straight to the assigned storage or does it travel all the way to the main site PBS and then back to the storage at the remote site?

Thank you.

my question is when PBS performs the backup does the data go straight to the assigned storage or does it travel all the way to the main site PBS and then back to the storage at the remote site?

The PBS process on the PBS server handles new-data-to-be-written. Whether the storage is local or actually remote is a secondary question, the PVE does not even know about. (PVE has no access to storage handled by PBS. And that's a good thing!)

If any data at all travels is a different question. Generally only changed data needs to be transported from PVE to PBS and then to the actual storage.
