restore while backup job is running

We are using sql server 2008, planning to migrate to sql server 2012.

We have an ETL process (job 1) that runs each night to restore data from server-A to server-B; We also have a backup job (Job 2) set up by our DBA, that runs each night to backup server-A database. Depending on the time taken by job2, it sometimes overlaps with job 1 and locks job 1 out. Can we setup the back up job in a way that it allows job 1 to restore from server-A while the backup is still in progress? What do I need to do or instruct the DBA to do for this?

Thanks in advance.
