We currently have a backup and restore job which runs on a weekly basis and the database size is more than 10TB.Split backup method is followed for taking the database backup and the same is restored on another server.During restoration we are seeing very high network utilization which is affecting the ETL load performance.
Is this a routined process ? if yes then you should look for another approach like log shipping , replication as mentioend above. as playing with 10Tb data every week is not a handy task . IO , network issues always wil be there another things. there could be chances that backup/resotred got failed due to resources crunch.
